title: Aortico-left ventricular tunnel: the elusive diagnosis.
abstract: We present a case of an infant prenatally diagnosed with bilateral outflow-tract obstruction and severe aortic regurgitation who underwent cardiac transplantation at 45 days of life. Aortico-left ventricular tunnel was subsequently diagnosed on pathologic examination of the explant heart. Aortico-left ventricular tunnel is a rare congenital cardiac malformation and can remain undiagnosed if the clinician has a low level of suspicion. Aortico-left ventricular tunnel should be considered in any fetus or newborn with aortic regurgitation.
