Regardless of etiology, aortic valve insufficiency results in volume overload on the LV because the LV is forced to pump the entire diastolic volume received from the left atrium and the regurgitant volume from the aorta through an incompetent aortic valve. (medscape.com)
When LV function cannot continue to compensate for volume overload, the LV dilates, and LV end-diastolic volume increases, even without further increase in aortic regurgitation volume. (medscape.com)
