Abstract:
Objective To discuss the methods of selecting different shapes occluder and to evaluate the feasibility,safety and efficacy of them in transcatheter closures of congenital ventricular septal defect (VSD) in children.Methods Transcatheter closures were performed in 226 children with congenital VSD,age ranging from 2 to 14 years(mean 5.62 years) under the guidance of transthoracic echocardiography(TTE) and fluoroscopy.There were 14 patients with intracristal VSD,209 patients with perimembranous VSD and 3 patients with muscular VSD.Left ventriculography and transthoracic echocardiography were performed repeatedly after the procedure to assess the effect of occlusion.The echocardiography and electrocardiography were scheduled before discharge,1,6 and 12 months for the follow-up.Results The occluders were deployed successfully in 211 patients.The successful rate was 93.4%.Thin waist shape occluders,were deployed in 7 patients;equal side shape occluders,were deployed in 191 patients;eccentric shape occluders were deployed in 12 patients,and muscular defect occluders were deployed in 1 patient.There were no complications encountered during or after closure.Conclusions It is very important in transcatheter closure of congenital in children to select different shape occluder according to pathologic characteristics.In general,equal side shape occluder is suita-ble for a large number of defect and it is easy for deployment.In some conditions,the other shape occluder may be necessary.
