Five Years Follow-Up in Children with Secundum Artrial Septal Defect Using Amplatzer Occluder Device / 实用儿科临床杂志

ABSTRACT

Objective To evaluate the efficiency of transcatheter closure of secundum artrial septal defect (ASD) using Amplatzer occluder device in 5 years.Methods There were 18 children with ASD.Each ASD was occluded using Amplatzer occluder device through the percutaneous procedure.The closure procedure was guided by fluoroscopy and transthoracic echocardiography.All patients were followed up by physical examination,color flow echocardiography,chest radition,electrocardiography at 48 h,1month,3 month,6 month,one year,two years,three years,four years and five years.Results Cardiac murmur disappeared or lightened.Arrhythmia and right heart volume in all patients were improved after the procedure.A case revealed a trival shunt of short duration and vanished after one month color flow echo.A case has “spring′s beat” in heart when she goes to bed in three years after the procedure.Another patient had serious headach after closure and recoved after heparin therapy.Conclusions Transcatheter closure of secundum ASD using amplatzer occluder device is safe and efficient by follow-up.In order to prevent cerebral embolism,heparin should be injected in vein in two days.
