Aims: Despite the use of rotational atherectomy (RA) in interventional cardiology for over three decades, data regarding factors affecting the clinical outcomes of the RA procedure remain scarce. The aim of the present study was to describe the contemporary use and outcomes of RA in Europe.
Methods and results: We conducted, for the first time, a prospective international registry in 8 European countries and 19 centres and included patients treated by percutaneous coronary intervention with RA. Between October 2016 and July 2018, 966 patients with complete data were recruited. Mean age was 74.5 years, 72.4% were male and 43.4% had diabetes. Initial presentation was an acute coronary syndrome (ACS) for 25.1% of the patients. Clinical success was observed in 91.9% of the procedures. The rate of in-hospital major adverse cardiac events (MACE) – defined as cardiovascular death, myocardial infarction, target lesion revascularisation, stroke and coronary artery bypass grafting – was 4.7%. At one year, the rate of MACE was 13.2%. Factors independently associated with the occurrence of MACE at one year were female gender, renal failure, ACS at admission, depressed left ventricular ejection fraction (LVEF) and presence of a significant left main coronary artery (LMCA) lesion.
Conclusions: Despite the high level of complexity of the studied population, RA turned out to be an effective procedure with a low rate of in-hospital complications and demonstrated good immediate and midterm results.
