Global flow-volume estimates loops in patients with severe left sided valvular disease. (A) Note peak systolic flow occurring at a lower relative ventricular volume in systole (arrow); (B) Note peak diastolic flow at a higher relative ventricular volume in diastole (arrow); (C) Note complex diastolic flow-volume estimates relationships in diastole in a patient with aortic regurgitation with altered early and late diastolic filling (arrows).
