This case illustrates an exceptionally rare association between aortopulmonary window and criss-cross heart, underscoring the value of prenatal detection and detailed postnatal imaging to delineate complex anatomical relationships. Early surgical intervention was mandatory, and the need for extracorporeal membrane oxygenation highlights the high intrinsic risk of this anatomical combination. Reporting such cases expands the limited literature on rare congenital cardiac malformations and may inform future refinements in diagnostic evaluation and perioperative management.
NETO et al. (2026) studied this question.
