The management of asymptomatic patients with severe aortic stenosis is challenging. Unfortunately, evaluation of symptoms such as dyspnoea remains subjective. The use of exercise echocardiography may help to predict major events in patients with asymptomatic severe aortic stenosis. This article explains how to perform the test and discusses which echocardiographic measurements should be obtained, focusing on the diagnostic and prognostic value of these measurements. An increase in mean transaortic pressure gradient >or= 18 mmHg predicts a worse prognosis in patients with severe aortic stenosis. The absence of left ventricular contractile reserve also has an important prognostic impact. Evaluation of filling pressures and looking for a worsening or a new mitral regurgitation are also part of the exam. Further studies are required to determine whether surgery should be recommended in the presence of an abnormal exercise echocardiogram in severe asymptomatic aortic stenosis.
