[Echocardiographic and color Doppler diagnosis in congenital aneurysm of the mitral-aortic intervalvular fibrous tissue].

We describe the case of a 12-years-old boy, who had an echocardiogram for sports fitness. The echocardiographic image showed a small probably congenital aneurysm of the mitral-aortic intervalvular fibrosa. The diagnosis of this rare anomaly was made possible by the combination of bidimensional echocardiographic and Color Doppler information.
