A 69-year-old man developed a rupture of the papillary muscle on the fifth day of acute posterior myocardial infarction. The two-dimensional echocardiographic features of ruptured papillary muscle included (1) mobile mass of echos attached to normal chordae tendineae in the left ventricle, (2) absent tip of papillary muscle, and (3) mitral valve prolapse. Noninvasive, two-dimensional echocardiography can reveal correct diagnosis of ruptured papillary muscle suspected clinically.
一名69岁男性在急性后壁心肌梗死第5天发生乳头肌破裂。乳头肌破裂的二维超声心动图特征包括：（1）附着于左心室正常腱索的可移动回声团块；（2）乳头肌尖端缺失；（3）二尖瓣脱垂。无创性二维超声心动图能够对临床上怀疑的乳头肌破裂做出正确诊断。
