Abstract

Background: Ventricular septal defect (VSD) is a common congenital heart defect. The double-disk occluder method has been developed to enhance treatment efficacy and minimize complications compared to traditional devices. Objective: To describe the procedure for perimembranous VSD closure using a double-disk occluder. Methodology: A prospective descriptive study was conducted at Hanoi Heart Hospital on 81 patients diagnosed with perimembranous VSD. Clinical, paraclinical, and interventional data were collected. Key indicators included pulmonary artery systolic pressure, left-to-right shunt ratio (Qp/Qs), device size, procedural time, and complications encountered during treatment. Data analysis was performed using SPSS 20.0. Results: Common clinical symptoms included recurrent bronchitis (33.3%) and poor weight gain (25.9%), with systolic murmurs ≥ 3/6 detected in 80.2% of patients. The mean pulmonary artery pressure was 27.4 mmHg, and the mean Qp/Qs was 2.3. The most frequently used occluder sizes were 5 mm (30.9%) and 6 mm (27.2%). The average procedure time was 47.3 minutes, with a high success rate. Challenges such as device dislodgement, snare recapture, or upsizing the device were successfully managed. Conclusion: This method demonstrates safety, efficacy, and broad applicability in clinical practice while providing additional evidence of the role of the device in the treatment of congenital heart defects.
