How to predict conduction disturbances after transcatheter aortic valve replacement.

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.
