Surgical and transcatheter tricuspid valve interventions carry a significant risk of new conduction disturbances and permanent pacemaker implantation due to their proximity to the conduction system.
Understanding the atrioventricular conduction axis and involving electrophysiologists in the multidisciplinary heart team is crucial to anticipate and manage conduction complications associated with tricuspid valve interventions.
Increasing recognition of the clinical impact of isolated tricuspid regurgitation has led to rapid expansion of surgical and transcatheter tricuspid valve interventions. Given the close anatomic relationship between the tricuspid valve and the atrioventricular conduction system, both surgical and transcatheter approaches carry a significant risk of new conduction disturbances and permanent pacemaker implantation. A three-dimensional understanding of the atrioventricular conduction axis is essential to anticipate and mitigate these complications. This review provides a comprehensive overview of conduction system anatomy and physiology in the context of tricuspid valve interventions, highlighting the mechanisms underlying procedure-related conduction abnormalities. We also discuss contemporary management strategies, including approaches to pre-existing transvalvular leads, valve-sparing pacing alternatives, and the evolving role of electrophysiologists within the multidisciplinary heart team.
Tang et al. (Sun,) conducted a review in Tricuspid regurgitation. Surgical and transcatheter tricuspid valve interventions was evaluated. Surgical and transcatheter tricuspid valve interventions carry a significant risk of new conduction disturbances and permanent pacemaker implantation due to their proximity to the conduction system.
