This study aimed to evaluate whether recoarctation of the aorta (reCoA) after the Norwood procedure for hypoplastic left heart syndrome correlates with pre- and postoperative anatomic factors. METHODS This retrospective study included 48 patients who underwent Norwood procedure with right ventricle-to-pulmonary artery conduit between 2009 and 2017. Anatomical factors such as preoperative length, diameter of the main pulmonary artery (MPA), and postoperative neoaortic arch angle stratified by arch reconstruction technique were analysed using the receiver operating characteristic analysis. RESULTS Eleven patients needed surgical intervention for reCoA at stage 2. Out of the 30 patients who underwent direct anastomosis during arch reconstruction, 7 developed reCoA. Seven patients received the full patch augmentation (patch augmentation for both lesser and greater curvatures) and were all spared from reCoA. Among the patients who had direct anastomosis, the preoperative MPA length was correlated with the postoperative arch angle (P = 0.021) and was associated with the occurrence of reCoA (P = 0.002) and the best cutoff value for MPA length was 10 mm. The postoperative arch angle was also correlated with the incidence of reCoA (P < 0.001) and was larger in patients who underwent the full patch augmentation than in patients who had direct anastomosis (126° vs 112°, P = 0.005) despite comparable MPA length. CONCLUSIONS ReCoA after the Norwood procedure correlates with MPA length when a direct anastomosis was used. Direct anastomosis can be considered in patients with a longer preoperative MPA. In other cases, the full patch augmentation should be considered for obtaining a large and smooth neoaortic arch. |
