Algorithm for post-TAVR high-degree AV block discharge risk stratification. Delayed discharge strategy: discharge on POD 3-4 for patients with new persistent LBBB and POD 4 for patients with pre-TAVR RBBB. The duration of ambulatory monitoring should be at least 14 days. ∗ In this low-risk population, post-TAVR EPS with HV <65 ms had a 100% sensitivity in ruling out HDAVB.
