Abstract 16821: Comparison of 4 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
Background: The use of drug-eluting stent (DES) is associated with excellent clinical results in left main bifurcation lesions. However, there is limited angiographic and clinical follow-up data after single DES implantation with final kissing inflation (FKI) for unprotected left main bifurcation lesions.
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 4 years overall cardiac events of LAB (18.4%) were significantly lower than HAB (27.0%) (p=0.012).
Conclusions: 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 4 years clinical follow-up.
