natriuretic-peptide--brain and Blood-Loss--Surgical

The current review focuses on patients with congenital heart disease (CHD) with regard to recent trends in global demographics, healthcare provision for noncardiac surgery, as well as anesthetic and perioperative care for these patients.. About 40 years after milestones of surgical innovation in CHD, the number of adults with CHD (ACHD) now surpasses those of children with CHD. This development leads to the fact that even patients with complex CHD managed for noncardiac surgery are not restricted to highly specialized centers. However, preoperative risk assessment for anesthesia in these patients is complex due to underlying cardiac morbidity and substantial CHD-associated noncardiac morbidity. In addition to clinical assessment and echocardiography, biomarker measurement may be a clinically useful tool to estimate severity of heart failure in CHD patients. The high negative predictive value of NT-proBNP makes it particularly valuable as a screening tool. Further, morbidity and mortality in ACHD patients are mainly caused by arrhythmias and therefore are also relevant for perioperative management. Adverse events and perioperative death in ACHD patients in cardiac and noncardiac surgery are frequently related to intraoperative anesthetic care.. Medical progress in treatment of CHD has shifted morbidity and mortality of these patients largely to adulthood. Future investigations including risk stratification of ACHD patients are necessary to further improve perioperative management, especially for low-risk and high-risk noncardiac management.

The adverse effects of left atrial appendage (LAA) closure have not yet been evaluated. This study aimed to prove the safety and low invasiveness of LAA resection through our thoracoscopic stand-alone left atrial appendectomy experience.. Eighty-seven patients [mean age 68 ± 9 years, 68 men (78%), mean congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke or transient ischaemic attack to thromboembolism, vascular disease, age 65-74 years and sex category (CHA2DS2-VASc) score 2.9 ± 1.6 points] who had undergone thoracoscopic left atrial appendectomy were selected. The operative and clinical data (left atrial diameter, left ventricular diameter of systole/diastole, ejection fraction, brain natriuretic peptide and human atrial natriuretic peptide) were evaluated. All procedures were performed without cardiopulmonary bypass or cardiac arrest. The LAA was resected with an endoscopic linear cutter device. Except for 1 case with severe pleural adhesion, all operations were performed thoracoscopically.. The preoperative and postoperative data are as follows: left atrial diameter 43 ± 5 mm and 43 ± 5 mm (P = 0.8); left ventricular diameter of systole/diastole 50 ± 5/35 ± 6 mm and 48 ± 5/34 ± 6 mm (P < 0.01); ejection fraction 57 ± 10% and 56 ± 10% (P = 0.11); brain natriuretic peptide 97 ± 77 pg/ml and 72 ± 65 pg/ml (P < 0.01) and human atrial natriuretic peptide 73 ± 64 pg/ml and 96 ± 67 pg/ml (P = 0.03), respectively. The mean volume of bleeding in the operation was very small (<10 ml). The mean length of postoperative in-hospital stay was 3.8 ± 1.8 days. All the patients were discharged while maintaining their preoperative activities of daily living without major complications. No thrombus or residual stumps were detected during the 3-month postoperative computed tomography follow-up. The perioperative heart function did not change significantly in this study. Bleeding with resection was minimal, and no rebleeding events occurred.. LAA resection did not affect negatively on the cardiac function and did not increase the risk of bleeding risk.
