N2 - Aims: We aimed to evaluate the relationship between CT-based annular perimeter oversizing and the incidence of paravalvular aortic regurgitation (PAR) and permanent pacemaker (PPM) implantation in patients treated with the new self-expanding CENTERA transcatheter heart valve (THV) for severe aortic stenosis. Methods and results: One hundred and ninety-eight patients in the CENTERA-EU trial were stratified a priori into four groups based on the perimeter oversizing (2.5-10%, 10-15%, 15-20% and >20%). PAR at 30 days was moderate or higher in 0.6% of patients. The frequency of PPM implantation was 4.9%. The mean perimeter oversizing was 16.2±5.6%. For patients with a perimeter oversizing >10%, an inverse relationship between oversizing and ≥mild PAR was observed (43.3% for 10-15% oversizing; 37.7%, 15-20%; 33.3%, >20%). No association between oversizing and effective orifice area was observed. The optimal cutoff value of perimeter oversizing for the prediction of ≥mild PAR was 15.9% (AUC 0.718, 95% CI: 0.576, 0.860). No annular ruptures were observed. Conclusions: The CENTERA THV appears to have a wide range of sizing tolerance. The degree of oversizing to mitigate PAR is relatively low compared to other self-expanding transcatheter devices. There appears to be no compromise between occurrence of PAR and PPM across this wide range of oversizing.
