Why the study?
Conduction disease post-TAVR is frequent and permanent pacemaker placement is relatively common and associated with worse outcomes, but very late presenting complete heart block is not well characterized.
Highlights the occurrence of very late complete heart block post-TAVR and demonstrates the feasibility of His-bundle pacing in this population.
Raises awareness for delayed conduction block post-TAVR; hypothesis-generating for His-bundle pacing in this setting.
Transcatheter aortic valve replacement (TAVR) is a rapidly growing procedure. Conduction disease post-TAVR is frequent and routinely monitored for periprocedurally. Permanent pacemaker placement is relatively common and usually associated with worse outcomes post-TAVR. We report a case of very late presenting complete heart block post-TAVR treated with His-bundle pacing. Our case underscores the need for larger studies to further evaluate the utility of long-term cardiac monitoring post-TAVR and outcomes of His-bundle pacing in this population.
