Pacemaker need after TAVR: Still a conundrum

Seven percent of patients (with no history of intraventricular conduction abnormalities) experienced intraprocedural high-degree Atrioventricular (AV)/complete heart block. High-degree/complete heart block was persistent in 64% of patients who developed significant intraprocedural intraventricular conduction abnormalities. Ninety-seven percent of patients with persistent high-degree AV/complete block ultimately required pacemaker implantation.
