Medical history comprised several episodes of acute decompensated heart failure due to supraventricular tachyarrhythmia with need for hospitalization during the last 2 years. He additionally had two-vessel coronary artery disease with myocardial infarction, pulmonary hypertension, chronic atrial fibrillation, peripheral arterial disease, and chronic kidney disease (stage 3).
