Transcatheter closure of congenital ventricular septal defects using the Amplatzer Duct Occluder II device:
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.
