BACKGROUND: Neonatal and infant aortic arch reconstruction remains a high-risk cardiovascular procedure requiring effective cerebral and myocardial protection. Variability in perfusion strategies may influence early hemodynamic stability and postoperative recovery. This study aimed to evaluate the early and short-term cardiovascular outcomes of a standardized beating-heart aortic arch reconstruction strategy incorporating simultaneous antegrade selective cerebral and continuous coronary perfusion.
METHODS: In this retrospective single-center cohort study, 31 consecutive neonates and infants undergoing aortic arch reconstruction between November 2022 and December 2025 were analyzed. A standardized surgical protocol was applied, consisting of extensive ductal tissue resection, interdigitating posterior end-to-end anastomosis, anterior autologous pericardial patch augmentation, and moderate hypothermic antegrade selective cerebral perfusion combined with continuous coronary perfusion via innominate artery cannulation. Early postoperative outcomes and short-term echocardiographic follow-up results were assessed.
RESULTS: The cohort included 31 patients, 22.6% of whom had complex associated cardiac anomalies requiring concomitant procedures. Median cardiopulmonary bypass and aortic cross-clamp times were 119 and 64 min, respectively. There was no in-hospital mortality. Major complications were infrequent, and median intensive care unit stay was 5 days. During a median follow-up of 6.8 months, one patient (3.2%) developed recoarctation requiring reintervention. No late mortality was observed.
CONCLUSIONS: A fully standardized beating-heart aortic arch reconstruction strategy incorporating simultaneous cerebral and coronary perfusion demonstrated favorable early cardiovascular and short-term outcomes, even in anatomically complex cases. Preservation of continuous coronary perfusion may be associated with improved myocardial stability and early postoperative recovery; however, these findings should be interpreted as observational and hypothesis-generating given the absence of a control group. Larger multicenter studies with longer follow-up are warranted to confirm these findings.
