عنوان انگلیسی Immediate Small Side Branch Occlusion after Percutaneous Coronary Intervention
چکیده انگلیسی مقاله Background: Small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. Nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch occlusion . The aim of this study was to compare the patency of small (≥0.5 and ≤1.5 mm in diameter) side branches with respect to bare metal vs. drug-eluting stents immediately after their deployment . Methods: This prospective bi-center study, conducted between June 2005 and January 2007, enrolled 82 patients treated with ≥1 of two stents (TAXUS TM Liberte TM or Liberte TM ). Side branches ≥0.5 and < 1.5 mm in diameter arising from the main vessel at the lesion site were evaluated . Results: Thirty-eight patients were treated with 42 Liberte TM stents (58 side branches) and forty-four patients with 50 TAXUS TM Liberte TM (102 side branches). The rate of small side branch occlusion was 35.3% (36) in the TAXUS TM Liberte TM group compared to 29.31% (15) in the Liberte TM group (P-value= 0.7). The presence of type 1 side branch morphology (Lefevre classification) was the most powerful predictor of small side branch occlusion (P-value=0.03). Conclusion: This study shows that drug-eluting stents are not inferior to bare metal stents as regards small side branch occlusion during coronary stenting .
