Myocardial Work in Aortic Regurgitation: It  Also Works!
The management of chronic severe aortic regurgitation (AR), specifically the timing of intervention, remains challenging. The interplay between increasing left ventricular (LV) dilation and eccentric LV hypertrophy maintains stroke volume, resulting in both an increased preload and an increased afterload state. These mechanisms account for the “long latent phase” of chronic severe AR. Only once these mechanisms of LV compensation are exhausted does LV ejection fraction (LVEF) begin to decline. The 2020 American College of Cardiology/American Heart Association valve guidelines are similar to European guidelines and reco...
