The regurgitant jet occurs during diastole toward the left ventricular cavity. From the 4 chamber or apical views, the color signal is primarily displayed as red-yellow, since its direction is toward the transducer and the jet can be distinguished from the mitral diastolic inflow. The long axis view can show the difference between mild regurgitation, which has a narrow base and short jet, compared to severe with broad base and long jet extent. The force in the latter may show presystolic closure on M-mode tracing.
