Abstract
Background Several stents are now available for the treatment of failed or suboptimal angioplasty. However, one of the limitations of stents is difficult to deploy especially in tortuous vessels, lesions at a bend, and distal to previously deployed stents. The AVE Micro-II stent has a very low profile(1.65mm), optimum radio-opacity, and highly flexible properties. It is mounted on a semi-compliant balloon with a monorail delivery system. Therefore, it is easy to operate and feasible in tortuous, distal lesions and variety of lesion lengths. We report clinical outcomes and angiographic follow up results of AVE Micro-II stent. Methods Between January 1996 and September 1996, 77 patients were stented with the AVE Micro-II stent. Six-months follow-up angiogram was performed in 57 patients(64 lesions, follow-up rate : 74%). Results The overall angiographic restenosis rate was 26.6%. By univariable analysis, the rate of restenosis was significantly higher for stents in angulated lesions, in smaller post-stent luminal diameter, in the left anterior descending artery lesion than the right coronary artery, in ostial lesion(p=0.02), in peristent dissecting lesions(p=0.02), in tortuous proximal vessels(p=0.03). Stenting of angulated lesions(p=0.0001, Odds ratio=54.64), small post-stent luminal diameter(p=0.01, Odds ratio=5.46), and the left anterior descending artery than the right coronary artery(p=0.03, Odds ratio=17.2) were the strong independent predictors of restenosis in a multiple logistic regression analysis. Event-free survival(freedom from death, myocardial infarction or revascularization) was 80.7% at 6 months. Conclusions 1) The AVE Micro-II stent can be placed safely and efficiently. 2) The angiographic restenosis rate was 26.6%, and 80.7% of patients remained free of cardiovascular events at 6 months. 3) Stenting of angulated lesions, small post-stent luminal diameter, and the left anterior descending artery than the right coronary artery are associated with higher rates of restenosis.
