The Conundrum of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation.

Transcatheter aortic valve implantation (TAVI) has matured into the preferred treatment modality for patients with severe aortic stenosis at extreme or high risk for conventional surgery and a valuable alternative for those at intermediate risk in view of similar or superior clinical outcomes and decreased rates of periprocedural adverse events. In this context, it remains unclear whether other procedure-related events—including atrioventricular conduction disturbances that require permanent pacemaker (PPM) implantation—are of prognostic relevance.
