Abstract

OBJECTIVE:

We retrospectively reviewed the result of patients who underwent transcatheter closure of ventricular septal defect (VSD) using Amplatzer® Perimembranous or Amplatzer® muscular VSD device (the Amplatzer® group) and Nit Occlud® Lê VSD Coil (the Pfm group).

BACKGROUND:

Perimembranous type (PmVSD) and doubly committed subarterial (DCSA) VSD were the major isolated congenital heart defects in Thai children. Transcatheter device closure technique for both types of VSD has emerged as an alternative treatment to surgery.

METHODS:

Retrospectively, data was reviewed between 2003 and 2009.

RESULTS:

116 patients were enrolled. Device or coil was successfully implanted in 94%. Complete closure at 24 hr is slightly higher in the Amplatzer® group. The average size of VSD in the Amplatzer® group was larger than the Pfm group (P = 0.001). The Pfm coil was primarily deployed in DCSA VSD when compared with the Amplatzer® group (P < 0.01). At 6 months follow-up the residual shunt was comparable (P = 0.054). There was only one transient AV block (AVB) in the Pfm group and 5 AVB in the Amplatzer® group. Four pacemakers were placed in the Amplatzer® group.

CONCLUSIONS:

Transcatheter closure of VSD in both Pm VSD and DCSA can be achieved by using either of the device. The Amplatzer® VSD device had the advantage of closure of larger defects with immediate less residual shunt but appeared to have a significant number of 3° AVB, which required pacemaker implantation. The Nit Occlud® Lê VSD Coil had the advantage of closure of both types of defects, in particular DCSA VSD with only small residual shunt.
