The authors report a case of rhabdomyoma of the right ventricular cavity with outlet obstruction in a three-months old infant. The diagnosis was established by echocardiography. Bidimensional echocardiography study showed a polypoid tumor of the right ventricle. During the systole it was projected through the pulmonary valve, obstructing part of it. The Doppler study showed an important gradient between the right ventricle and the pulmonary artery. The resection was performed with success. The diagnosis of cardiac rhabdomyoma was made by microscopic study. It is emphasized the importance of the echocardiographic study in an infant with oligosymptomatic cardiac murmurs.
作者报告了一例3个月大婴儿右心室腔横纹肌瘤伴流出道梗阻的病例。诊断通过超声心动图确定。二维超声心动图检查显示右心室有一个息肉样肿瘤。在收缩期，肿瘤经肺动脉瓣突出，阻塞了部分瓣膜。多普勒检查显示右心室和肺动脉之间存在显著压差。手术切除成功。通过显微镜检查确诊为心脏横纹肌瘤。强调了超声心动图检查在有轻度症状性心脏杂音的婴儿中的重要性。
