Hepatoma has a tendency to spread into the venous system, but intracavitary cardiac extension or metastasis of hepatocellular carcinoma is an uncommon form of cardiac malignancy. When the carcinoma grows from the hepatic vein into the right atrium, the right atrial tumor thrombis may hinder the blood flow. Therefore, these patients have the risk of sudden death. In the past, antemortem diagnosis of right atrial tumor thrombi in patients with primary hepatocellular carcinoma was difficult. But, echocardiography allowed easy detection of the intracardiac tumor thrombi. We describe two cases of hepatocellular carcinoma with right atrial tumor thrombi. In these cases, the right atrial tumor thrombi was detected by two-dimensional echocardiography. Recently, successful surgical removal of the right atrial tumor thrombi are reported in several cases. We advocate performing echocardiographic examination in patients with hepatoma who have cardiac symptoms and signs.
肝癌有向静脉系统扩散的倾向，但肝细胞癌的腔内心脏扩展或转移是一种罕见的心脏恶性肿瘤形式。当癌从肝静脉长入右心房时，右心房肿瘤血栓可能会阻碍血流。因此，这些患者有猝死的风险。过去，原发性肝细胞癌患者的右心房肿瘤血栓生前诊断困难。但是，超声心动图可以轻松检测出心脏内的肿瘤血栓。我们描述了两例伴有右心房肿瘤血栓的肝细胞癌病例。在这些病例中，二维超声心动图检测到了右心房肿瘤血栓。最近，有几例报道成功手术切除了右心房肿瘤血栓。我们主张对有心脏症状和体征的肝癌患者进行超声心动图检查。
