Multiple dynamic eccentric regurgitant jets. In one subjects in 4-chamber (A, C, E) and 2-chamber (B, D, F) view during early- (34 ms) (A,B), mid- (201 ms) (C,D) and late (302 ms) (E,F) systole (total RR 984 ms). The jet starts nearly perpendicular to the annulus (A, B), but changes to a more lateral (C) and anterior direction (D). A second jet was observed in late systole (E). Black dots show the annulus plane and the white dots the plane perpendicular to the jet. In plane (C, D), the angle measurements are illustrated between annulus and regurgitant jet.
