实时三维经食管超声心动图的临床应用研究

目的 探讨实时三维经食管超声心动图临床应用的可行性及价值.方法 应用实时三维经食管超声心动图对59例不同类型心脏病患者进行检查或术中监测,其中心律失常20例,瓣膜病变24例,先天性心脏病12例,主动脉夹层2例,不明原因肺动脉高压1例.结果 所有患者均成功完成实时三维经食管超声心动图检查或术中监测,能清晰显示正常心内结构及病变的三维图像,成像质量好,分辨力高.结论 实时三维经食管超声心动图安全可靠,可用于经胸声窗不佳者及术中监测,补充经胸实时三维超声的不足,在术中应用时不干扰手术野及手术进程,具有良好的临床应用价值.

Clinical application of real time three dimensional transesophageal echocardiography

Objective To investigate the feasibility and clinical application of real-time threedimensional transesophageal echocardiography(RT3D-TEE). Methods Fifty-nine patients with various heart diseases were examined or monitored by RT3D-TEE.Among them,20 patients with different kinds of arrhythmias,24 patients with valvular heart diseases, 12 patients with congenital heart diseases,2 patients with aortic dissection, 1 with unexplained pulmonary hypertension. Results RT3D-TEE was performed successfully in all the patients with good image quality and the normal tissues as well as diseased cardiac structures were distinctly displayed.Conclusions RT3D-TEE is a safe and reliable new technique which can be applied in the patients with poor acoustic window and may be a powerful tool in the intraoperative monitoring.RT3D-TEE is also an important supplement to real time three dimensional transthoracic echocardiography and makes it possible for the first time to monitor the cardiac operation with RT3D-TEE without interrupting the operation procedure.
