Even when IV volumes can be measured, this may not be an optimal marker because the relationship between ventricular end-diastolic volume
and stroke volume is also influenced by ventricular contractility (Figure 2).

However Levis (13) found a high correlation between radiographic cardiac frontal area and left ventricular end-diastolic volume
in patients with pure aortic valve insufficiency.
As regurgitation, particularly severe regurgitation, becomes chronic, the left ventricular end-diastolic volume
increases and the end-systolic volume returns to normal (1).
Ventricular volumes were corrected for body surface area; LV end-systolic volume index and LV end-diastolic volume
index were quantified.
