AIMS: Early data on the Edwards SAPIEN 3 valve (S3-THV) have shown low rates of paravalvular leaks and vascular complications but relatively high 30-day permanent pacemaker implantation (PPMI) rates. No direct comparisons on clinical outcomes including PPMI rates are available for the S3-THV and the Edwards SAPIEN XT (XT-THV). We aimed to compare the 30-day PPMI rates in patients treated with the two prostheses and to assess the interplay among valve type, depth of implantation and PPMI rate. METHODS AND RESULTS: Two hundred and nine patients treated by TAVI were considered. The S3-THV was associated with higher PPMI rates compared to the XT-THV, both overall and in subgroups matched for several predictors of PPMI. However, in the S3-THV group, 30-day PPMI was strictly associated with deep valve implantation, and PPMI risk of high-implanted S3-THVs was similar to that of the overall XT-THV matched group. No cases of significant paravalvular leak were observed in the S3-THV group. CONCLUSIONS: The S3-THV was associated with a higher incidence of PPMI compared to the XT-THV. In the S3-THV group, pacemaker implantation was strictly associated with deep valve implantation. An implantation technique involving higher initial placement of the central marker (from 0 to 3 mm above the base of the aortic cusps) and, as a consequence, higher final valve depth might help in preventing post-TAVI PPMI with the S3-THV, without affecting the risk of paravalvular leak.
