Catheter closure of ventricular septal defects using Amplatzer occluder / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinic effectiveness and safety of transcatheter closure of ventricular septal defect using homemade Amplatzer VSD occluder. Methods From Jan 2003 to April 2005,16 patients (11 males,5 femles) with VSD underwent an attempt of catheter closure using homemade Amplatzer occluder.The mean age of patients was (13.98 ?11.05) years (ranged from 3.5 to 41 years);the mean weight of patients was (32. 1 ?17.59) kg (ranged from 12.5 to 59 kg);the mean diameter ofVSD measured by transthoracic echocardiography (TTE) was(5.34?1.75)mm(ranged from 3.7 to 9mm). All patients underwent closure under TTE or transthoracic echocardiography(TEE)guidance. Results The devices were deployed successfully in 12patients.There was complete closure in 11patients immediatelly,and residual sbunt in 1 patients.After proccdure, bundle branch block(right and left bundle) were occurred in 7patients.Hemolysis was in 1patients.There were no other servere complications.Conclusions Transcatheter closure of VSD using this new occluder is safe and effective. Early results are good.Further clinical trials are underway to assess the long-term results.
