Key result
PPI after TAVI shows ~35% one-year dependency and is linked to higher six-year mortality.
Why the study?
What is the incidence of pacemaker dependency, its predictors, and the impact of permanent pacemaker implantation on long-term mortality in patients after TAVI?
What is the incidence of pacemaker dependency, its predictors, and the impact of permanent pacemaker implantation on long-term mortality in patients after TAVI?
Permanent pacemaker implantation after TAVI carries a 33-36% dependency rate at one year and is associated with increased long-term mortality, with baseline RBBB serving as a key predictor for dependency.
PPI after TAVI warrants monitoring for dependency and mortality risk; extends observational data but leaves causality and practice change open.
Among patients receiving PPI after TAVI, PM dependency rates were about 33-36% at one year. Patients with a baseline RBBB undergoing PPI at day 0 or at day 1 when severe CDs persisted for 24 hours after TAVI, irrespective of baseline CDs, had a higher chance of being PM-dependent at follow-ups. Finally, PPI after TAVI was associated with increased six-year mortality.
