Outcomes of three different new generation transcatheter aortic valve prostheses

Aims To evaluate outcomes of transfemoral transcatheter aortic valve implantation (TF‐TAVI) using three different new‐generation devices. Background Although new generation transcatheter aortic valves (TAVs) have demonstrated to improve procedural outcomes, to date few head‐to‐head comparisons are available among these devices. Methods This is a single center, retrospective study. From September 2014 to February 2018, 389 patients underwent elective TF‐TAVI for native, severe aortic stenosis using a new‐generation transcatheter aortic valve (TAV) with a preprocedural multi‐detector computed tomography assessment. Among these, 346 patients received an Edwards SAPIEN 3 (n = 134), Medtronic Evolut R (n = 111), or Boston ACURATE neo (n = 101) prosthesis. Differences in baseline clinical characteristics between groups were accounted using the propensity score weighting method. RESULTS The mean age for the entire study cohort was 81.4 ± 5.2 years while the Society of Thoracic Surgery predicted risk of mortality was 4.0 ± 2.5%. After propensity score weighting adjustment, TAVs did not differently impact on 30‐day all‐cause and cardiovascular mortality. Evolut R device showed an increased risk of permanent pacemaker implantation (PPI) after the procedure (8.3% for SAPIEN 3 vs. 16.7% for Evolut R vs. 2.1% for ACURATE neo, p
