实时三维经食管超声心动图在二尖瓣成形术中的应用价值

目的 初步探讨实时三维经食管超声心动图在二尖瓣成形术中的临床应用价值.方法 采用Philips IE33 超声诊断仪、X7-2t探头.应用实时三维经食管超声心动图对6例二尖瓣脱垂患者二尖瓣成形术前、术后进行评价,并与心外科手术结果对照.结果 实时三维经食管超声心动图能准确评价和真实显示二尖瓣脱垂的形态、部位、范围、空间关系及并发症,与心外科视野和手术结果一致,在二尖瓣成形术前的决策中起重要作用.结论 实时三维经食管超声心动图为二尖瓣成形术提供了快速而准确的评价手段.

The role of real-time three-dimensional transesophageal echocardiography in mitral valve repair

Objective To investigate the value of real-time three-dimensional transesophageal echocardiography(RT-3DTEE) in mitral valve repair. Methods RT-3DTEE was performed in six patients[5 male,1 female,mean age (45.7±12.6)years] with mitral valve prolapse by using Philips IE33 with X7-2t probe.Preoperative RT-3DTEE studies were compared with surgical findings in patients undergoing surgical repair. Results RT-3DTEE could display dynamic morphology of mitral valve,the location of prolapse,and spatial relation tO the surrounding tissues.It could provide surgical views of the valves and the valvular apparatus.RT-3DTEE results were consistant with surgical findings.Conclusions RT-3DTEE is a unique new modality for rapid and accurate evaluation of mitral prolapse and mittal repair.
