Abstract
Ventricular septal defects (VSDs) are a prevalent congenital heart anomaly demanding safe and lasting interventions. This paper explores the application of Invengenx® bovine pericardial patch (Tisgenx, Irvine, California), a promising biomaterial, in VSD repair. We present two case studies: a seven-month-old infant and a three-year-old child undergoing VSD closure using autologous and bovine pericardial patches, respectively. Both patients tolerated the procedures well, experiencing no intra-operative complications and demonstrating excellent postoperative recovery. Echocardiography postoperatively showed no complications and improved clinical outcomes. Notably, the pericardial patches exhibited excellent integration and suture retention, highlighting their durability and compatibility with the growing heart. These cases establish the feasibility and effectiveness of the Invengenx® pericardial patch for VSD repair. The favorable outcomes in terms of safety and efficacy support the potential of this biomaterial as a valuable alternative in pediatric cardiac surgery, particularly for complex VSDs or patients with contraindications to synthetic patches. Further research is crucial to unlock the full potential of bovine pericardium as a durable and advantageous option for VSD repair in a broader range of pediatric patients.
