Moderate to severe mitral regurgitation frequently accompanies severe aortic stenosis, affecting up to two-thirds of patients requiring aortic valve replacement. This combination may warrant double valve surgery, particularly when mitral regurgitation is severe, degenerative in nature, associated with left atrial dilation, chronic atrial fibrillation, or mitral annular calcium. However, management of mild to moderate mitral regurgitation alongside aortic stenosis remains controversial due to increased surgical risks and limited guideline evidence, which relies primarily on small studies and expert consensus. For patients unsuitable for open surgery, transcatheter aortic valve implantation offers a reasonable alternative strategy, with the potential that mitral regurgitation may improve, become better tolerated, or be addressed through staged transcatheter mitral interventions. This review examines surgical outcomes in combined aortic and mitral valve disease while exploring how transcatheter-based heart valve techniques can address this complex patient population, addressing a significant gap in current clinical guidance for managing multivalve disease.
