ABSTRACT
From April 1988 to December 1991, we implanted 75 coronary stents (29 self-expanding and 46 balloon expandable) in 62 patients. All had New York Heart Association class II to IV angina, and 11 (18%) had prior coronary artery bypass grafting (CABG). Thirty nine patients (63%) had 1 vessel disease, and 23 (37%) had multivessel disease. The mean left ventricular ejection fraction was 63 +/- 11%. The indications for coronary stenting were acute post percutaneous transluminal coronary angioplasty (PTCA) occlusion in 45 (73%) (bail out stenting) and restenosis in 17 (24%) (elective stenting). There were 52 single stent (84%), 7 double stent (11%), and 3 triple stent procedures (5%). The mean stent diameter was 3.8 +/- 0.5 mm, and the mean stent length 21 +/- 7 mm. The attempted vessels were the left main coronary artery in 2(3%), left anterior descending coronary artery in 27 (44%), left circumflex coronary artery in 8 (13%), right coronary artery in 17 (27%), and a saphenous vein graft in 8 (13%). Technical success was achieved in 74 stent implantations (98%). Technical failure occurred in 1 case with a self expanding stent because of inability to reach the lesion. In hospital complications (mean hospital stay 10 +/- 10, range 2-60 days) included temporary stent occlusion in 2 patients (3%) treated by balloon dilatation and thrombolysis with intravenous urokinase, permanent stent occlusion in 5 patients (8%), Q-wave infarction in 5 patients (8%), CABG in 4 patients (11%), and death in 3 patients (5%). At least 1 major complication (Q wave infarction, CABG, or death) occurred in 8 patients (13%).(ABSTRACT TRUNCATED AT 250 WORDS)
