本研究的目的是明确经食管超声心动图对大量具有这一罕见发现的患者的右心房肿瘤诊断的贡献。经食管超声心动图（TEE）已被发现对于评估心内肿块患者很有价值，并且在评估左心肿块方面优于经胸超声心动图（TTE）。 1989 年至 1993 年间，23 名患有其他部位已知肿瘤或在 TTE 上检测到右心房肿块的患者接受了 TEE 评估。 TEE 研究是在无创心脏病学实验室进行的。所有患者均使用 5 MHz 双平面或全平面传感器进行研究。评估右心房任何肿块的存在、特征、范围和附着，以及这些肿块延伸至大血管或其他心室的情况。没有出现并发症。六名患者患有原发性右心房肿瘤。 10 名患者的肿瘤通过下腔静脉到达右心房。 7名患者患有继发性恶性肿瘤。 TEE 证实了 TTE 未检测到的三个肿瘤。此外，TEE 还提供了 TTE 上没有的 16 个额外发现。综上所述，TEE对右心房肿瘤的评估优于TTE。对于右心房肿瘤患者，即使已经通过 TTE 证实了这些肿瘤，也应考虑 TEE。
The purpose of this study was to define the contribution of transesophageal echocardiography to the diagnosis of right atrial tumors in a large series of patients with this rare finding. Transesophageal echocardiography (TEE) has been found to be valuable in evaluating patients with intracardiac masses and has been shown to be superior to transthoracic echocardiography (TTE) in evaluating left heart masses. Between 1989 and 1993, 23 patients with either known tumors elsewhere or right atrial masses that were detected on TTE were evaluated with TEE. TEE studies were performed in the noninvasive cardiology laboratory. All patients were studied with 5 MHz biplane or omniplane transducers. The right atrium was evaluated for the presence, characteristics, extent, and attachment of any masses and for extension of these masses into the great vessels or other cardiac chambers. No complications occurred. Six patients had primary right atrial tumors. In 10 patients the tumors reached the right atrium via the inferior vena cava. Seven patients had malignant secondary tumors. TEE demonstrated three tumors not detected by TTE. Furthermore TEE provided 16 additional findings not seen on TTE. In conclusion, TEE is superior to TTE in the evaluation of right atrial tumors. TEE should be considered in patients with right atrial tumors even when these tumors have been demonstrated with TTE.
