RESUMO
The stent was placed in 528 coronary artery segments (39% complicated lesions) in 448 patients with coronary artery disease and no previous invasive interventions. Immediate angiographic success was 99.8% with no case of acute thrombosis. Six months survival without restenosis, angina, and reintervention was 83%. Repeat angiography was carried out in 432 patients with 502 stented stenoses. Index of vessel diameter loss and level of restenosis were 0.32+/-0.26, and 15,6%, respectively. Fifty four patients with in-stent restenosis were subjected to successful repeat revascularization. Eighteen months survival without myocardial infarction and reintervention was 70%. The study demonstrated favorable effect of TAIS on 18 month rate of thrombosis and restenosis in patients with native atherosclerotic lesions.
