Ischemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Echocardiographic diagnosis and assessment of ischemic mitral regurgitation are critical to gauge its adverse effects on prognosis and to attempt to tailor rational treatment strategy. There is no single approach to the echocardiographic assessment of ischemic mitral regurgitation: standard echocardiographic measures of mitral regurgitation severity and of LV dysfunction are complemented by assessments of displacement of the papillary muscles and quantitative indices of mitral valve deformation. Development of novel approaches to understand mitral valve geometry by echocardiography may improve understanding of the mechanism, clinical trajectory, and reparability of ischemic mitral regurgitation.
缺血性二尖瓣反流是心肌梗死后左心室重构的重要后果。超声心动图对缺血性二尖瓣反流的诊断和评估对于衡量其对预后的不良影响以及尝试制定合理的治疗策略至关重要。对于缺血性二尖瓣反流的超声心动图评估没有单一的方法:二尖瓣反流严重程度和左心室功能障碍的标准超声心动图测量方法,辅以对乳头肌移位和二尖瓣变形定量指标的评估。通过超声心动图开发新的方法来了解二尖瓣几何形状,可能会增进对缺血性二尖瓣反流的机制、临床病程和可修复性的理解。
