In the past, coronary artery bypass grafting was the treatment of choice for patients with symptomatic multi vessel coronary artery disease, but in recent years per cutaneous transluminal coronary angioplasty (PTCA) accepted as an alternative approach to revascularization. To assess the initial success and in hospital results of coronary angioplasty of more than one lesion per procedure in patients with multi vessel coronary artery disease, a retrospective analysis of patients who underwent selective coronary angioplasty at Imam Khomeini medical center from 1994-1997 were peformed. From 1994 to 1997 per cutaneous transluminal coronary angioplasty (PTCA) were done in 257 patients, that 201 (78.2 percent) were male and their age range 23-73 years. The numbers of patients with multi vessel coronary artery disease were 98 (38.13 percent), that complete revascularization (PTCA of more than one lesion per procedure) underwent in 34 (13.58 percent) of them (27 men, 7 women, age: mean±SD 48±9.8 range 30-70). A total of 71 lesions were tried, that 22 (31 percent) were type A, 45 (63.4 percent) were type B, and 4 (5.6 percent) were type C. Among patients 21 (61.8 percent) had unstable angina and 13 (38.2 percent) had stable angina. Procedures were successful in 68 (95.8 percent) of lesions and 31 (91.2 percent) patients were discharged fro procedural complications included 3 (8.8 percent) non-Q wave myocardial infarction and no mortality. Without any complication, (success defined as residual stenosis <50 percent). As a conclusion, in selected patients with multi vessel coronary artery disease PTCA of more than one lesion per-procedure is effective and safe.
