Background: Coarctation of the aorta is a congenital malformation that has long been considered completely correctable with appropriate surgery in childhood. However, with the aging of these patients, many late complications have been reported, and this notion must be reevaluated.
Methods: We retrospectively reviewed all patients who underwent reoperation between 1992 and 2012 in our adult cardiac surgery department following surgical correction of coarctation in childhood; 18 patients over 15-years old were included in the study.
Results: The median time from coarctation repair to reoperation was 25 years. Patients were reoperated on for several late complications: aortic valve disease secondary to bicuspid aortic valve, ascending aortic aneurysm, recoarctation, aortic arch hypoplasia, pseudoaneurysm, associated recoarctation and pseudoaneurysm, subvalvular aortic obstruction, and descending thoracic aortic aneurysm. One patient died due to an intraoperative complication. In the other cases, the surgical results were satisfactory at the 6-month follow-up. According to literature data, age at coarctation repair and surgical technique appear to be essential factors in late complications: older age and surgical repair with prosthesis interposition are associated with a higher rate of reintervention.
Conclusion: Patients who have undergone repair of aortic coarctation frequently remain asymptomatic for a long time. Late complications can be appropriately treated when diagnosed early. Consequently, all coarctation patients need careful lifelong follow-up, especially those with congenital aortic valve disease or surgery in childhood with interposition of prosthetic material.
