Key result
Transcatheter aortic valve implantation remains frequently complicated by periprocedural conduction disturbances, such as new-onset left bundle branch block and new pacemaker implantation.
Why the study?
Periprocedural conduction disturbances remain frequent after TAVI with potentially deleterious consequences, necessitating new strategies to avoid and manage them as TAVI expands to low-risk populations.
What are the mechanisms, consequences, and management strategies for intraventricular conduction disturbances after TAVI?
What are the mechanisms, consequences, and management strategies for intraventricular conduction disturbances after TAVI?
Conduction disturbances such as LBBB and the need for permanent pacemakers remain significant concerns after TAVI, necessitating improved strategies for prevention and management as the procedure expands to lower-risk patients.
Post-TAVI conduction disturbances warrant close monitoring; leaves open optimal prevention and management strategies.
Despite significant improvements in transcatheter aortic valve implantation (TAVI) outcomes, periprocedural conduction disturbances, such as new-onset left bundle branch block (LBBB) and new pacemaker implantation (PMI), remain relatively frequent concerns. The development of periprocedural conduction disturbances can be explained by the proximity between the aortic valve and the conduction system. Although prior studies reported heterogeneity in PMI rates after TAVI, current evidence supports the potentially deleterious consequence of LBBB and PMI, and several predisposing factors have been reported. Therefore, new strategies to avoid conduction disturbances and to improve their management are required, particularly with the current trend to expand TAVI to a low-risk population.

Lin et al. (2020) conducted a review in Periprocedural conduction disturbances after TAVI. Transcatheter Aortic Valve Implantation (TAVI) was evaluated. Transcatheter aortic valve implantation remains frequently complicated by periprocedural conduction disturbances, such as new-onset left bundle branch block and new pacemaker implantation.
