Example of flow quantification. Retrospective valve tracking in a patient with the reformatting plane (white line) adjusted to the inflow during diastole (A) and perpendicular to the regurgitant jet during systole (C) with through-plane velocity of inflow (B red contour indicates LAVV flow, green contour traces a region within the free wall of the left ventricle for background correction) and the non-circular regurgitant jet (CI = 0.67) (D). In (E) the flow curve.
