Aim: Absorb BVS™ (Abbott Vascular, Santa Monica, CA, USA) is the longest clinically available biodegradable stent (bioresorbablevascular scaffold, BVS). Despite promising results, pitfalls associated with treatment with this type of coronary implants haveemerged. This were the registries at first, some meta-analyses subsequently, the three-year results of the ABSORB II randomizedtrial in autumn 2016 that suggested an increased risk of thrombosis of the BVS stent compared with the newest-generation DES.The aim of our study was to evaluate the clinical outcomes of a real population of patients with implanted BVS with an emphasison the incidence of definite/probable BVS thrombosis.

Patients and methods: The group consisted of consecutive patients who had received an Absorb BVS implant at our centrebetween 09/2013 and 12/2015. As of 30 April 2017, we retrospectively evaluated, in collaboration with the Institute of Health Informationand Statistics of the Czech Republic, the incidence of the device-oriented composite endpoint (DOCE) and that of thepatient-oriented composite endpoint (POCE), with a particular focus on BVS thrombosis.

Results: During the follow-up period, a total of 210 Absorb BVSs were implanted in 178 patients during 196 PCIs. The medianfollow-up was 772 days. The indication for implantation was acute coronary syndrome in 47% of the cases and stable forms ofIHD in the remaining cases. At one year, the incidence of DOCE was 4.5%, with an estimated incidence at two years being 6.8% on the basis of Kaplan-Meier analysis. Death from cardiovascular causes occurred in 3.9% of the patients in the first year. A totalof six cases of definite and two cases of probable BVS thrombosis were encountered. The incidence of definite/probable BVSthrombosis thus reached 2.8% by 30 days and 3.9% by 1 year.

Conclusion: We present data on the use of Absorb BVS in real clinical practice of a single centre with a focus on BVS thrombosis.Our results confirm the concern about higher rates of this complication that, according to the data available so far, appears to bethe major and most serious problem in treating IHD with biodegradable stents of this type.
