摘要
目的 :探讨用自制双盘状室间隔缺损 (室缺 )封堵器经导管闭合膜部室缺的可行性和临床疗效。方法 :6例先天性心脏病膜部室缺患者 ,男、女各 3例 ,年龄 6～ 2 2 (14 .0± 5 .6 )岁 ,均经体检、心脏超声和左心室造影确诊。用 7F输送鞘管从右心系统送入自制双盘状封堵器 ,封堵后 10 min重复左心室造影和经胸心脏超声波检查 ,观察封堵的即刻效果。术后连续心电监护 5 d。 结果 :左心室造影测量室缺直径 3～ 5 (3.6 7± 0 .82 ) m m,所用封堵器直径为 6～ 10 (7.5± 1.38) mm ,6例患者封堵均获成功。术后左心室造影、经胸心脏超声检查显示无残余分流 ,心电监护无心律失常发生。结论
Objective:To investigate the feasibility and efficacy of transcatheter closure of membranous ventricular septal defects(VSD) with self made nitinol occluder. Methods:Transcatheter closure was attempted in 6 patients [3 men and 3 women, aged 6 22 years, mean age (14.0±5.6) years] with membranous ventricular septal defect. All patients were diagnozed by physical examination, echocardiography and left ventriculography. A 7F delivery sheath was advanced across the membranous VSD through a wire from femoral vein to deploy the occluder. Left ventriculography and transthoracic echocardiography were repeated to assess closure outcome after 10 min. Continuous electrical cardiograph monitoring lasted for 5 d. Results:The ventriculographic diameters of the defects were from 3 to 5 mm [mean (3.67± 0.82) mm]. The occluders were successfully deployed in all patients. The diameters of devices were from 6 to 10 mm[mean (7.5± 1.38) mm]. No residual shunt was found by left ventriculography and transthoracic echocardiography after the procedure, and no arrhythmia occurred in all patients. Conclusion:Transcatheter closure of membranous ventricular septal defects with self made nitinol occluder is a safe and effective method.
