Does exercise echocardiography predict the development of left ventricular dysfunction in patients with asymptomatic severe aortic regurgitation?
Contractile reserve assessed by exercise echocardiography is a strong predictor of left ventricular decompensation in asymptomatic patients with severe aortic regurgitation, which may help optimize the timing of surgery.
