Recently, real-time 3-dimensional transesophageal echocardiography (3D-TEE) was introduced to allow online acquisition, rendering, and provision of accurate information on cardiac structures. We report our initial experience of this modality. The 1st patient had mitral valve insufficiency; mitral valve prolapse of the P2 segment was clearly visualized by preoperative 3D-TEE. The 2nd patient had severe aortic stenosis, in whom 3D-TEE demonstrated fusion of the non- and right-coronary cusps. The 3rd patient had ventricular septal defect (perimembranous type), and 3D-TEE precisely demonstrated the size, shape, and location of the defect. The diagnoses were confirmed intraoperatively in all the patients. In conclusion, real-time 3D-TEE was useful for assessing the anatomical features of heart structures, enabling us to perform safer operations.
最近，实时三维经食管超声心动图（3D-TEE）被引入，以实现心脏结构信息的在线采集、呈现和提供。我们报告了我们对这种检查方式的初步经验。首例患者患有二尖瓣关闭不全；术前3D-TEE清晰显示了P2段二尖瓣脱垂。第二例患者患有严重主动脉瓣狭窄，3D-TEE显示无冠瓣和右冠瓣融合。第三例患者患有室间隔缺损（膜周型），3D-TEE精确显示了缺损的大小、形状和位置。所有患者的诊断均在术中得到证实。总之，实时3D-TEE有助于评估心脏结构的解剖特征，使我们能够进行更安全的手术。
