Abstract:
Objective To evaluate the safety and efficacy of transcatheter closure of perimembranous ventricular septal defects(VSD) using domestic symmetric double-disk occluders.Methods From March 2003 to July 2007,689 VSD patients were treated with transcatheter intervention using domestic symmetric double-disk occluders and received clinical follow up at 1 month,3 months,6months after the procedure and annually thereafter.Complications including residual shunt,heart rhythm changing,shape of the occluder and the presence of tricuspid/aortic regurgitation were observed thoroughly.Results The overall technical success rate was 98.8%.One patient died of cerebral bleeding 7 days after intervention.One patient suffered complete A-V block and required permanent pacemaker implantation and another patient conversed to open surgery because of moderate tricuspid regurgitation.Asymmetric Amplatzer occluders were used in 6 patients but the intervention failed in 2 patients whom required an open conversion.Comorbidities such as atrial septum defect,patent foramen ovale were treated concomitantly.No other complications were observed during the follow-up period.Conclusion Complication associated with transcatheter closure of perimembranous VSD using domestic symmetric double-disk occluders was relatively low.The procedure was safe and applicable.Meanwhile,it is necessary to stick to the procedural indications and avoid complications such as tricuspid regurgitation etc.
