Acute ischemic events are frequent after primary coronary stenting

All-comer treatment with bioresorbable vascular scaffold

BACKGROUND

Bioresorbable vascular scaffolds (BVS) could overcome drug-eluting stents (DES) drawbacks connected with their permanent presence in the vessel wall. Studies exploring the clinical use of BVS are limited to the patients presenting with noncomplex, short and stable lesions. There are no prospective and randomized studies available in all-comer patients.

METHODS AND RESULTS

We analyzed 31 patients, who received at least one BVS (Absorb(™)) between September 1, 2012 and November 1, 2014. Median follow-up period was 424 days. In one (3.2%) patient, we performed a target vessel revascularization (TVR). The death rate was 6.5%. One (3.2%) patient, who received both BVS and a bare metal stent (BMS), died of an acute stent thrombosis 8 days after the initial procedure. One (3.2%) patient died of a non-cardiac death. We did not encounter any target lesion revascularization (TLR) or myocardial infarction (MI). The major adverse cardiac events (MACE) rate was 3.2%.

CONCLUSIONS

Implantation of BVS is a safe treatment option. Lesions should be carefully selected and prepared before BVS implantation. We need more data about the safety of BVS and BMS overlapping.
