title: Immediate and long-term clinical performance of bioresorbable vascular scaffolds in a real world population.
abstract: BACKGROUND
  The aim of this study was to evaluate the safety and efficacy of bioresorbable vascular scaffolds (BVS) in terms of acute success and long-term clinical events in a real world population according to the most updated technical recommendations.
  
  
  METHODS
  Perspective, single-center registry involving symptomatic patients treated with BVS from February 2013 to January 2016. Primary end-point was the occurrence of MACCEs at one year: death, target vessel related myocardial infarction, target vessel revascularization, stroke, major bleeding. Secondary endpoints were acute device and procedural clinical success, and occurrence of MACCEs at long-term follow-up.
  
  
  RESULTS
  In total, 112 patients were treated on 173 lesions. Average age was 55.53±12.4 years and acute coronary syndrome was the admission diagnosis for 79.5% patients. Nine patients presented cardiac allograft vasculopathy after cardiac transplantation. Multi-vessel disease was treated in 50% of cases. Predilatation and post-dilatation were performed respectively in 96% and 88.4% of lesions. Intravascular imaging was used in 41 patients (37%). Angiographic success rate and procedural success rate were 100% and 97.3% respectively. Clinical follow-up was completed in 100 patients with an average follow-up of 10.5±8.3 months. Including peri-procedural and in-hospital MACCEs, target vessel failure was noticed in 7% of patients in the first year of follow up and in 11% of patients at long-term follow-up. Two cases of target lesion revascularization occurred 25 and 26 months after the index procedure. No cases of definite stent thrombosis were reported.
  
  
  CONCLUSIONS
  Strict adherence to expert recommendation for BVS placement may minimize device related peri-procedural and mid-to-long term MACCEs in a real world population.
