Results of 130 consecutive percutaneous transluminal coronary angioplasty (PTCA) procedures in single and multiple vessel coronary artery disease (CAD).
Over the last 1-year period, we performed 130 consecutive percutaneous transluminal coronary angioplasty (PTCA) procedures in 108 patients, 103 of them were males and 5 females. Their mean age was 50.9 +/- 6.83 years (range 33-70). All of them were symptomatic, manifested by acute infarction in 18 (17%), chronic stable angina in 30 (28%), unstable angina in 5 (5%) and post-myocardial infarction angina in 55 (51%) cases. Among these patients, single-vessel CAD was present in 42 (39%), double-vessel in 37 (34%) and triple-vessel CAD in 11 (10%) patients. Nine patients (8.3%) had total occlusion, and 18 (16.6%) had tandem or bifurcation lesions of target artery. Of the 112 PTCA procedures (excluding those in acute infarction), 53 (47%) were performed on LAD, 29 (26%) on RCA, and 30 (27%) on circumflex artery, with success rates of 86.7%, 83.3% and 82.7% respectively. The overall success rate was 85% (95 of 112). The PTCA was successful in 36 of 42 (85.7%), 32 of 37 (86.5%) and 9 on 11 (82%) patients with single, double and triple-vessel CAD respectively. The mean diameter stenosis reduced from 67.1 +/- 16.54% to 19.9% +/- 10.9%. PTCA was unsuccessful in 17 (15%) due to failure to cross the lesion in 11 (9.7%), failure to dilate in 1 (0.9%) and abrupt reclosure of dilated segment in 5 (4.4%). Four (3.5%) patients underwent CABG. Two patients had redo PTCA owing to restenosis at about 6 months of first PTCA.(ABSTRACT TRUNCATED AT 250 WORDS)
