Ascending aortic pseudoaneurysm is a rare complication in heart transplantation. Surgery is the most conventional management, but, in some cases, it is high-risky. We report the case of a ten-year-old child with heart transplantation that developed ascending aortic pseudoaneurysm in the aortic anastomosis successfully treated with two covered stents through endovascular management. To our knowledge, this is the first report about endovascular therapy of an ascending aorta pseudoaneurysm after heart transplantation in a pediatric patient.
