First Bioresorbable Vascular Scaffold Implantation in Patients with Acute Coronary Syndrome in the Republic of Macedonia.

Abstract

The term acute coronary syndrome (ACS) refers to any group of clinical symptoms compatible with acute myocardial ischemia. These high-risk manifestations of coronary atherosclerosis are important causes of the use of emergency medical care and hospitalization. We evaluated the feasibility and the acute performance of the everolimus-eluting bioresorbable vascular scaffolds (BVS) for the treatment of patients presenting with ACS. The present investigation was a prospective, single-centre study. Clinical outcomes were reported at the 30-day, 6-month, 1 year and 2 years follow-up. The procedural success was 100.0%. After the BVS implantation a TIMI flow 3 was achieved in all 15 patients and the postprocedure percentage diameter stenosis was 16.4 ± 8.6%. No patients had angiographically visible residual thrombus at the end of the procedure. Optical coherence tomography (OCT) analysis was performed in 8 patients (53.3%) and showed that the post-procedure mean lumen area was 7.86 ± 1.81 mm(2), minimum lumen area 5.51 ± 1.58 mm(2). At the 30-day, 6-month, 1 year (15 patients) and 2 years follow-up (5 patients) target-lesion failure rate was 0%. Non-target vessel revascularization and target vessel myocardial infarction were not reported. No cases of cardiac death or scaffold thrombosis were observed. BVS implantation in patients presenting with ACS appeared feasible, with high rate of final TIMI-flow 3 and good scaffold apposition.
