The prevalence of heart failure(HF) is increasing worldwide, and mitral regurgitation(MR) is a common manifestation in patients with end-stage HF. Currently, the indications for concomitant surgical intervention of significant preoperative MR during left ventricular assist device(LVAD) implantation are still controversial. Based on discussing the etiology, classification, and pathophysiology of functional MR in patients with end-stage HF, this paper reviews the relevant factors affecting the prognosis of such patients and the progress of research related to whether to perform mitral valve surgery to intervene in significant MR during LVAD implantation, to provide a further reference for clinical practice.
