Double Patch Repair for Complete Atrioventricular Septal Defect Using the Invengenx® Patch

Le résumé fourni par la source

Complete congenital Atrio-Ventricular (AV) septal defect repair is a complex technique and can be performed as a single patch, modified single patch or a double patch technique. In addition, reconstructive surgeries make it more challenging as the native pericardium available for the repair is limited and of poor quality. Thus, the use of engineered bovine pericardium can help in the reconstruction of large AV canal defects. We used the Invengenx® patch for the repair of a complete AV canal defect and Pulmonary Artery (PA) plasty in a 20 month old female child with a previous PA banding. The patch had good flexibility, mechanical strength, suturability and there were no complications such as thrombosis or infection on follow up. Reconstructive surgery in congenital cardiac anomalies is fraught with challenges due to surgical complexities and the limited availability of native pericardium for performing the repair of large defects. We used the Invengenx® bovine pericardial tissue patch for the repair of a complete AVSD (post-pulmonary artery banding) and found the patch to be suitable for the re-do procedure and noted uniform thickness, good flexibility, mechanical strength, suture retention and no infection or thrombosis.
