title: [Aortic stenosis: interest in echocardiography with dobutamine].
abstract: The stress echocardiography with dobutamine confirms her increasing value for the patients with severe aortic stenosis and left ventricular dysfunction in a diagnosis concept by selecting the true severe stenoses and revealing stenoses overestimated by the low fow, and especially prognosis by means of the stratification of the operatory risk and the search for a contractile reserve which represent the guarantee of a survival per and postoperatoire satisfactory. As regards asymptomatic aortic stenosis the times of intervention are in reevaluation, the compliance valvulaire represent reliable means which needs confirmation for a prophylactic indication for surgery.
