Abstract

Atrial myxomas are the most common primary cardiac tumors. Typical complications include congestive heart failure, systemic emboli, or vasculitic type syndromes. Presented is a case of postpartum congestive heart failure in a 17-year-old girl. Echocardiography revealed a left atrial mass. Intraoperatively this mass was found to be extending into and occluding the left pulmonary veins. Left pulmonary infarction had occurred, and left pneumonectomy was required to completely remove the lesion. This case thus represents an unusual complication of left atrial myxoma.

摘要

心房黏液瘤是最常见的原发性心脏肿瘤。典型的并发症包括充血性心力衰竭、系统性栓塞或血管炎样综合征。本文报道了一名17岁女孩产后充血性心力衰竭的病例。超声心动图显示左心房有一肿块。术中发现该肿块延伸至左肺静脉并将其阻塞。已发生左肺梗死，需要进行左肺切除术以完全切除病变。因此，该病例代表了左心房黏液瘤一种不寻常的并发症。
