Abstract
Despite the improvement in the incidence of periprocedural complications associated with transcatheter aortic valve replacement (TAVR), conduction disturbances remain the most frequent complication of TAVR procedures. Studies have demonstrated worse outcomes in patients with new‐onset left bundle branch block and complete heart block requiring permanent pacemaker implantation after TAVR. Conduction disturbances occur as a consequence of direct mechanical injury to the conduction system during the procedure. There are well‐described associated risk factors for the development of conduction disturbances. This chapter provides an overview of incidence, predictors, and clinical outcomes and reviews the new implantation techniques introduced to decrease the risk and potential deleterious effects of the conduction disturbances associated with TAVR. This is important as TAVR indications are expanding to younger and lower‐risk populations.
