In some patients, the severity of aortic valve stenosis is difficult to estimate. In an elderly patient with aortic valve stenosis, heart failure and other co-morbid conditions, severity of aortic valve stenosis was estimated with a dobutamine stress echocardiography. The patient died six days after valve replacement. A literature search revealed pitfalls in the diagnostic procedure and difficulties in the interpretation of dobutamine stress echocardiography. Absence of contractile reserve, low mean transvalvular gradient and presence of coronary artery disease in this patient can be considered as increased risk. However, valve replacement might be offered on an individual basis.
