Angiographic results of the cobalt chromium Vision and Mini-Vision stents

Background Drug-eluting stents (DES) have been shown to reduce repeat revascularizations compared with their bare-metal stent (BMS) platforms. Modern BMS may be associated with better angiographic results compared with the older BMS platforms. In the Basel Stent Kosten Effektivitats Trial (BASKET), target vessel revascularization after six months was nonsignificantly different between DES and BMS with clinical follow-up. Objectives To evaluate angiographic results of the cobalt chromium Vision and Mini-Vision stents (Abbott Vascular, USA). Methods A total of 247 consecutive patients with 293 de novo lesions in native coronary arteries were treated with cobalt chromium Vision (n=184; stent diameter 2.75 mm to 4.0 mm) or Mini-Vision stents (n=109; stent diameter 2.0 mm to 2.5 mm), and scheduled for six months of angiographic follow-up. The primary end point was in-stent late loss after six months. Results Acute coronary syndromes were present in 83.4% (n=206) of patients. The preinterventional reference diameter of Vision stents was 2.70±0.34 mm and for Mini-Vision stents, it was 2.13±0.27 mm (P
