Answer

Manifestations of severe chronic AR are often the result of widened pulse pressure (ie, an exaggerated difference between systolic and diastolic blood pressure) because (1) elevated stroke volume exists during systole and (2) the incompetent aortic valve allows the diastolic pressure within the aorta to fall significantly.
