Mitral insufficiency is unusual in patients with left atrial myxoma. A patient with myxoma of the left atrium presented with acute pulmonary edema due to ruptured chordae tendineae. Both lesions were unequivocally demonstrated by echocardiography, permitting emergency surgical correction to be undertaken without recourse to angiographic studies. Despite the rarity of acute mitral regurgitation due to rupture of chordae tendineae in association with left atrial myxoma, with only one such case previously reported, an etiologic relationship between the two disorders can be postulated. The association between the two thus should not be unexpected.
二尖瓣关闭不全在左心房黏液瘤患者中并不常见。一名左心房黏液瘤患者因腱索断裂出现急性肺水肿。超声心动图明确显示了这两种病变，使得在无需进行血管造影检查的情况下即可进行紧急手术矫正。尽管与左心房黏液瘤相关的腱索断裂导致急性二尖瓣反流很罕见，此前仅报道过一例，但可以推测这两种疾病之间存在病因学关系。因此，两者之间的关联不应出乎意料。
