Zotarolimus-eluting stents in patients with native coronary artery disease: clinical and angiographic outcomes in 1,317 patients.
Early studies of a cobalt-based alloy stent coated with the novel antiproliferative agent zotarolimus and a phosphorylcholine polymer have demonstrated significant reductions in angiographic restenosis and target vessel revascularization compared with bare metal stents. However, the generalizability of the angiographic outcomes and clinical benefit of zotarolimus-eluting stents (ZESs) to a more real-world patient population is undetermined. Clinical and angiographic outcomes in 1,317 patients treated with the ZES in the first 4 trials of the Endeavor ZES (Medtronic Vascular, Santa Rosa, CA) clinical trials program were pooled for systematic analysis. Protocol-specified follow-up angiography was performed at 8 or 12 months for a subset of 750 of these patients, and clinical follow-up was performed at 9 months after the index procedures in all patients. Diabetes mellitus was present in 22.5% of patients, the mean reference vessel diameter was 2.73 mm, and the mean lesion length was 14.59 mm. At 8 months (12 months for ENDEAVOR I), mean +/- SD in-stent late luminal loss was 0.61 +/- 0.49 mm. In-stent late luminal loss was greatest in larger caliber (>2.9 mm) vessels (0.65 +/- 0.49 mm) and longer (>16.3 mm) lesions (0.70 +/- 0.52 mm) but did not statistically vary according to diabetic status. At 9 months, overall rates of target lesion revascularization (TLR) and major adverse cardiac events (MACE) were 4.9% and 7.7%, respectively. The rate of TLR at 12 months was not significantly different relative to diabetes and lesion length >16.3 mm (7.2% and 7.7%, respectively), although TLR was significantly more common when reference vessel diameter was <2.5 mm (8.5%; p = 0.013). At 24 months, overall rates of TLR and MACE were 6.5% and 9.9%, respectively. The overall 24-month rate of stent thrombosis was 0.3%, with no events occurring >14 days after the procedure. Despite varied clinical and angiographic characteristics, treatment with the ZES is associated with consistently low rates of TLR and overall major adverse events, including stent thrombosis. Although these findings indicate the efficacy and safety of the ZES over the time course of the first 4 ENDEAVOR clinical trials, additional ongoing study with more open patient inclusion criteria (including long lesions, small vessels, bifurcations, etc) will be important for discerning whether comparable clinical outcomes can be extended to lesion subsets of higher complexity.

Angiographic outcomes of Orsiro biodegradable polymer sirolimus-eluting stents and Resolute Integrity durable polymer zotarolimus-eluting stents: results of the ORIENT trial.
We performed a randomised controlled open-label non-inferiority trial to compare angiographic outcomes between the ultra-thin strut, biodegradable hybrid polymer Orsiro sirolimus-eluting stent (O-SES) and the durable biocompatible polymer Resolute Integrity zotarolimus-eluting stent (R-ZES).. A total of 372 patients planned to undergo percutaneous coronary revascularisation were randomly assigned 2:1 to treatment with O-SES or R-ZES (250 and 122 patients, respectively). O-SES was non-inferior to R-ZES for the primary endpoint, in-stent late lumen loss at nine months (median 0.06 mm [interquartile range, -0.09 to 0.24 mm] versus 0.12 mm [-0.07 to 0.32 mm]; p for non-inferiority <0.001; p for superiority=0.205). Percent diameter stenosis was significantly lower in the O-SES group than in the R-ZES group (15.0 [10.0 to 20.0] versus 20.0 [13.3 to 26.0]; p=0.002). Target lesion failure occurred in 2.4% and 3.3% of the O-SES and R-ZES groups, respectively (p=0.621). Subgroup analyses showed consistently similar outcomes between the two groups in terms of the primary endpoint, except for the diabetic subgroup.. O-SES was non-inferior to R-ZES in terms of in-stent late loss at nine months. Angiographic restenosis and clinical adverse events were low in both groups. This study confirms the good safety and efficacy profiles of both contemporary coronary stents.

DESyne novolimus-eluting coronary stent is superior to Endeavor zotarolimus-eluting coronary stent at five-year follow-up: final results of the multicentre EXCELLA II randomised controlled trial.
Newer-generation drug-eluting stents (DES) have been shown to be superior to first-generation DES. Current-generation DES have zotarolimus, everolimus or biolimus as antiproliferative drugs. Novolimus, a metabolite of sirolimus, has been specifically developed to provide efficacy similar to currently available agents at a lower dose and thus requires a lower polymer load. We report the final five-year outcomes of the EXCELLA II trial comparing a zotarolimus-eluting stent (ZES) with a novolimus-eluting stent (NES).. EXCELLA II is a prospective, multicentre, single-blind, non-inferiority clinical trial. Patients (n=210) with a maximum of two de novo lesions in two different epicardial vessels were randomised (2:1) to treatment with either NES (n=139) or ZES (n=71). At five-year follow-up, patients in the NES group had a significantly lower incidence of the patient-oriented (HR 0.53, 95% CI: 0.32-0.87, p=0.013) and device-oriented (HR 0.38, 95% CI: 0.17-0.83, p=0.011) composite endpoints. There was no difference in cardiac death and definite/probable stent thrombosis between the two groups; however, there was a trend towards reduction in myocardial infarction and repeat revascularisation in the NES group at five-year follow-up.. At five-year follow-up, the incidence of device- and patient-oriented events was significantly lower in the NES group. Further studies, adequately powered for clinical outcomes, are warranted.

Very thin strut biodegradable polymer everolimus-eluting and sirolimus-eluting stents versus durable polymer zotarolimus-eluting stents in allcomers with coronary artery disease (BIO-RESORT): a three-arm, randomised, non-inferiority trial.
In patients with coronary artery disease, treated with durable polymer-coated drug-eluting stents, the life-long presence of the polymer might delay arterial healing. Novel very thin strut biodegradable polymer stents, which leave only a bare metal stent after polymer resorption, might improve long-term outcome. We investigated in allcomers the safety and efficacy of three stents eluting either everolimus, sirolimus, or zotarolimus, often clinically used but never compared, of which the biodegradable polymer everolimus-eluting stent was never before assessed in allcomers.. The large-scale, investigator-initiated, multicentre, assessor and patient blinded, three-arm, randomised, BIO-RESORT non-inferiority trial was done at four clinical sites in the Netherlands. All-comer patients were aged 18 years or older, capable of providing informed consent, and required a percutaneous coronary intervention with drug-eluting stent implantation according to clinical guidelines or the operators' judgment. Exclusion criteria were: participation in another randomised drug or device study before reaching the primary endpoint of that study; planned surgery necessitating interruption of dual antiplatelet therapy within the first 6 months; known intolerance to components of the investigational product or medication required; uncertainty about the adherence to follow-up procedures or an assumed life expectancy of less than 1 year; or known pregnancy. Web-based computer-generated allocation sequences randomly assigned patients (1:1:1) to treatment with very thin strut biodegradable polymer everolimus-eluting or sirolimus-eluting stents (which differ substantially in type, amount, distribution, and resorption speed of their respective coating), or thin strut durable polymer zotarolimus-eluting stents. The primary endpoint was a composite of safety (cardiac death or target vessel-related myocardial infarction) and efficacy (target vessel revascularisation) at 12 months of follow up with a very thin strut biodegradable polymer of either everolimus-eluting or sirolimus-eluting stents, compared with durable polymer zotarolimus-eluting stents, analysed by intention to treat (non-inferiority margin 3·5%). This trial was registered with ClinicalTrials.gov, number NCT01674803.. From Dec 21, 2012, to Aug 24, 2015, 3514 patients were enrolled and analysed, of whom 2449 (70%) had acute coronary syndromes, which included 1073 (31%) ST-elevation myocardial infarctions. 12 month follow-up of 3490 (99%) patients (three lost to follow-up; 21 withdrawals) was available. The primary endpoint was met by 55 (5%) of 1172 patients assigned to everolimus-eluting stents, 55 (5%) of 1169 assigned to sirolimus-eluting stents and 63 (5%) of 1173 assigned to zotarolimus-eluting stents. Non-inferiority of the everolimus-eluting stents and sirolimus-eluting stents compared with zotarolimus-eluting stents was confirmed (both -0·7% absolute risk difference, 95% CI -2·4 to 1·1; upper limit of one sided 95% CI 0·8%, p. At 12 month follow-up, both very thin strut drug-eluting stents with dissimilar biodegradable polymer coatings (eluting either everolimus or sirolimus) were non-inferior to the durable polymer stent (eluting zotarolimus) in treating allcomers with a high proportion of patients with acute coronary syndromes. The absence of a loss of 1 year safety and efficacy with the use of these two biodegradable polymer-coated stents is a prerequisite before assessing their potential longer-term benefits..

Complex patients treated with zotarolimus-eluting resolute and everolimus-eluting Xience V stents in the randomized TWENTE trial: comparison of 2-year clinical outcome.
To assess the differences in clinical outcome between complex patients treated with Resolute zotarolimus-eluting stents (ZES) versus Xience V everolimus-eluting stents (EES).. Nowadays, many complex patients with coronary disease are treated with percutaneous coronary interventions, using drug-eluting stents (DES).. We analyzed 2-year outcome data of 1,033 complex patients of the TWENTE trial, treated with second-generation Resolute ZES or Xience V EES. Complex patients had at least one of the following characteristics: renal insufficiency (creatinine ≥ 140 µmol/l); ejection fraction < 30%; acute myocardial infarction (MI) within previous 72 hrs; >1 lesion/vessel; >2 vessels treated; lesion length > 27 mm; bifurcation; saphenous vein graft lesion; arterial bypass graft lesion; in-stent restenosis; unprotected left main lesion; lesion with thrombus; or lesion with total occlusion. Target vessel failure (TVF), the primary composite endpoint of the trial, was defined as cardiac death, target vessel-related MI, or target vessel revascularization.. Among the 1,033 complex patients, 529 (51%) were treated with Resolute ZES and 504 (49%) with Xience V EES. Patient- and procedure-related characteristics were similar between DES groups. After 2-year follow-up, outcome was also similar between DES groups. TVF occurred in 12.1% of patients treated with Resolute ZES and 12.3% of patients treated with Xience V EES. In addition, DES groups did not differ significantly in cardiac death, MI, or target vessel revascularization-the individual components of TVF.. Complex patients treated with Resolute ZES and Xience V EES showed similar safety and efficacy during 2-year follow-up. © 2014 Wiley Periodicals, Inc.

Study design and rationale of "a multicenter, open-labeled, randomized controlled trial comparing three 2nd-generation drug-eluting stents in real-world practice" (CHOICE trial).
The second-generation drug-eluting stents (DES) have shown superiority in many studies relating to safety and efficacy when compared with the first-generation DES. However, it is unclear whether there are differences in efficacy and safety among the second-generation DES after long-term follow-up.. This multicenter, prospective, randomized, open-labeled trial will directly compare the efficacy and safety among the patients treated with either everolimus-eluting stent (EES), zotarolimus-eluting stent with biolinx polymer (ZES-R), or biolimus-eluting stent (BES) with minimal exclusion criteria. The primary end point is a patient-oriented composite consisted of cardiac death, myocardial infarction not clearly attributable to a nontarget vessel and clinically indicated target lesion revascularization at 24-month clinical follow-up post-index procedure. With the hypothesis that "BES is non-inferior to EES" or "BES is non-inferior to ZES-R" in primary end point, approximately 2,600 patients will be assigned to one of the types of stents using a web-based randomization system.. The CHOICE trial will directly compare the efficacy and safety of EES, ZES-R, and BES in everyday clinical practice for long-term follow-up.

Efficacy and safety of zotarolimus-eluting and sirolimus-eluting coronary stents in routine clinical care (SORT OUT III): a randomised controlled superiority trial.
In low-risk patients, the zotarolimus-eluting stent has been shown to reduce rates of restenosis without increasing the risk of stent thrombosis. We compared the efficacy and safety of the zotarolimus-eluting stent versus the sirolimus-eluting stent in patients with coronary artery disease who were receiving routine clinical care with no direct follow-up.. We did a single-blind, all-comer superiority trial in adult patients with chronic stable coronary artery disease or acute coronary syndromes, and at least one target lesion. Patients were treated at one of five percutaneous coronary intervention centres between January, 2006, and August, 2007. Computer-generated block randomisation and a telephone allocation service were used to randomly assign patients to receive the zotarolimus-eluting or the sirolimus-eluting stent. Data for follow-up were obtained from national Danish administrative and health-care registries. The primary endpoint was a composite of major adverse cardiac events within 9 months: cardiac death, myocardial infarction, and target vessel revascularisation. Intention-to-treat analyses were done at 9-month and 18-month follow-up. This trial is registered with ClinicalTrials.gov, number NCT00660478.. 1162 patients (1619 lesions) were assigned to receive the zotarolimus-eluting stent, and 1170 patients (1611 lesions) to receive the sirolimus-eluting stent. 67 patients (72 lesions) had stent failure, and six patients were lost to follow-up. All randomly assigned patients were included in analyses at 9-month follow-up; 2200 patients (94%) had completed 18-month follow-up by the time of our assessment. At 9 months, the primary endpoint had occurred in a higher proportion of patients treated with the zotarolimus-eluting stent than in those treated with the sirolimus-eluting stent (72 [6%] vs 34 [3%]; HR 2.15, 95% CI 1.43-3.23; p=0.0002). At 18-month follow-up, this difference was sustained (113 [10%] vs 53 [5%]; 2.19, 1.58-3.04; p<0.0001). For patients receiving the zotarolimus-eluting stent and those receiving the sirolimus-eluting stent, all cause-mortality was similar at 9-month follow-up (25 [2%] vs 18 [2%]; 1.40, 0.76-2.56; p=0.28), but was significantly different at 18-month follow-up (51 [4%] vs 32 [3%]; 1.61, 1.03-2.50; p=0.035).. The sirolimus-eluting stent is superior to the zotarolimus-eluting stent for patients receiving routine clinical care.. Cordis and Medtronic.

Comparison of zotarolimus-eluting and everolimus-eluting coronary stents.
New-generation coronary stents that release zotarolimus or everolimus have been shown to reduce the risk of restenosis. However, it is unclear whether there are differences in efficacy and safety between the two types of stents on the basis of prospectively adjudicated end points endorsed by the Food and Drug Administration.. In this multicenter, noninferiority trial with minimal exclusion criteria, we randomly assigned 2292 patients to undergo treatment with coronary stents releasing either zotarolimus or everolimus. Twenty percent of patients were randomly selected for repeat angiography at 13 months. The primary end point was target-lesion failure, defined as a composite of death from cardiac causes, any myocardial infarction (not clearly attributable to a nontarget vessel), or clinically indicated target-lesion revascularization within 12 months. The secondary angiographic end point was the extent of in-stent stenosis at 13 months.. At least one off-label criterion for stent placement was present in 66% of patients. The zotarolimus-eluting stent was noninferior to the everolimus-eluting stent with respect to the primary end point, which occurred in 8.2% and 8.3% of patients, respectively (P<0.001 for noninferiority). There were no significant between-group differences in the rate of death from cardiac causes, any myocardial infarction, or revascularization. The rate of stent thrombosis was 2.3% in the zotarolimus-stent group and 1.5% in the everolimus-stent group (P=0.17). The zotarolimus-eluting stent was also noninferior regarding the degree (+/-SD) of in-stent stenosis (21.65+/-14.42% for zotarolimus vs. 19.76+/-14.64% for everolimus, P=0.04 for noninferiority). In-stent late lumen loss was 0.27+/-0.43 mm in the zotarolimus-stent group versus 0.19+/-0.40 mm in the everolimus-stent group (P=0.08). There were no significant between-group differences in the rate of adverse events.. At 13 months, the new-generation zotarolimus-eluting stent was found to be noninferior to the everolimus-eluting stent in a population of patients who had minimal exclusion criteria.

Angiographic, IVUS and OCT evaluation of the long-term impact of coronary disease severity at the site of overlapping drug-eluting and bare metal stents: a substudy of the ODESSA trial.
A potentially adverse vascular response to overlapping drug eluting stents (DES) has been suggested in current research.. To evaluate the impact of baseline disease severity at the site of stent overlap.. This is a substudy of ODESSA, a prospective, randomised controlled trial designed to evaluate healing of overlapping stents. 71/77 patients with a total of 86 overlapping stents were studied: 25 sirolimus, 24 paclitaxel, 26 zotarolimus-eluting stents; and 11 bare metal stents (BMS). Patients were categorised into high-grade stenosis (HGS, ≥ 70% diameter stenosis) and low-grade stenosis (LGS, <70%) at the site of stent overlap. Angiography and intravascular ultrasound were performed after stent deployment and repeated at 6 months, together with additional optical coherence tomography. Images were analysed by an independent core laboratory. End points were binary restenosis, percentage neointimal hyperplasia (%NIH), mean lumen and stent areas and degree of strut coverage/apposition at overlapping stents at 6 months. Stent overlaps occurred in 49 HGS and 37 LGS. Restenosis was found in 5/6 HGS versus 0/5 LGS treated with overlapping BMS (p=0.01) and 4/43 HGS versus 0/32 LGS treated with overlapping DES. There was a trend towards higher %NIH at BMS overlap in HGS versus LGS (p=0.07). DES overlaps had lower lumen and stent areas and similar %NIH in HGS versus LGS. Any uncovered or malapposed struts occurred more often in overlapping DES at LGS than at HGS (59.4% vs 32.6%, p=0.03).. Overlapping DES in normal-appearing coronary segments showed a higher incidence of uncovered or malapposed struts, while restenosis occurred exclusively in overlapping stents at HGS. These findings should be considered when deploying overlapping stents.

Modified T-stenting with intentional protrusion of the side-branch stent within the main vessel stent to ensure ostial coverage and facilitate final kissing balloon: the T-stenting and small protrusion technique (TAP-stenting). Report of bench testing and
To describe a novel modification of the T-stenting technique and to report the bench test as well as the first clinical results obtained.. The best technique to treat bifurcated coronary lesions has not been defined.. This novel modification of the T-stenting technique is based, after stenting of the main vessel (MV) and kissing balloon, on the intentional minimal protrusion of the side-branch (SB) stent within the MV. Final kissing balloon is performed using the balloon kept uninflated into the MV before SB stenting. The technique was tested in vitro and applied in two independent series of patients undergoing elective drug-eluting stent implantation on one bifurcated lesion. Bifurcated lesions were classified according to the Medina classification. Patients' outcome up to 9 month was prospectively assessed.. The bench test showed perfect coverage of the bifurcation with minimal stent's struts overlap at the proximal part of SB ostium and a small, single layer stent struts, neo-carina not affecting the MV patency. Seventy-three complex patients (67% of Medina 1,1,1 lesions; 44% of unprotected distal left main lesions) were treated with sirolimus-, paclitaxel-, or zotarolimus-eluting stents using the TAP technique. Procedural success was achieved in all cases and the clinical outcome up to 9 month was characterized by a low rate of clinically-driven target vessel revascularization (6.8%).. The TAP-stenting is a modification of the T-stenting technique which allows full coverage of bifurcated lesions and facilitates final kissing balloon. The first clinical experience suggests that this technique may be practical, thus calling for further evaluations of the technique.

A randomized comparison of sirolimus-eluting stent implantation with zotarolimus-eluting stent implantation for the treatment of total coronary occlusions: rationale and design of the PRImary Stenting of Occluded Native coronary arteries III (PRISON III)
Primary intracoronary drug-eluting stent placement after the successful crossing of total coronary occlusions decreases restenosis rate at long-term follow-up compared with bare-metal stent implantation. The PRISON II trial was the first randomized study to show the safety and efficacy of sirolimus-eluting stents in patients with totally occluded native coronary arteries. The sirolimus-eluting stent is superior to the bare-metal stent in treating patients with total coronary occlusions, with significant reduction in angiographic binary in-stent and in-segment restenosis resulting in significantly reduced need for target lesion and target vessel revascularization. Whether sirolimus-eluting stents are superior to other drug-eluting stents in total coronary occlusions is unknown. In this prospective, randomized trial, sirolimus-eluting stent implantation will be compared with zotarolimus-eluting stent implantation for the treatment of total coronary occlusions. A total of 300 patients will be followed for up to 5 years with angiographic follow-up at 8 months. Quantitative coronary analysis will be performed by an independent core laboratory. The primary end point will be in-segment late luminal loss at 8 months angiographic follow-up.

Four-year clinical follow-up after implantation of the endeavor zotarolimus-eluting stent: ENDEAVOR I, the first-in-human study.
The Endeavor zotarolimus-eluting stent (ZES; Medtronic Vascular, Santa Rosa, CA) has been found to provide event-free clinical outcomes to 2 years for the treatment of symptomatic CAD by suppressing neointimal proliferation of the target lesion. The clinical outcomes of patients treated with the Endeavor ZES were evaluated at 4 years after implantation. One hundred consecutive patients with symptomatic ischemic heart disease due to de novo stenotic lesions of native coronary arteries were treated with the Endeavor ZES at 8 centers according to a standardized procedure. At 4 years, 3 patients were lost to follow-up analysis. The incidence of major adverse cardiac events (MACE; defined as death, myocardial infarction, emergent cardiac surgery, or repeat revascularization of the target lesion) was 2% at 4 months, 2% at 1 year, 3% at 2 years, 6.1% at 3 years, and 7.2% at 4 years. The difference in these rates was due to 4 deaths caused by cancer (metastatic melanoma, metastatic adenocarcinoma, small-cell cancer of the bladder, and lung carcinoma). From 2-4 years, there was an additional reported case of target lesion revascularization (TLR). A single case of stent thrombosis occurred at 10 days after the index procedure but no cases occurred thereafter. The treatment of patients with symptomatic CAD due to de novo lesions in native coronary arteries with the Endeavor ZES has sustained clinical benefits to 4 years, with very low rates of MACE and TLR.

The relation between clinical features, angiographic findings, and the target lesion revascularization rate in patients receiving the endeavor zotarolimus-eluting stent for treatment of native coronary artery disease: an analysis of ENDEAVOR I, ENDEAVOR I
The clinical and angiographic factors that predict clinically driven target lesion revascularization (TLR) in patients treated with the zotarolimus-eluting stent (ZES) are not known. Accordingly, the differences between ZES-treated patients who required TLR and ZES-treated patients who did not require TLR were examined in 1,306 patients enrolled in 4 pivotal trials of the Endeavor ZES (Medtronic Vascular, Santa Rosa, CA) for the treatment of symptomatic native coronary artery disease. TLR was performed in 64 patients (4.9%) by 9 months, with most cases (89.1%) occurring after 30 days. ZES-treated patients who required TLR had a greater incidence of 2- or 3-vessel disease (p <0.01), more stents implanted (p = 0.05), and lower device (p = 0.04) and procedure (p <0.01) success rates than ZES-treated patients who did not require TLR. The stents implanted in ZES-treated patients who later required TLR were also longer (p = 0.02) and smaller in diameter (p <0.01). Most angiographic outcomes at 8 months (12 months for ZES-treated patients in ENDEAVOR I) were worse for ZES-treated patients who later required TLR. At 9 months, 10.9% of the ZES-treated patients who required TLR had had myocardial infarctions, compared with 2.2% who did not require TLR (p = 0.001). Multivariate analysis identified older age (odds ratio [OR], 1.03; 95% confidence interval [CI], 1.00-1.06), male sex (OR, 1.79; 95% CI, 0.88-3.65), and longer lesion length (OR, 1.03; 95% CI, 0.99-1.07) as risk factors for TLR after ZES implantation (with a C statistic of 0.61, suggesting a modest discriminatory value). These data provide insight into the clinical and angiographic factors that predict TLR at 9 months in ZES-treated patients, making possible the focused surveillance of selected ZES-treated patients who might be at greater risk of TLR.

Intravascular ultrasound findings in ENDEAVOR II and ENDEAVOR III.
The results of 2 randomized controlled trials of the Endeavor zotarolimus-eluting stent (ZES; Medtronic Vascular, Santa Rosa, CA) were recently reported: ENDEAVOR II, in which the Endeavor stent was compared with the Driver bare metal stent (BMS; Medtronic Vascular), and ENDEAVOR III, in which the Endeavor stent was compared with the first-generation Cypher sirolimus-eluting stent (SES; Cordis Corporation, Miami Lakes, FL). To examine in detail the vascular responses to the Endeavor stent, serial intravascular ultrasound (IVUS) analyses were performed in subsets of patients in the 2 trials at baseline and 8-month follow-up. The investigators report results for various IVUS parameters and compare those with published results for the first-generation SES and paclitaxel-eluting stent (PES). The ZES demonstrated significantly improved effectiveness and equivalent safety compared with the BMS in ENDEAVOR II. Although the ZES seems to be slightly less effective at inhibiting intimal hyperplasia than the SES and PES, early results are indicative of an acceptable safety profile. This finding may be due in part to the relatively complete and uniform neointimal coverage associated with the ZES.

Real-world safety and efficacy of the endeavor zotarolimus-eluting stent: early data from the E-Five Registry.
The E-Five is a prospective, nonrandomized, multicenter global registry of patients receiving the Endeavor zotarolimus-eluting stent (ZES; Medtronic Vascular, Santa Rosa, CA) for the treatment of coronary artery stenosis. All consecutive procedures were included in the registry, without any specific anatomic or clinical exclusion criteria. Since October 2005, 8,318 patients have been enrolled in the E-Five Registry at 188 hospitals in Europe, South America, Australia, New Zealand, and Asia, and 10,343 lesions have been treated. The primary end point is the rate of major adverse cardiac events (MACE) at 1 year. Of the lesions treated, 60.3% were American College of Cardiology (ACC) and American Heart Association (AHA) type B2 or C lesions, and 16.5% were bifurcation stenoses. The average lesion length was 18.50 +/- 10.60 mm, and 50.6% of the lesions were > or =16 mm long. Clinical data have been analyzed for 1,989 of the patients (23.9%) receiving the Endeavor ZES in this registry, with 30-day clinical outcomes available for 1,985 of these 1,989 patients (99.8%). The acute procedure success rate in these patients was 98.6%, comparable with procedure success rates observed in previous Endeavor ZES clinical trials. The 30-day rate of MACE in these patients was just 1.7%, comparable with 30-day rates of MACE observed in previous ENDEAVOR clinical trials. In an early analysis of a subgroup of patients enrolled in the E-Five Registry, the Endeavor ZES demonstrated encouraging acute and 30-day outcomes in a real-world population of patients who underwent single-vessel or multivessel percutaneous coronary intervention.

Randomized, double-blind, multicenter study of the Endeavor zotarolimus-eluting phosphorylcholine-encapsulated stent for treatment of native coronary artery lesions: clinical and angiographic results of the ENDEAVOR II trial.
The use of the Endeavor stent might reduce restenosis and stent thrombosis at 9 months.. Patients (n = 1197) treated for single coronary artery stenosis were enrolled in a prospective, randomized, double-blind study and randomly assigned to receive the Endeavor zotarolimus-eluting phosphorylcholine polymer-coated stent (n = 598) or the same bare metal stent but without the drug or the polymer coating (n = 599). The 2 groups were well matched in baseline characteristics. Diabetes was present in 20.1% of patients; the mean reference vessel diameter was 2.75 mm; and the mean lesion length was 14.2 mm. The primary end point of target vessel failure at 9 months was reduced from 15.1% with the bare metal stent to 7.9% with the Endeavor (P = 0.0001), and the rate of major adverse cardiac events was reduced from 14.4% with the bare metal stent to 7.3% with the Endeavor (P = 0.0001). Target lesion revascularization was 4.6% with Endeavor compared with 11.8% with the bare metal stent (P = 0.0001). The rate of stent thrombosis was 0.5% with the Endeavor, which was not significantly different from 1.2% with the bare metal stent. In 531 patients submitted to angiographic follow-up, late loss was reduced from 1.03 +/- 0.58 to 0.61 +/- 0.46 (P < 0.001) in stent and from 0.72 +/- 0.61 to 0.36 +/- 0.46 (P < 0.001) in segment. The rate of in-segment restenosis was reduced from 35.0% to 13.2% with Endeavor (P < 0.0001). There was no excessive edge stenosis, aneurysm formation, or late acquired malapposition by intravascular ultrasound imaging. Differences in clinical outcome were maintained at 12 and 24 months (P < 0.0001).. Compared with bare metal stents, the Endeavor stent is safe and reduces the rates of clinical and angiographic restenosis at 9, 12, and 24 months.

Comparison of early-phase arterial repair following cobalt-chrome everolimus-eluting stent and slow-release zotarolimus-eluting stent: an angioscopic study.
Whether arterial repair following implantation of drug-eluting stents (DES) of the second generation differs among stent types remains unknown. We examined 41 DES placed in 28 patients (age 72 ± 7 years, male 89%) presenting with stable angina pectoris due to de novo lesions in native coronary arteries. Coronary angioscopy was performed 4 ± 1 months after stent implantation. Patients were divided into two groups based on the DES types: 22 cobalt-chrome everolimus-eluting stents (CoCr-EES) in 13 patients and 19 slow-release zotarolimus-eluting stents (R-ZES) in 15 patients. Neointimal coverage (NIC) was graded as: grade 0, stent struts exposed; grade 1, struts bulging into the lumen, although covered; grade 2, struts embedded in the neointima, but translucent; grade 3, struts fully embedded and invisible. NIC was defined as heterogeneous when the NIC grade variation was ≥1. Presence of thrombus was also investigated. Distribution of dominant NIC grade (CoCr-EES: grade 0, 9%; grade 1, 77%; grade 2, 9%; grade 3, 5%; R-ZES: grade 0, 16%; grade 1: 47%; grade 2, 37%; grade 3, 0%, P = 0.38) and heterogeneity of NIC (P = 0.43) were similar between CoCr-EES and R-ZES groups. Existence of thrombus was not significantly different in CoCr-EES and R-ZES (18 versus 42%, P = 0.17). Arterial repair occurred without significant differences between CoCr-EES and R-ZES 4 months after implantation.

Impacts of lesion angle on incidence and distribution of acute vessel wall injuries and strut malapposition after drug-eluting stent implantation assessed by optical coherence tomography.
To investigate the impact of lesion angle on the incidence and distribution of acute vessel wall injuries and incomplete stent apposition (ISA) following second-generation drug-eluting stent (DES) implantation using optical coherence tomography (OCT). Several ex vivo studies demonstrated that angled arterial walls are exposed to imbalanced mechanical stress from deployed stents.. We included 243 lesions treated with a single DES (148 everolimus-eluting stent and 95 zotarolimus-eluting stent). Angled lesions were defined as lesions with angle ≥45° on an angiogram (n = 58). The vessel wall injuries and ISA were evaluated by OCT. The results were compared with non-angled lesions (<45°, n = 185). The incidence of instent dissection, thrombus, and ISA was significantly higher in the angled group than in the non-angled group (84.5 vs. 63.2%, P < 0.01; 55.2 vs. 35.1%, P < 0.01; 75.9 vs. 44.9%, P < 0.001, respectively). In the angled group, the normalized tissue protrusion volume around the centre of angle (6.59 ± 6.81, mm(3) × 10(2)) was higher than in the distal sub-segment (2.21 ± 2.87, mm3 × 10(2), P < 0.001), in the proximal sub-segment (4.14 ± 5.34, mm3 × 10(2), P = 0.02), and in the non-angled group (3.30 ± 2.81, mm3 × 10(2), P < 0.001). The incidence of major adverse cardiac events within 12 months was similar between the groups.. Angled coronary lesions had a higher incidence rate of OCT-detected vessel wall injuries and ISA compared with non-angled lesions following second-generation DES implantation. Further studies are needed to understand the long-term clinical significance of these findings.

In-hospital and 12-month postprocedural clinical outcome of coronary bifurcational lesion treatment with the endeavor stent.
The zotarolimus-eluting stent (ZES) has been documented as significantly reducing restenosis and target lesion revascularization (TLR) requirement compared to bare metal stents (BMS).. In this single-centered, prospective study we sought to evaluate the short- and medium-term outcomes of ZES placement in bifurcated coronary artery lesions. Between August 2006 and December 2007, 107 consecutive patients (110 bifurcations) were recruited to have ZES placement in the lesion. The provisional T stenting (PTS) technique was used in 96.3%. Angiographic success was 100% in main vessel (MV) cases and 97.2% in that of side branch (SB).. With a mean follow-up of 12.4 +/- 1.77 (mean +/- SD) months there were four deaths, three from cardiac cause (2.85%). There were 18 patients (19 bifurcations) requiring TLR (17.59%) for clinical reasons. The only predictor of TLR was the use diameter of ZES Topics: Adult; Aged; Aged, 80 and over; Cardiac Catheterization; Coronary Angiography; Coronary Disease; Drug-Eluting Stents; Equipment Design; Female; Follow-Up Studies; Humans; Inpatients; Male; Middle Aged; Prospective Studies; Sirolimus; Time Factors; Treatment Outcome | 2010 |
