AbstractChronic aortic regurgitation (AR) frequently leads to significant downstream changes to the left ventricle and pulmonary vasculature; these structural and physiologic changes result in lower- than expected patient survival. Progressive, uncorrected AR can lead to left ventricle dilation and subsequent mitral valve leaflet tethering, as well as mitral annular dilation, resulting in secondary mitral regurgitation (MR) in up to 45% of patients. Surgical aortic valve replacement (AVR) improves secondary MR in most patients, but survival is significantly lower in those patients who do not show improvement in MR after AVR. Thus, there is considerable debate on whether the mitral valve should be intervened upon at the time of the AVR. In this review, the authors address the long-term outlook for patients with chronic AR and concurrent MR. The authors also review the available evidence on concomitant mitral valve surgery in patients undergoing AVR for AR. Lastly, this narrative review examines the recent advances in transcatheter mitral valve repair and replacement, and explores the potential role of transcatheter mitral therapies in patients with secondary MR due to AR.Copyright © 2021 Elsevier Inc.
