[Moderate aortic incompetence due to traumatic rupture of a cusp]

The authors recall a case of moderate aortic incompetence caused by traumatic rupture of an aortic cusp occurring in a man of 36 years of age. Anatomical lesions of the aortic valve usually lead to severe incompetence for which surgical treatment is required. In this case, the lesion was well tolerated from the clinical and haemodynamic points of view, and surgery was not required; this tolerance has extended into the mid term. The authors emphasise the importance of echocardiography in the diagnosis of disturbance of an aortic valve, and also in following up the progress of the subsequent aortic incompetence.
