Key result
Pre-existing right bundle branch block, membranous septum length, and valve implantation depth are key predictors of conduction disturbances and permanent pacemaker implantation after transcatheter aortic valve replacement.
Why the study?
Despite known predictors and valve refinements, rates of post-TAVI conduction disturbances remain high, creating a need for new strategies to reduce permanent pacemaker implantations.
What are the incidence, predictive factors, and clinical implications of conduction disturbances after transcatheter aortic valve replacement?

This review highlights the ongoing challenge of conduction disturbances post-TAVI and emphasizes the need for new strategies to reduce permanent pacemaker implantations.
Persistent conduction disturbance rates after TAVI require vigilant monitoring; leaves open optimal prevention via valve design and risk tools.
Transcatheter aortic valve replacement (TAVI) has evolved into the gold standard management option for high-risk patients with severe aortic stenosis. Despite identifying procedural, electrocardiographic, and clinical predictors of important post-procedural conduction disturbances (left bundle branch block and high-degree atrioventricular block) and despite continuous technological refinement of transcatheter aortic valves, the rate of post-procedural conduction disturbance remains high and challenging to manage. New strategies are required to reduce the overall rate of post-procedural permanent pacemaker implantations. In this article, we will review the incidence, predictive factors, and clinical implications of conduction disturbances after TAVI.

Novelli et al. (2023) conducted a review in severe aortic stenosis. Transcatheter aortic valve replacement (TAVI) was evaluated. Pre-existing right bundle branch block, membranous septum length, and valve implantation depth are key predictors of conduction disturbances and permanent pacemaker implantation after transcatheter aortic valve replacement.
