Key result
Transcatheter aortic valve implantation is frequently complicated by conduction anomalies requiring permanent pacemaker implantation, with baseline right bundle branch block, self-expanding devices, and deeper implantation depth being the main predictors.
Why the study?
As TAVI expands to younger and lower-risk patients, conduction anomalies frequently occur due to the close proximity of the aortic valve to the conduction system.
What are the rates, predictors, and clinical impacts of permanent pacemaker implantation and conduction anomalies after transcatheter aortic valve implantation?

Alerts clinicians to key PPM predictors post-TAVI; leaves open prospective trials on modifiable factors.
What are the rates, predictors, and clinical impacts of permanent pacemaker implantation and conduction anomalies after transcatheter aortic valve implantation?
Despite advances in TAVI technology, conduction anomalies requiring permanent pacemaker implantation remain a significant complication driven by baseline RBBB, valve type, and implantation depth.
Russo et al. (2018) conducted a review in Severe symptomatic aortic stenosis. Transcatheter Aortic Valve Implantation (TAVI) was evaluated on Permanent pacemaker implantation (PPI) rate and predictors. Transcatheter aortic valve implantation is frequently complicated by conduction anomalies requiring permanent pacemaker implantation, with baseline right bundle branch block, self-expanding devices, and deeper implantation depth being the main predictors.
