目的探讨在经食管超声心动图（TEE）引导下经胸封堵室间隔缺损（VSD）的临床经验。 方法回顾性分析2013年7月至2014年7月高州市人民医院23例先天性心脏病患儿的临床资料，其中男9例、女14例，年龄4个月至1岁。胸骨下段小切口暴露右心室前壁，在TEE引导和实时监测下，穿刺右心室前壁，建立轨道，通过短输送装置直接将封堵器安放在VSD部位。 结果23例患者全都封堵成功，置入封堵器直径6～10 mm，术后5～11 d出院，随访3～24个月，无残余分流、主动脉瓣反流以及心律失常等并发症。 结论TEE引导下经胸微创封堵婴儿室间隔缺损是一种简单安全的治疗方法。
Objective To explore the feasibility of transcatheter closure of congenital heart disease (CHD) under the guidance of transthoracic echocardiography (TTE). Methods A total of 37 patients with CHD who received transcatheter closure under the guidance of transthoracic echocardiography from November 2013 through November 2015 in our hospital were recruited. There were 15 males and 22 females, aged 1 to 16 years. Among them 32 patients suffered atrial septal defect and 5 patients had patent ductus arteriosus. The transcatheter closure of CHD was performed under the guidance of TTE. The patients underwent echocardiography follow-up at one, three and six months after surgery. Results Closure devices were successfully implanted in 37 patients under TTE guidance. The procedure was simple and safe. During the follow-up, no severe complication such as valvular injury, pericardial effusion, residual shunt and peripheral vascular injury occurred. Conclusion Transcatheter closure of CHD under TTE guidance is a feasible method and worth further clinical application.
