| Abstract: | Background and Objectives: Transcatheter heart valve (THV) selection is challenging as self-expanding valves (SEVs) are associated with lower post-procedural mean aortic gradients, while balloon-expandable valves (BEVs) have lower rates of paravalvular leak (PVL) and permanent pacemaker implantation (PPI). We aimed to compare the 30-day and 1-year outcomes following Myval BEV (Meril Life Sciences, Vapi, Gujarat, India) and intra-annular Portico SEV (Abbott, St. Paul, MN, USA) implantation. Materials and Methods: We retrospectively analyzed the data from the all-comer TAVI registry of the University Medical Centre Ljubljana, Slovenia, from October 2017 to August 2023. Safety and efficacy outcomes following Myval BEV and Portico SEV implantation were compared overall and after propensity score matching. Results: Of the total 1152 THVs implanted, 97 patients (8%) received a Myval BEV and 47 (4%) a Portico SEV. After propensity score matching, there were no significant differences between the two patient cohorts regarding 30-day (Myval 0.0% vs. Portico 2.9%, p = 1.000) and 1-year mortality (Myval 0.0% vs. Portico 5.9%, p = 0.492). Likewise, the rates of new PPI, device failure (mean aortic gradient and more than mild PVL), and periprocedural in-hospital complications were comparable between the two groups. Conclusions: In this retrospective analysis of two intra-annular THVs, the Myval BEV was associated with comparable short- and mid-term outcomes as the Portico SEV. |
