超声心动图在改良Fontan术后开窗封堵中的应用

摘要

目的 评价超声心动图在改良Fontan术后开窗封堵中的应用价值.方法 11例行改良Fontan术后患儿在我中心接受开窗心导管介入封堵手术,术中造影建立轨道后,应用超声心动图判断输送轨道是否进入心腔,引导释放封堵器.结果 11例患儿均成功封闭.超声心动图准确引导确定输送轨道的建立,术后检查提示无残余分流,封堵器塑形状态满意.结论 超声心动图对于改良Fontan术后开窗介入封堵轨道的建立和封堵器的成功释放具有非常重要的价值,是此类手术成功的重要保障.%Objective To evaluate the value of echocardiography in Transcatheter Intervention of Fenestration after Modified Fontan Procedure. Methods 11 cases after fenestrated modified Fontan procedure were recruited for iranscathcter intervention under guidance of echocardiography. Echocardiography was aimed at establishing the delivery pathway and determining the plasticity of the implanted occluders. Results All the 11 cases underwent successful transcatheter invention without residual shunt. The implanted occluder recoiled with normal plasticity after being released. Conclusions Echocardiography plays a key role in establishment of delivery pathway and definitive occluder releasing during transcatheter intervention of fenestrated modified Fontan procedure, and acts as important assurance of such procedures.
