中文摘要:目的:探讨经食管超声心动图(TEE)在经胸小切口室间隔缺损(VSD)封堵术中的应用价值。方法:术前经胸超声心动图(TTE)初步筛选适合封堵的VSD患者150例,术前TEE明确VSD位置、大小,选择合适的封堵器,然后在TEE引导下完成整个封堵过程, 并在术后即刻评价封堵效果, 确认是否有残余分流或并发症。术后3~4 d复查TTE。结果:147例患者封堵成功;3例患者未成功,行体外循环下VSD修补术。术后3~4 d随访TTE,无室水平残余分流,无新出现的主动脉瓣、三尖瓣及肺动脉瓣反流,原有的瓣膜反流未加重。结论:在经胸小切口VSD封堵术中TEE在选择合适患者、选择封堵器大小、指导封堵器的释放以及疗效评价方面均具有重要的作用。
英文摘要:Objective: To study the value of echocardiography in closure of ventricular septal defects (VSD) during the minimally invasive cardiac surgery.Methods: One hundred and fifty patients with ventricular septal defect (VSD) were examined by transthoracic echocardiography (TTE). TTE usually allowed to select patients to be suitable for closure in this operation. During the operation TEE evaluated the exact size, position of the defect and inspected the occluder releasing. TEE observed whether the presence of residual shunt or not. Results: One hundred and forty-seven patients were closed successfully. After 3 or 4 days following, no residual shunt was found. Conclusions: TEE plays an important role in case selection, guidance of occluder device release and evaluating operation effect.
