Ascending aortic slide for interrupted aortic arch repair: a new approach to maintain native tissue continuity

Interrupted aortic arch (IAA) is characterized by the absence of luminal continuity between segments of the aortic arch and the proximal descending aorta (1,2). It is a rare congenital malformation that is often associated with a ventricular septal defect (VSD), and may coexist with severe intracardiac congenital anomalies such as common arterial trunk (CAT), transposition of the great arteries (TGA), aortopulmonary window (APW) or hearts with single ventricle connection (1-3).
