Abstract 14367: Comparison of 5 Years Clinical Outcome of Drug-Eluting Stent Implantation in High-Angled (≥70°) Bifurcation and Lower-Angled (≤70°) Bifurcation Lesion of Unprotected Left Main Coronary Arteries
Aim: The aim of study is to compare the 5 years clinical outcome of drug-eluting stent implantation in high-angled (≥70°) bifurcation (HAB) and lower-angled (≤70°) bifurcation (LAB) lesion of unprotected left main coronary arteries. Methods: A prospective analysis of 488 patients with LMT stenosis (374 HAB and 114 LAB) in five high volume Asian centers after successful stenting in LMT was performed. LMT was treated with 5 strategies (single 195, mini-crush 116, culotte 89, T 47 cases, crush 32 cases, kissing 9). Results: At 5 years overall cardiac events of LAB (20.2%) were significantly lower than HAB (29.1%) (p=0.014).
Conclusion: Drug-eluting stent implantation in low-angled LMT bifurcation lesion showed lesser incidence of cardiac events (death, myocardial infarction, CABG and PCI) compared with high-angled LMT bifurcation lesion of unprotected left main coronary arteries at 5 years clinical follow-up.
