Key result
The mean incidence of permanent pacemaker implantation following TAVI was 14.2%, compared to 7.0% following conventional surgical aortic valve replacement.
Why the study?
What is the incidence and what are the predictors of postoperative permanent pacemaker implantation in patients undergoing TAVI compared to surgical AVR?
Population

TAVI doubles PPI risk versus SAVR; warrants pre-TAVI conduction assessment and supports prosthesis-specific trials to refine patient selection.

What is the incidence and what are the predictors of postoperative permanent pacemaker implantation in patients undergoing TAVI compared to surgical AVR?
Absolute Event Rate: 14.2% vs 7%
TAVI is associated with a higher incidence of permanent pacemaker implantation compared to surgical AVR, with the risk being strongly influenced by the type of prosthesis used and pre-existing conduction system dysfunction.
Bates et al. (2010) conducted a systematic review in Symptomatic calcific aortic stenosis. Trans-catheter aortic valve implantation (TAVI) vs. Conventional surgical aortic valve replacement (AVR) was evaluated on Incidence of postoperative permanent pacemaker (PPM) implantation. The mean incidence of permanent pacemaker implantation following TAVI was 14.2%, compared to 7.0% following conventional surgical aortic valve replacement.
