Abstract:
BACKGROUND: Indications and applications of percutaneous transluminal coronary angioplasty(PTCA) has been broaden in reccent years. However,we considered many aspects in performing angioplasty in patient with multivessel disease. There were procedural success rate, complication, risk, restenosis and long-term effect. So we evaluated the initial success rate, safety and follow-up results. METHODS: To assess the likelihood of initial success in patients with multivessel coronary artery disease, single or multiple site angioplasy were performed at 449 lesions from 273 patients(Male 202,Female 71, Mean age 60.0+/-9.4 years). To evaluate the restenosis rate of angioplasty in multivessel disease, follow-up coronary angiogram were performed at 164 lesions from 95 patients at average 6months after angioplasty. RESULTS: The extent of coronary artery disease revealed that two vessel disease were 200(73.3%) and triple vessel disease were 73(26.7%). Single vessel angioplasty(SVA) was performed in 180(40.1%) lesions and multivessel angioplasty(MVA) was performed in 269(59.9%) lesions. Procedural success was achieved 377(84.0%) out of total 449 lesions. The proccdural success rate was 81.1% in SVA and 85.9% in MVA. According to major epicardial coronary artery, procedural success rate of left anterior descending artery was 82.0%, left circumflex artery 92.4% and right coronary artery 79.4%. According to angiographic morphology of lesions, procedural success rate of type A was 95.7%, type B 88.9% and type C 56.4%. Complete revascularization was done in 87 patients(31.9%) out of 273 patients. Major cause of failure of angioplasty in multivessel disease was inability to pass the guide wire cross the lesion due to total occlusion. Complications included dissection in 101, acute closure in 7(9.7%), coronary artery perforation in 2, cardiogenic shock in 1 and ventricular fibrillation in 1. Follow-up coronary angiography revealed the restenosis rate was 42.2%. CONCLUSION: Coronary angioplasty in selected patients with multivessel coronary artery disease might be useful and have relatively good immediate and long-term results.
