Higher PMIR with S3 versus XT warrants cautious implantation; retrospective data leaves open whether depth optimization reduces conduction risk.
Does TAVR with the SAPIEN 3 valve compared to the SAPIEN XT valve increase the pacemaker implantation rate in patients without prior pacemakers?
The increased pacemaker implantation rate observed with the SAPIEN 3 valve compared to the SAPIEN XT valve can be mitigated by aiming for a higher implantation height (aortic stent extension >70%).
