Abstract
Aortic stenosis is the most common valvular heart disease in industrialized countries and the most common cause of left ventricular outflow tract (LVOT) obstruction. Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement for intermediate to high-risk surgical candidates with symptomatic severe aortic stenosis. Conduction system abnormalities, including atrioventricular (AV) and intraventricular (IV) block, are the most common complication of TAVR. In this review, we aim to explore the anatomical issues relevant to atrioventricular block, the relevant clinical and procedural aspects, and the management and long-term implications of AV and IV block.
