Transcatheter closure of congenital ventricular septal defects using the Amplatzer Duct Occluder II device: preliminary data from a Tunisian monocentric study.

INTRODUCTION

Percutaneous closure of congenital ventricular septal defects (VSDs) represents a promising alternative to surgery with lower rate of complications and shorter hospital stay. Its main limitation is the choice of the appropriate device for each type of defect.

AIM: To report the experience of the service of cardiology (Sahloul hospital, Sousse, Tunisia) in percutaneous closure of congenital VSDs with Amplatzer Duct Occluder II (ADOII).

METHODS

This was a retrospective, monocentric study, conducted from January 2013 to December 2017. The study included patients treated by percutaneous closure of congenital VSDs with the ADOII device.

RESULTS

Twelve patients (6 boys; 6 girls) were included. The mean±SD of patients' age and weight were 65±41 months and 23±10 kg, respectively. VSDs were peri-membranous (n=9) and muscular (n=3), and defects were restrictive (n=11) and non-restrictive (n=1). The mean (minimum-maximum) size of VSDs was 4.72 (3-6) mm. Eleven ADOII prostheses were successfully implanted. One failure procedure was noted with migration of the device into the pulmonary artery. A second child with perimembranous defect developed transient atrioventricular block. No deaths occurred.

CONCLUSION

The present early experience shows that percutaneous closure with ADOII device of perimembranous and trabecular VSDs is safe and effective.
