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.

At least one parameter between LVEF or MTG over 40 predicts a good prognosis for TAVI patients at mid-term follow-up, whereas those with both left ventricular dysfunction and low mean aortic pressure gradient are at high risk of all-cause death after TAVI.
