OBJECTIVES The feasibility of mini-invasive closure of perimembranous ventricular septal defects has been proven, but can cause surgical incision or sternum injury. A relevant but, to date, unanswered question is whether there exists a treatment without surgical trauma, radiation exposure and arterial complications. METHODS From May 2017 to January 2020, a total of 449 patients with perimembranous ventricular septal defect [mean age 5.0 ± 6.1 years (range 0.8–52.0 years)] were involved in this study and underwent 2 different echocardiography-guided operative procedures [percutaneous device closure (group A) or percardiac device closure (group B)] based on the patients’ or their parents’ choice. The clinical data were collected and a retrospective analysis was performed. RESULTS Fifty-five (96.5%) cases were successfully occluded in group A, and 2 (3.5%) patients were converted to percardiac device closure; 379 (96.7%) patients in group B underwent percardiac device closure, and 13 patients (3.3%) were turned to open-heart surgery after occlusion procedure failure. There were statistically significant differences (P &amp;lt; 0.05) between the 2 groups in operation time, postoperative hospitalization time and blood transfusion requirement. No acute complications or severe adverse events (death, valve injury, complete atrioventricular block and embolism) occurred either in the early period or during the follow-up. CONCLUSIONS Percutaneous device closure can achieve the same validity and safety as percardiac device closure for treating perimembranous ventricular septal defects with a more rapid recovery and less trauma.
