Open, Hybrid, and Endovascular Treatment for Aortic Coarctation and Postrepair Aneurysm in Adolescents and Adults

Background. Open, hybrid, and endovascular procedures are used for grown-up patients with aortic coarctation and complications after repair, an expanding population. We sought to characterize patients and procedures, assess early and late outcomes, and describe indications to guide treatment of these complex patients. Methods. Between May 1999 and January 2011, 110 patients underwent open (n = 40), hybrid (n = 11), or endovascular (n = 59) repair of coarctation (n = 43), recurrent aortic coarctation (n = 42), or postrepair aneurysm (n = 25). Mean age was 38 +/- 14 years. Sixty-eight had previous repairs (median 27 years earlier; range, 1 to 50). Twenty-two had prior cardiovascular operations other than coarctation and 50% had bicuspid valve. Fifty-nine concomitant procedures were performed in 45 patients (40%). Data were from the prospective database, chart review, and Social Security Death Index. Results. Technical success was achieved in 100%, with no hospital deaths, no strokes, and no paraplegia. Complications were uncommon and included respiratory failure (n = 2, 1.8%), and temporary renal failure (n = 2, 1.8%). Twenty-two patients required reinterventions, but half of those were planned. There was no difference in occurrence of unplanned reintervention between approaches (endovascular 12%, hybrid 18%, open 12.5%). Length of stay was 4.8 +/- 4.8 days. Transcoarct gradient fell from 37.6 +/- 18 mm Hg preoperatively to 7.0 +/- 6.9 mm Hg in coarctation patients. Postrepair aneurysm patients had no late ruptures, and maximum diameter shrunk from 5.9 +/- 1.3 cm preoperatively to 4.8 +/- 1.3 cm. Estimated survival at 1, 5, and 8 years was 95%, 95%, and 90%, respectively. Conclusions. Coarctation, recurrent coarctation, and postrepair aneurysm/pseudoaneurysm in adolescent and adult patients can be safely and effectively managed with open, hybrid, or endovascular techniques. Optimal results are achievable in this complex population of patients with a multimodality approach tailored to surgical indication and anatomy. All survivors of coarctation repair require lifelong surveillance. (Ann Thorac Surg 2012;94:751-8) (C) 2012 by The Society of Thoracic Surgeons
