    Abstract:
    OBJECTIVES: The aim of our prospective randomized study was to compare modified reverse aortoplasty (MRA) and extended end-to-end anastomosis (EEA). METHODS: We have assessed the operative correction results in 54 infants with coarctation of the aorta and distal aortic arch hypoplasia who underwent primary repair in our institute between July 2013 and February 2014. All of the patients were <12 months old when they had the operation. Patients were randomly assigned to 2 arms: modified reverse subclavian flap angioplasty (MRA group; n = 27) or extended end-to-end anastomosis (EEA group; n = 27). RESULTS: We found a significant difference in residual arterial hypertension between the groups: 2 (7.7%) patients in the MRA group and 8 (30.8%) patients in the EEA group, respectively (P = 0.03). Risk factors for arterial hypertension were precoarctation area rigidity and endocardial fibroelastosis. During the last follow-up visit, recoarctation was observed in 1 (3.8%) patient in the MRA group and in 2 (7.7%) patients in the EEA group, respectively (P = 0.50). Cox regression analysis showed that the only risk factor for recoarctation was the patient's low weight before surgery [odds ratio (95% confidence interval) 0.016 (0.001-0.51), P = 0.047]. An aortic aneurysm developed in 2 (7.7%) patients in the MRA group; however, no significant difference was found between the groups (P = 0.15). CONCLUSIONS: The results of surgical repair of coarctation of the aorta using modified reverse subclavian flap angioplasty and extended anastomosis were comparable in mortality rates and early postoperative complications. Nevertheless, MRA may be beneficial in reducing residual arterial hypertension at the mid-term follow-up visit.
