Allopurinol reduces formation of cytotoxic free radicals during myocardial ischemia/reperfusion in animals. To evaluate the effect of allopurinol on cardiac performance and metabolism after coronary bypass in humans, we divided 33 patients into two groups: 15 patients (controls) received no allopurinol and 18 patients received 200 mg allopurinol(More)
The safety and efficacy of amiodarone and propafenone in converting atrial fibrillation or flutter after cardiac surgery were compared in a randomized double-blind trial. Eighty-four patients with sustained atrial tachyarrhythmias of more than 30 min' duration, stable hemodynamic status and neither preoperative atrial arrhythmias nor treatment with other(More)
A 49-year-old woman with isolated atresia of the left main coronary artery is presented. The patient who suffered from angina underwent myocardial revascularization 14 years after the onset of symptoms. A left internal mammary artery to left anterior descending coronary artery bypass was performed. Twenty months after the operation, the patient is free from(More)
Fibrin adhesive was used 72 times in a group of 67 patients undergoing elective coronary artery bypass graft surgery. The indications were prophylactic sealing of potential sources of bleeding, topical hemostasis (control of bleeding sites dangerous or difficult to suture), and fixation of the graft in the optimal position. The method of glue application(More)
The rising costs of health care have forced policy makers to make choices, and new treatments are increasingly assessed in terms of the balance between additional costs and additional effects. The recent recognition that stenting has a major and long-lasting effect enhancing balloon PTCA procedure has made it imperative to compare in patients with(More)
Endothelial damage of human saphenous vein (HSV) during the preparation for bypass grafting could affect graft patency. Improving the preservation of HSV could provide a longer and better patency of coronary artery bypass grafts. An electron microscopic comparative analysis of the effects of three different preservatives on HSV morphology was carried on in(More)
This case-report describes a large pseudoaneurysm of the proximal left anterior descending coronary artery, fissured in the pericardium, developed 4 days after rotational and directional atherectomy followed by stent implantation. A successful percutaneous repair was obtained with 2 vein-covered stents implanted and expanded under ultrasound guidance.
OBJECTIVE Chordal transposition was advocated for correction of anterior mitral prolapse. We have evaluated the early and late results of this technique in different anatomical presentations. METHODS From 1986 to 1995, 185 mitral valve repairs were carried out for pure mitral regurgitation due to a degenerative disease. Eighty-nine patients had either an(More)
OBJECTIVE A prospective angiographic study was undertaken to investigate, with an objective analysis, the global and regional wall response to myocardial revascularization. METHODS Thirty-one patients (30 men and 1 woman, mean age, 61 years) with a left ventricular ejection fraction of less than 0.30 were admitted to our institution between 1992 and 1995(More)
