Functional mitral regurgitation is a common finding among heart failure patients with ischemic and non-ischemic dilated cardiomyopathies. The presence of moderate or severe mitral regurgitation is associated with higher morbidity and mortality. Heart failure patients meeting electrocardiogram and left ventricle function criteria are good candidates for cardiac resynchronization therapy, which may reduce the degree of functional mitral regurgitation in the short and long term, specifically targeting myocardial dyssynchrony and inducing left ventricle reverse remodeling. In this article, we analyze data from the literature about predictors of mitral regurgitation improvement after cardiac resynchronization therapy implantation.
功能性二尖瓣反流在患有缺血性和非缺血性扩张型心肌病的心力衰竭患者中很常见。中度或重度二尖瓣反流的存在与更高的发病率和死亡率相关。符合心电图和左心室功能标准的心力衰竭患者是心脏再同步治疗的良好候选者，这种治疗可能在短期和长期内降低功能性二尖瓣反流的程度，特别针对心肌不同步并诱导左心室逆向重构。在本文中，我们分析了文献中关于心脏再同步治疗植入后二尖瓣反流改善预测因素的数据。
