Outcomes of aortopexy for patients with congenital heart disease

Aortopexy is a surgical procedure in which the aortic arch is fixed at other structures, thus widening the interaortic space. This study aimed to evaluate the outcome of aortopexy by means of chest computed tomography for patients with congenital heart disease. The study retrospectively reviewed the medical records of 16 patients with congenital heart disease who had undergone aortopexy by compressed airway. The severity of compressed bronchus before aortopexy, immediately after aortopexy (≤ 1 month), and after the patient had grown up were compared. To estimate the efficacy of the aortopexy, the interaortic distance index was calculated. Of the 16 patients, aortopexy was performed at the ascending aorta in 7, at the descending aorta in 7, and at the transverse arch in 2. The diameter ratio between the narrowest bronchus and the trachea was improved after aortopexy, as was the diameter ratio before aortopexy versus immediately after aortopexy (n = 9; p = 0.018) and the diameter ratio before aortopexy versus after the patient had grown up (n = 11; p = 0.006). Also, the interaortic distance index was increased after aortopexy, as was the diameter before aortopexy versus immediately after aortopexy (n = 9; p = 0.039) and the diameter before aortopexy versus after the patient had grown up (n = 11; p = 0.014). The study had one case of mortality due to sepsis. As shown by the results, aortopexy in patients with a compressed airway between arches is a useful surgical option. Such a compressed airway between arches should be considered for patients with an unusual clinical course before and after open heart surgery.
