OBJECTIVES: The aim of this study was to assess prospectively the effectiveness and safety profile of distal left main stem (LMS) stenosis treatment with dedicated bifurcation paclitaxel-eluting stent BiOSS Expert®. BACKGROUND: Angioplasty of distal LMS stenosis is always a high-risk procedure, and optimal treatment is uncertain. METHODS: This was a prospective international 2-center study, which enrolled patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) or stable angina with distal left main stenosis. All patients were treated with the dedicated bifurcation stent BiOSS Expert®. Provisional T-stenting was the obligatory strategy. Angiographic control was performed after 12 months. The primary end-point was cumulative rate of death, myocardial infarction (MI), and target lesion revascularization (TLR) at 12 months. Angiographic end-points included late lumen loss, percent diameter stenosis, and binary restenosis rate. RESULTS: A total of 54 patients with distal LMS stenosis were enrolled. Seven patients (13%) were enrolled during NSTE-ACS, 77.8% were hypertensive, 27.8% were diabetic, 51.9% had previous MI, 53.7% underwent prior percutaneous coronary intervention, and 16.7% coronary artery bypass graft. The mean SYNTAX score was 21.52 ± 6.50. The device success rate was 100%. The mean BiOSS Expert stent parameters were as follows: 4.07 ± 0.26 mm × 3.36 ± 0.26 mm × 16.61 ± 1.72 mm and in side branch the other stent (classical drug-eluting stent) was implanted in 25.9% of cases. The overall TLR was 9.3%. There were no death, stent thrombosis, or acute MI. In the univariate regression analysis, the only factor associated with higher risk for TLR was the SYNTAX score value. CONCLUSIONS: The dedicated bifurcation stent BiOSS Expert® proved to be a feasible device, with promising safety and long-term clinical effectiveness in the treatment of distal LMS stenosis.
