Abstract

Background: Ventricular septal defect is the most frequent congenital heart disease, with the peri-membranous ventricular septal defect (Pm-VSD) being the most frequent subtype. 
Aim: To assess the success rate and complications of device closure of symptomatic, hemodynamically significant Pm-VSDs using single-disc and double-disc devices.
Patients and methods: This investigation was a cross-sectional comparative investigation performed on twenty cases with pm VSD at Cardiology Department, Faculty of Medicine, Al-Azhar University at the duration from June 2023 to January 2024.
Results: There was no significant distinction in ventricular septal defect size or angiography before closure between single and double disc cases, with a p-value more than 0.05. Nevertheless, there was a significant distinction in looping, fluoroscopy time, and technique. In the single disc group, all cases (100%) underwent an antegrade technique. There was a significant difference in RS, with a higher number of cases in the double disc group (10 cases 90%) than the single disc group, p-value less than 0.05. No immediate complications occurred in both groups. All cases presented with sinus rhythm before closure, no case developed complete heart block, only one patient developed RBBB post procedure in the double disc group.
Conclusion: Trans-catheter closure of ventricular septal defects is safe and efficient in selected cases. Both single- and double-disc devices are equally effective and safe.
