Cardiac myxomas, though typically benign and asymptomatic, can rarely present with acute cardiovascular compromise. We report a case of a left atrial myxoma presenting as acute pulmonary edema in a patient with prior normal cardiac imaging. A 55-year-old male, with a history of thrombolyzed myocardial infarction and normal coronary angiography and echocardiography five years earlier, was admitted with acute dyspnea and pulmonary edema. Bedside transthoracic echocardiography (TTE) revealed a left atrial mass causing severe mitral inflow obstruction. Emergency surgical excision was performed, and the mass was submitted for histopathological analysis. Histology confirmed cardiac myxoma. The procedure and recovery were uneventful, and follow-up at one month confirmed no recurrence. This case illustrates the potential for cardiac myxoma to manifest suddenly with life-threatening symptoms, even after previously normal investigations. Echocardiography remains pivotal in diagnosing intracardiac masses and guiding timely intervention.
心脏黏液瘤虽然通常为良性且无症状，但很少会导致急性心血管功能障碍。我们报告一例左心房黏液瘤病例，该患者既往心脏影像学检查正常，此次表现为急性肺水肿。一名55岁男性，有五年前溶栓治疗的心肌梗死病史，当时冠状动脉造影和超声心动图检查均正常，因急性呼吸困难和肺水肿入院。床旁经胸超声心动图（TTE）显示左心房有一肿块，导致严重的二尖瓣血流梗阻。遂行急诊手术切除，并将肿块送去做组织病理学分析。组织学检查确诊为心脏黏液瘤。手术过程顺利，恢复良好，术后一个月随访未发现复发。该病例表明，即使之前检查正常，心脏黏液瘤仍有可能突然出现危及生命的症状。超声心动图在诊断心内肿块和指导及时干预方面仍然至关重要。
