The transcatheter aortic valve replacement (TAVR) procedure provides a way to treat severe aortic stenosis in the large population of patients who are not candidates for surgical aortic valve replacement. Mitral regurgitation is often concomitant to aortic stenosis in these patients due to the high pressure of the left ventricle and long-term damage to the mitral valve. Due to the proximity of the aortic valve to the mitral valve, TAVR can impact the functional status of the mitral valve by affecting left ventricular outlet obstruction and the mitral valve annular shape. As TAVR becomes increasingly prevalent to treat aortic stenosis, consideration into the impact of TAVR on mitral valve function is important in order determine whether patients will be able to undergo mitral valve repair or replacement, whether surgically or percutaneously. In this review, we seek to explore the effect of TAVR on the mitral annular geometry, mitral valve flow, and the impact of TAVR on the mitral valve in the presence of mitral annular calcification.
