Impact of untreated mild-to-moderate mitral regurgitation at the time of isolated aortic valve replacement on late adverse outcomes☆

Abstract

Despite the significant reduction after isolated AVR, preoperative mild-to-moderate MR is an independent risk factor impacting long-term functional outcome. Our results suggested that the concomitant mitral valve surgery for mild-to-moderate MR is warranted, especially in patients with reduced left ventricular function.
