Conduction disorders after transcatheter aortic valve implantation: incidence, development and clinical significance

Transcatheter aortic valve implantation is gradually becoming the main method of treatment for high-grade aortic valve stenosis. As the indications for the procedure gradually expand and the incidence of severe aortic valve stenosis increases, given the aging population, the number of procedures performed will grow. Despite the minimally invasive nature of the procedure, it remains associated with some inherent complications. One of them is the conduction disturbances after transcatheter aortic valve implantation. Knowledge of the incidence, evolution over time and clinical significance of this type of complications of the procedure is of great importance for the proper management of patients. In recent years, various clinical trials have investigated complications of the conduction system after transcatheter aortic valve implantation. The purpose of this literature review is to discuss established data from the literature related to the incidence, evolution, and clinical significance, primarily of new-onset complete left bundle branch block or permanent pacemaker implantation after transcatheter aortic valve implantation.
