Intracavitary ventricular tumors were found in 3 male patients (newborn, and 18 and 23 years old) by 2-D echocardiography (metastasis of an osteogenic sarcoma in the right ventricle, teratoma embryonale growing from the retroperitoneum into the right ventricle, rhabdomyoma of the left ventricle). They all showed a uniform echo pattern and two of them were pedunculated. Wall motility, valves and cardiac dimensions were normal. In each case diagnosis was confirmed intraoperatively or at autopsy. Clinically the metastasis of the osteogenic sarcoma presented as obstruction of the superior vena cava, whereas the teratoma embryonale imitated tricuspid valve disease. The rhabdomyoma caused a systolic murmur and severe postpartal sinus bradycardia. It was successfully removed on the basis of echocardiography alone. 2-D echocardiography is a reliable, noninvasive diagnostic tool for evaluation of intracavitary, ventricular tumors.
通过二维超声心动图在3例男性患者（新生儿、18岁和23岁）中发现了心腔内室性肿瘤（右心室骨肉瘤转移、从腹膜后生长至右心室的胚胎性畸胎瘤、左心室横纹肌瘤）。它们均表现为均匀的回声模式，其中2例有蒂。室壁运动、瓣膜及心脏大小均正常。每例均经手术或尸检确诊。临床上，骨肉瘤转移表现为上腔静脉梗阻，而胚胎性畸胎瘤类似三尖瓣疾病。横纹肌瘤引起收缩期杂音和产后严重窦性心动过缓。仅根据超声心动图就成功将其切除。二维超声心动图是评估心腔内室性肿瘤的可靠的无创诊断工具。
