Aortico-left ventricular tunnel is a rare congenital cardiac defect that bypasses the aortic valve via a para-valvular connection from the left ventricle to aorta. In most cases, the tunnel arises from the right aortic sinus. In this case report, we present a case of Aortico-left ventricular tunnel, in which the aortic orifice arose from the left aortic sinus, requiring special attention to avoid injuring the left coronary artery at the time of surgical repair.
