A case is presented of a 3.5-year-old boy with aorto-left ventricular tunnel. A diagnosis of isolated aortic regurgitation had been made at the age of 11 months following cardiac catheterization with selective left ventricular angiography and aortography. The correct diagnosis was established 2.5 years later following cross-sectional echocardiographic examination combined with color Doppler investigation.
