A case of subannular aortic aneurysm detected by transoesophageal echocardiography.

Subvalvular aortic aneurysm is a cardiac abnormality extremely uncommon in white adult patients. Accurate diagnosis can be made by transoesophageal echocardiography which is the modality of choice for non-invasive recognition of aortic and subaortic abnormalities. In this report we describe, in a 47-year-old white man with subvalvular aortic aneurysm associated to aortic bicuspid valve, the echocardiographic diagnosis and cardiac intervention of aortic valve replacement with surgical obliteration of the orifice. A good surgical result was confirmed by an echocardiographic transthoracic examination performed after 6 months.
