Incidence of permanent pacemaker implantation (PPMI)safety
Higher pacemaker rates with the SAPIEN 3 valve compared to the XT valve are driven by deep valve implantation, suggesting that a higher implantation technique may prevent this complication without increasing paravalvular leak.
Resumen
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.
