Dr Eric Van Belle (CHU Lille, France) presented the FRANCE-TAVI nationwide registry study, which attempted to determine the impact of transcatheter heart valve (THV) design (balloon-expandable [BE] or self-expanding [SE]) on the risk of paravalvular regurgitation (PVR), intrahospital mortality, and 2-year mortality [1]. The authors concluded that BE-THV had fewer complications. In this registry-based, multicentre, prospective, open, non-randomised study, 12,141 patients with native aortic stenosis received either BE-THV (n=8,038) or SE-THV (n=4,103). Follow-up was available for all patients (median 20 months, interquartile range 14-30). Co-primary outcomes of this study were the occurrence of ≥moderate PVR and/or in-hospital mortality, as well as 2-year all-cause mortality. For the presented matched-propensity analyses, 25 clinical, anatomical, and procedural variables, coupled with the d...
