title: How to relate diastolic left ventricular dysfunction to the results of stress echocardiography in aortic stenosis?
abstract: In aortic stenosis (AS), altered functional capacity may be not only a result of impaired systolic performance but likewise of diastolic left ventricular (LV) dysfunction. In asymptomatic severe AS, in borderline severe AS and in low flow, low gradient AS with reduced ejection fraction (EF), assessment of systolic and diastolic LV function should be completed by evaluation of functional capacity using low dose dobutamine stress echocardiography (SE).
