An unusual case of concordant ventriculoarterial connections, subpulmonary infundibulum, and parallel arterial trunks: a diagnostic challenge

We present an unusual case of concordant ventriculoarterial connections, subpulmonary infundibulum, and parallel arterial trunks. This case was complicated by extreme pulmonary artery tortuosity and low arching aorta causing severe tracheal compression. We discuss the difficulty in prenatal diagnosis, necessity for advanced imaging postnatally, and associated airway complications.
