I'm having trouble wrapping my mind around what seems like a straight-forward concept: but how does aortic regurgitation increase end diastolic volume? If the LV fills with a certain amount of blood based on the size of the chamber, how does regurgitation increase the amount of blood that can occupy it? Is the pressure of regurgitation enough to force more blood into the LV in excess of the amount of blood flowing in from the mitral valve during diastole? Why does aortic regurgitation increase EDV rather than simply filling the LV more quickly with no increase in EDV?
