Management of conduction abnormalities after TAVI. From ref.⁶ AF, atrial fibrillation; AV, atrioventricular; AVB, atrioventricular block; BBB, bundle branch block; ECG, electrocardiogram; EPS, electrophysiology study; HV, His-ventricular interval; LBBB, left bundle branch block; LVEF, left ventricular ejection fraction; PM, pacemaker; RBBB, right bundle branch block; TAVI, transcatheter aortic valve implantation. ^a24–48-h post-procedure. ^bTransient high-degree AVB, PR prolongation, or axis change. ^cHigh-risk parameters for high-degree AV block in patients with new-onset LBBB include AF, prolonged PR interval and LVEF < 40%. ^dAmbulatory continuous ECG monitoring for 7–30 days. ^eEPS with HV ≥ 70 ms may be considered positive for permanent pacing. ^fWith no further prolongation of QRS or PR during 48-h observation.
