Ischemic mitral regurgitation (IMR) results from left ventricular remodelling after myocardial infarction and severely affects cardiovascular mortality and morbidity. Ischemic mitral valve regurgitation also represents a negative prognostic factor for long-term survival in patients undergoing surgical myocardial revascularization. While severe mitral regurgitation should always be corrected during a coronary artery bypass operation, the decision making is more difficult in patients with a moderate degree of regurgitation. In this review, we wish to highlight the negative impact of IMR on long-term survival and discuss the available evidence for surgical correction of IMR at the time of coronary revascularization.
缺血性二尖瓣反流(IMR)是心肌梗死后左心室重构的结果,严重影响心血管疾病的死亡率和发病率。缺血性二尖瓣反流也是接受外科心肌血运重建患者长期生存的不良预后因素。虽然在冠状动脉搭桥手术中严重二尖瓣反流应始终予以纠正,但对于中度反流患者,决策更为困难。在本综述中,我们希望强调IMR对长期生存的负面影响,并讨论在冠状动脉血运重建时外科纠正IMR的现有证据。
