Figure 1

Multiple dynamic eccentric regurgitation jets in a patient in a 4 chamber (A-C) and 2 chamber (D-F) MPR during early (34 ms) (A, D), mid- (201 ms) (B, E) and late (302 ms)(C, F) systole (total RR 984 ms). The jet, visualized with a high velocity by blue streamlines, starts nearly perpendicular (90°) to the annulus (in A and D), but changes to a more lateral and anterior direction (in B and D). A second jet was observed in late systole (in C and F). Black dots show the annulus plane and the white dots represent the orientation of the plane perpendicular to the jet in which regurgitation is quantified (quantification is performed 1-2 cm more proximal to this plane). In B and E, angle measurements between annulus and regurgitation jet are illustrated.
