An asymptomatic patient was discovered to have a large right atrial myxoma by transthoracic echocardiography. Preoperative considerations included the possibility of satellite lesions, left atrial origin, and a question of tricuspid valve involvement. Subsequent operative transesophageal echocardiography demonstrated single-stalk attachment in the right atrial septal wall and no satellite lesions. Doppler and color flow examination immediately following tumor removal aided in the decision not to perform tricuspid annuloplasty as there was no significant tricuspid regurgitation. The combined use of transthoracic and transesophageal echocardiography with Doppler and color flow imaging aids in the preoperative and intraoperative diagnosis and surgical management of right atrial tumors.
一名无症状患者经经胸超声心动图检查发现右心房有一个巨大黏液瘤。术前考虑因素包括存在卫星病灶的可能性、左心房起源以及三尖瓣受累问题。随后的术中经食管超声心动图显示肿瘤单蒂附着于右心房间隔壁，且无卫星病灶。肿瘤切除后立即进行的多普勒和彩色血流检查有助于做出不进行三尖瓣环成形术的决定，因为当时没有明显的三尖瓣反流。经胸和经食管超声心动图联合多普勒和彩色血流成像有助于右心房肿瘤的术前和术中诊断及手术管理。
