[Aorto-left ventricular tunnel arising from the left sinus of Valsalva]

Aortic-left ventricular tunnel (ALVT) is a rare congenital anomaly in which an abnormal communication connects the ascending aorta with the left ventricle, bypassing the aortic valve. Usually the ALVT takes its origin from the right aortic sinus. We report a patient with an ALVT arising from the left sinus of Valsalva who underwent surgery at five months of age. The diagnosis was first established by two-dimensional echocardiography.
