OBJECTIVE: Synthetic patch materials, such as polytetrafluoroethylene and knitted polyester, are commonly used for the repair of complete atrioventricular septal defects using the double-patch technique. In our study, we investigated the impact of glutaraldehyde-treated autologous pericardial patch on postoperative atrioventricular valve function.

PATIENTS AND METHODS: In this retrospective study, patients who underwent repair of complete atrioventricular septal defects using the double-patch technique between January 1, 2018, and May 15, 2023, at our pediatric cardiac center were included in the study. Patients were divided into two groups based on the type of patch used for the repair of the ventricular component of the atrioventricular septal defect: autologous pericardial patch (group 1) and polytetrafluoroethylene patch (group 2). Postoperative data of the patients were retrospectively analyzed.

RESULTS: Thirty-four patients (57.6%) were female, and 25 (42.4%) were male, with a median age of 7 (5-18) months. The median body weight at the time of surgery was 5.5 (4.1-10) kilograms. Down syndrome was present in 45 (76.3%) patients. The autologous pericardium was used for ventricular septal defect closure in 44 (74.6%) patients (Group 1), while polytetrafluoroethylene was used in 15 (25.4%) patients (Group 2). Permanent cardiac pacemaker placement was required in 4 (6.8%) patients due to postoperative atrioventricular block. Hospital mortality was 11.9% (n=7). Among these cases, 4 (6.8%) patients died from low cardiac output syndrome, and 3 (5.1%) patients died from sepsis. Postoperative echocardiographic evaluation revealed insignificant residual ventricular septal defects in 17 (28.8%) patients. No significant differences were observed between the groups in terms of mortality and postoperative atrioventricular valve insufficiency. The median follow-up duration for discharged patients was 5 months (7 days to 3.9 years). Throughout the follow-up period, there were no reoperations due to valve insufficiency or left ventricular outflow tract obstruction.

CONCLUSIONS: Glutaraldehyde-treated autologous pericardium is a safe material that can be confidently used for the repair of the ventricular component of complete atrioventricular septal defects. This patch material does not adversely affect atrioventricular valve function and allows for the successful closure of ventricular septal defects.
