Transcatheter therapy for congenital heart diseases using the Amplatzer occluder: A report of 30 cases / 中国微创外科杂志

ABSTRACT

Objective To evaluate the short-term effectiveness of Amplatzer device closure for congenital heart diseases.Methods Under X-ray fluoroscopy or/and transthoracic echocardiography(TTE),percutaneous puncture of the femoral artery or vein was conducted and the Amplatzer occluder was passed through the catheter.Effectiveness evaluation by transthoracic echocardiography,electrocardiography(ECG),and X-ray examination was applied at 24 hours,1 month,6 months,and every 1 year after the procedure.Results In 1 case of perimembranous ventricular septal defect(VSD),the detachment of the Amplatzer occluder to the arch of aorta was due to an inadequate small size.This patient was immediately operated with successful removal of the device through the femoral artery and later underwent a re-deployment of a larger-sized Amplatzer occluder closure successfully.The remaining 29 patients with atrial septal defect(ASD),patent ductus arteriosus(PDA),or perimembranous ventricular septal defect underwent a successful deployment of the Amplatzer occluder on one session without complications.The operation time was 20~90 min (38?16 min),the X-ray exposure time was 5~45 min(18?10 min),and the length of hospital stay was 3~7 days(4?2 days).Conclusions Amplatzer occluder transcatheter closure of congenital heart diseases has advantages of simplicity of deployment,good safety,and high success rate.This procedure is suitable for patients with secundum ASD,membranous VSD,and PDA.
