A murmur of mitral regurgitation in patients with congestive heart failure after an acute myocardial infarction suggests a surgically correctable cause of the heart failure. Six patients who presented in this manner and who later underwent surgery have been evaluated by two-dimensional echocardiography (2DE). The underlying anatomical cause of the mitral regurgitation was correctly identified as papillary muscle rupture (2 cases), ruptured chordae tendineae (1 case) and papillary muscle fibrosis (3 cases). Two-dimensional echocardiography is useful in evaluating patients with congestive heart failure who develop a systolic murmur after acute infarction, as it can detect surgically correctable structural defects.

急性心肌梗死后出现充血性心力衰竭的患者出现二尖瓣反流杂音提示心力衰竭存在可通过手术纠正的病因。6例以这种方式就诊并随后接受手术的患者已通过二维超声心动图（2DE）进行了评估。二尖瓣反流的潜在解剖学原因被正确识别为乳头肌破裂（2例）、腱索断裂（1例）和乳头肌纤维化（3例）。二维超声心动图有助于评估急性梗死后出现收缩期杂音的充血性心力衰竭患者，因为它可以检测出可通过手术纠正的结构缺陷。
