Abstract

We report a 7-year-old boy with tetralogy of Fallot who developed a right ventricular pseudoaneurysm one year after right ventricular outflow tract reconstruction with a 17 mm pulmonary homograft. Urgent reoperation revealed proximal homograft dehiscence. Repair was performed using an Invengenx® pericardial patch. This rare complication highlights the importance of long-term surveillance following homograft implantation in congenital heart surgery.
