Prognostic value of exercise left ventricular end-systolic volume index in patients with asymptomatic aortic regurgitation: an exercise echocardiography study

Surgical timing of chronic aortic regurgitation (AR) remains a matter of debate because of limited data. This study assessed the prognostic value of exercise echocardiography in asymptomatic AR. This prospective study included 60 consecutive asymptomatic patients with isolated moderate or severe AR (mean regurgitant volume 56.7 ± 11.8 ml) and preserved ejection fraction who underwent exercise echocardiography. The clinical outcomes were defined...
