[Stress echocardiography with dobutamine in patients with aortic stenosis].
Echocardiographic examination at rest is usually an adequate diagnostic method in evaluating patients with aortic stenosis and in assessing the severity of stenosis. However, in patients with aortic stenosis with coexisting coronary heart disease and in patients with poor left ventricular systolic function and low gradient aortic stenosis, dobutamine stress echocardiography should be performed. This test is helpful in differentiating between significant fixed aortic stenosis with secondary left ventricular dysfunction and severe left ventricular dysfunction coexisting with nonsignificant aortic valve stenosis. This examination is necessary to select the proper method of treatment and is helpful in risk stratification.
