An 8-months-old boy, presenting with heart failure and murmur was investigated using echocardiogram and cardiac catheterization revealing a fistula (aortic-leaft ventricular tunnel) between the aorta and the left ventricle, bypassing the aortic valve and thereby causing massive regurgitation through this tunnel as was demonstrated by Doppler ultrasonography. The patient was submitted to surgery to occlude the tunnel through the aortic orifice under cardiopulmonary bypass. A postoperative echocardiogram revealed complete occlusion of the tunnel and the patient is completely free of symptoms.
