Objective: To evaluate the short-term outcomes of percutaneous closure of ventricular septal defects in patients of all age. Summary: Ventricular septal defect (VSD) is the most common congenital heart defect and can be detected during the prenatal and postnatal period. In 1987, Lock et al first applied the technique of interventional occlusion of the VSD using devices through a catheter and this method quickly spread worldwide. Compared with surgery to repair VSD, intervention to occlude the ventricular septum with devices through a catheter helps minimize complications after the procedure, reduces hospital stay time and costs, avoids surgical scars, has less psychological impact. and patient quality of life. Since 2014, the Cardiovascular center – E hospital has also conducted the first VSD occlusion interventions. After 10 years of performing this technique, this is the first study conducted on subjects who underwent intervention using percutaneous devices at the Cardiovascular center – E hospital with a large number of patients including successful, failed, and complicated cases to evaluate the success rate and outcomes after intervention. Subjects and methods: Retrospective, descriptive study. From October 2014 to October 2023, 427 patients diagnosed with ventricular septal defect underwent percutaneous closure of ventricular septal defect. Results: Mean age was 7.37 years old, mean weight was 19.08 kg, In echocardiography, the main ventricular septal defect was membraneous, accounting for 96.3% of all cases. The success rate was 94.6%, with a male/female ratio of 206/221. There were a total of 22 cases of complications, of which 2 cases required surgical intervention to manage the complications. No patient died or developed complete atrioventricular block. Conclusion: Percutaneous ventricular septal defect closure procedure is a high success rate, and should be widely implemented to minimize surgical risks for patients.
