缺血性二尖瓣返流是心肌梗死后左室重构的重要后果。超声心动图对缺血性二尖瓣返流的诊断和评估是判断其对预后的不良影响和制定合理治疗策略的关键。缺血性二尖瓣返流的超声心动图评估没有单一的方法:二尖瓣返流严重程度和LV功能障碍的标准超声心动图测量通过乳头肌位移评估和二尖瓣变形的定量指数进行补充。通过超声心动图了解二尖瓣几何形状的新方法的开发可能会提高对缺血性二尖瓣返流机制、临床轨迹和可修复性的理解。本文的在线版本(doi:10.1186/1476-7120-12-46)包含补充材料,可供授权用户使用。
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.
