ABSTRACT
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.

Despite the operational experience in the percutaneous closure of Patent ductus arteriosus (PDA), complications can arise during the procedure. To overcome these complications the choice of the device must be adapted to each patient. AIM: To report the experience of the cardiology department in the transcatheter device closure of PDA and to determine the influencing factors of choice of the device. METHODS: Our study included patients with patent ductus arteriosus that are admitted for transcatheter closure, between September 2003 and June 2016. RESULT: One hundred and fifty-three patients were included in our study. Transcatheter closure was not done in 9 cases. The transcatheter closure was successful in 140 patients. The complications were observed in 11 patients that includes device embolization in 3 cases, aortic protrusion in four cases pulmonary protrusion in three cases and inguinal hematoma in one another. Three predictive factors of complications were: age < 2 years, tubular PDA type C and ratio duct diameter/weight > 0.95. A mild residual shunt was observed at the end of the procedure in 22.85 % of the patients. The risk of residual shunt was significantly increased when the age < 2 years, the large PDA, the presence of pulmonary hypertension and the tubular C PDA. CONCLUSION: The choice of the device depends essentially on age, the weight and the duct anatomy.

BACKGROUND: Most of congenital ventricular septal defects evolve towards spontaneous closure of different mechanisms depending on their location. AIM: To determine the prevalence and factors associated with spontaneous closure of congenital ventricular septal defects. METHODS: We conducted a retrospective study of 1000 patients diagnosed with congenital ventricular septal defects in our department from January 2000 to December 2017. RESULTS: After an average follow-up of 52.65 months (± 76.93 months), 183 (18.88%) of ventricular septal defects closed spontaneously. The average time for spontaneous closure was 45.78 months (76.34 months). 30.77% of trabecular ventricular septal defects (p<0.05) and 16.93% of perimembranous defects closed spontaneously (p=0.17). 28.5% of perimembranous defects associated with aneurysm formation versus 17.4% of those without associated aneurysm evolved to spontaneous closure (p<0.05). 65.6% of spontaneous closure occured during the first 3 years of life. In multivariate analysis, trabecular site [OR=2.85; CI (2.05-3.97)] and aneurysms of membranous septum [OR=1.9; CI (1.41-2.8)] were independent factors associated with spontaneous closure of defects. CONCLUSION: The highest VSD closure rate was observed during the first three years of life. Trabecular site and aneurysms tissue of membranous septum were found as independent factors associated with spontaneous closure.
