This case report illustrates a ductal-dependent coarctation repair in a neonate whose long isthmus was believed to make conventional end-to-end repair problematic. The isthmus and left subclavian artery were isolated and augmented with a homograft while flow to the descending aorta was preserved through the ductus. After patch augmentation of the isthmus, ductal tissue was resected and an end-to-end anastomosis was performed using the length of the augmented isthmus. Angiography 18 months later showed excellent growth of the arch despite homograft tissue comprising the majority of the isthmus at the time of repair.
