Abstract:
Objective To evaluate the clinical safety and efficacy of percutaneous interventional therapy in pediatric patients with secundum atrial septal defect(ASD).Methods Clinical data of 40 patients(age≤2 years)with secundum atrial septal defect treated in our hospital from February 2014 to December 2017 were analyzed retrospectively. There were 13 males and 27 females in these patients.Ultrasound of heart showed that there were 37 patients with single ASD,3 patients with multiple ASDs.One associated with pulmonary stenosis(PS),and 1 associated with patent ductus arteriosus.There were 6 patients with pulmonary hypertension, and the diameter of ASD was (10.6 ± 2.0) mm. All patients were proved to have secundum atrial septal defect before intervention.In the intervention,the transport system was delivered along the femoral vein,inferior vena cava and right atrium through atrial septal defect to the left atrium,and the occluder was released there. Results Of the 40 patients, 38 cases were successfully implanted, and the other two patients were not satisfied with the location of occlusion.The diameter of the ASD occluder was(12.0±2.1)mm and the transport sheath 7-9 F.Plug2 occluder was implanted in the patient with patent ductus arteriosus.To the patient with PS,pulmonary valve balloon angioplasty was performed,and then the pressure gradient reduced obviously, after that ASD occlusion was performed. The total follow up period was from 2 months to 3 years.No residual shunt and unsatisfactory device position were found during the follow up period.The pulmonary pressure reduced to normal,and the right atrium and right ventricle were smaller in a different degree. All patients had no arrhythmia and other complications.Conclusion Transcatheter closure of ASD is safe,reliable,and has fewer complications.It is worthy of popularization and application.Appropriate occluder should be selected according to the size and edge of ASD to reduce complications,such as residual shunt and valve injury.
