Aortico-left ventricular tunnel (ALVT) is a rare congenital malformation characterized by an abnormal communication between aorta and left ventricular cavity and the child presents with features of congestive heart failure in early infancy. We report the case of a 7-day-old baby who was diagnosed as a case of ALVT by echocardiography. The child was operated successfully and echocardiographic findings were confirmed.
