percutaneous coronary intervention with absorb biodegradable vascular scaffold in patients with left anterior descending artery disease

Abstract

Aim. The article evaluates 30-day results of percutaneous coronary intervention (PCI) with ABSORB biodegradable vascular scaffold (BVS) implanted in the case of stenosis of the left anterior descending (LAD) coronary artery in patients with stable angina.
Methods. 64 patients with significant (≥ 70%) LAD disease were included in the study. At 30 days, scaffold thrombosis and major adverse cardiovascular events (all-cause mortality, myocardial infarction, stroke, target vessel revascularization) were evaluated. The indicator of successful percutaneous coronary intervention (residual stenosis ≤20% in the presence of counterpulsation corresponding to TIMI 3rd Grade and in the absence of significant in-patient clinical complications) and successful intervention assessed by clinical criteria (successful percutaneous coronary intervention alongside with a decrease in objective and subjective symptoms of myocardial ischemia, or their complete disappearance) were also analyzed.
Results. Mean age of patients was 61.6±8.5 years, with males accounting for 64%; 33% had earlier MI, 14% – diabetes mellitus. Mean left ventricular ejection fraction was 61.3±6.8%. Left anterior descending artery disease was presented in 89% of patients with SYNTAX Score 6.6±2.2. Mean number of implanted stents was 1.2±0.4, with mean length of the stented segment equal to18.7±1.8 mm and mean diameter 3.2±0.3 mm. At 30-day follow-up, the success of intervention assessed by clinical criteria amounted to 96.9% (n=62); that of myocardial infarction 3.1% (n=2); stent thrombosis 1.56% (n=1); repeated revascularization 1.56% (n=1); major adverse cardiovascular events (MACE) 3.1%.
Conclusion. The implantation of everolimus-eluting BVS for LAD stenosis demonstrates satisfactory results at 30-day follow-up.
