We describe two patients with cardiac tumors in the left atrium, which by their association and histopathological lineage, are extremely rare. The clinical, echocardiographic and pathological findings were analysed. The first case was asymptomatic, but in the control studies of colon adenocarcinoma, an intracardiac mass was found by chest computed tomography (CT). A transesophageal 3D (TEE 3D) echocardiogram revealed a left atrial mass attached to the interatrial septum. The mass was surgically removed and histopathologic findings showed myxoma. The second had history of chronic intermittent diarrhea. A thoraco-abdominal CT showed a left atrial mass. The TEE 3D echocardiography reported an intracardiac mass attached to the roof of the left atrium. The mass was surgically removed and the histopathogical findings showed a myxoma, with dystrophic ossification and extramedullary hematopoiesis. TEE 3D echocardiography provides an acceptable morphological characterisation of intracardiac masses, with good correlation with surgery.
我们描述了两名左心房患有心脏肿瘤的患者，就其关联情况和组织病理学谱系而言，极为罕见。对临床、超声心动图及病理检查结果进行了分析。首例患者无症状，但在结肠腺癌的对照研究中，胸部计算机断层扫描（CT）发现了心脏内肿块。经食管三维（TEE 3D）超声心动图显示一个附着于房间隔的左心房肿块。该肿块经手术切除，组织病理学检查结果显示为黏液瘤。第二例患者有慢性间歇性腹泻病史。胸腹CT显示一个左心房肿块。TEE 3D超声心动图报告一个附着于左心房顶部的心脏内肿块。该肿块经手术切除，组织病理学检查结果显示为黏液瘤，伴有营养不良性骨化和髓外造血。TEE 3D超声心动图可为心脏内肿块提供可接受的形态学特征描述，与手术结果具有良好的相关性。
