Abstract

BACKGROUND: The decision-making role of exercise echocardiography in the surgical timing for aortic regurgitation remains a matter of debate because of limited data on its link with outcome. The aim of this study was to assess the role of echocardiographic measurements at rest and during exercise as predictors of valve surgery in asymptomatic aortic regurgitation. METHODS AND RESULTS: Comprehensive resting and exercise echocardiography was performed in 159 consecutive patients (50±15 years; 80% male) with isolated moderately severe to severe aortic regurgitation and preserved left ventricular (LV) function (LV ejection fraction >50%, LV end-diastolic dimension ≤70 mm, LV end-systolic dimensi..
