    Abstract:
    Background: Coarctation of the aorta can be associated with significant hypoplasia of the aortic arch. In contrast to patch aortoplasty, ascending sliding arch aortoplasty uses viable autologous tissue for potential growth in children. We reviewed the mid- to long-term outcomes of this technique. Methods: Between 2002 and 2023, 28 patients underwent ascending sliding arch aortoplasty for the patients with coarctation of the aorta (n = 22) and interrupted aortic arch (n = 2). Four patients underwent previous surgical coarctation repair at other institutions. The median patient age and body weight were 28.5 months (3 weeks to 15.6 years) and 13.4 kg (3.7-70 kg), respectively. Results: Although one patient had a recurrent nerve injury postoperatively, there were no other major morbidities or mortalities. The last follow-up echocardiography demonstrated that the mean peak velocity improved from 3.9 ± 0.6 to 0.9 ± 0.8 m/s, and the pressure gradient improved from 63.6 ± 21.5 to 7.1 ± 7.7 mm Hg. The postoperative diameters of the ascending aorta, proximal arch, distal arch, and isthmus all increased significantly. The mean postoperative length of stay was 5.9 ± 2.1 days, and the median follow-up time was 7.3 years (10 days to 20.5 years). No reoperation or catheterization-based intervention was performed for residual coarctation. Conclusions: Ascending sliding arch aortoplasty is safe and effective for treating coarctation of the aorta with aortic arch hypoplasia. This technique is applicable for children ranging in size from neonates to older children (or adolescents), recurrent coarctation cases, and provides complete relief of narrowing by utilizing viable native aortic tissue.
