Incidence, Predictors and Prognosis of Pacemaker Implantation after Transcatheter Aortic Valve Implantation versus Surgical Aortic Valve Replacement: A Prospective Cohort Study.

Key Result

Transcatheter aortic valve implantation has a higher risk of permanent pacemaker implantation than surgical replacement, largely due to procedural and anatomical factors.

Key Points

The study aims to compare the incidence, predictors, and outcomes of pacemaker implantation following transcatheter aortic valve implantation and surgical aortic valve replacement.
Prospective cohort design
Comparison of pacemaker implantation incidence after both procedures
Evaluation of pre procedural imaging integration for risk assessment
Transcatheter aortic valve implantation presents a higher risk of pacemaker implantation than surgical replacement
Procedural and anatomical factors significantly contribute to this increased risk
Improved pre procedural imaging enhances risk stratification and planning.

Structured PICO

Does transcatheter aortic valve implantation increase the risk of permanent pacemaker implantation compared to surgical aortic valve replacement?

Population

Patients undergoing aortic valve replacement

Intervention

Transcatheter aortic valve implantation

Comparator

Surgical aortic valve replacement

Outcome

Incidence, predictors and prognosis of permanent pacemaker implantation and conduction disturbancessafety

Transcatheter aortic valve implantation carries a higher risk of conduction disturbances and permanent pacemaker implantation compared to surgical replacement, highlighting the potential value of detailed pre-procedural imaging for risk stratification.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Transcatheter aortic valve implantation is associated with a higher risk of conduction disturbances and permanent pacemaker implantation than surgical replacement, driven largely by procedural and anatomical factors. Integration of detailed pre procedural imaging may improve risk stratification and procedural planning.
