Clinical significance of conduction disturbances after aortic valve intervention: current evidence

The occurrence of new conduction abnormalities that lead to the requirement for new permanent pacemaker implantation (PPI) has been reported to be the most frequent complication following transcatheter aortic valve implantation (TAVI). However, the reasons and clinical significance of TAVI-induced conduction disturbances and PPI are yet to be fully delineated. This review aims to evaluate the procedure- and patient-related factors that may contribute to the development of aberrant atrioventricular conduction following TAVI as well as its clinical consequences.
