Repair of recurrent coarctation using an ascending aortic autograft

Results of aortic arch repair for interrupted aortic arch or aortic coarctation have considerably improved. However, re-stenosis or aneurysm formation is a common complication requiring complex re-interventions or even extra-anatomic bypass grafting. In two patients with recurrent coarctation, the use of cardiopulmonary bypass was mandatory, in one due to the concomitant repair of the intra-cardiac defect, in the other due to the small aortic arch, the long segment aortic coarctation and the small diameter of the supra-aortic vessels. In both patients a segment of the ascending aorta was interposed between the distal aortic arch and the proximal descending aorta with uneventful postoperative courses and freedom from pathological findings at 1 year and 6 months follow-up. In patients undergoing complex congenital heart surgery involving the ascending aorta, a segment of the autologous ascending aorta may be used to repair recurrent isthmic stenosis, avoiding the use of any foreign material.
