Staged treatment of a premature newborn with interrupted aortic arch and aorta-pulmonary window using intraoperative hybrid procedure before subsequent total correction - Long-term follow-up.

Interrupted aortic arch (IAA) associated with an aortopulmonary window (APW) is a rare cardiac malformation that needs an immediate diagnosis after birth and surgical treatment to avoid irreversible pulmonary lesions. Herein, we describe a case of successful staged treatment of premature neonate using many operative procedures. The first stage was stenting of patent ductus arteriosus with banding of pulmonary artery branches using a hybrid approach. At the age of one, he underwent total correction of malformation using Gore-Tex patch. Two procedures of implantation and redilatation of the previously implanted stents were performed in the following years. In the 8-year follow-up, the patient has been in good clinical condition, without cardiac symptoms. To the best of our knowledge, this is the first case report representing such a long-term follow-up of treatment of IAA accompanied by APW.
