✦ Synopsis

We prospectively studied 223 patients (288 lesions) who underwent elective or bail out implantation of 309 NIR stents (Scimed, Boston Scientific Corporation, Galway, Ireland). Most lesions (68.4%) had unfavorable characteristics (type B2 or C). Primary success in stent deployment was achieved in 305 (98.6%). There was no Q-wave myocardial infarction. Emergency coronary artery bypass grafting (CABG) was required in 1 patient and 1 death occurred. Subacute thrombosis rate was 0.4%. Reference diameter was 2.65 ؎ 0.67 mm. Minimum luminal diameter (MLD) increased from 0.62 ؎ 0.45 to 2.69 ؎ 0.57 mm and diameter stenosis decreased from 78.3 ؎ 13.4% to 12.7 ؎ 5.9%. Clinical follow-up was performed in the first 135 patients for 5.3 ؎ 1.6 months and repeat angiography was undertaken in 35 (16%) with recurrence of symptoms at 4.6 ؎ 1.3 months. Clinical restenosis rate was 9.6%. We conclude that the NIR coronary stent exhibits favorable performance characteristics and appears to be safe and efficacious in the treatment of coronary lesions even in the presence of high-risk characteristics.
