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.
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).
At 5 years overall cardiac events of LAB (20.2%) were significantly lower than HAB (29.1%) (p=0.014).
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.
