Aortic regurgitation (AR) – trivial – on Doppler interrogation from the apical five chamber view (upper panel). Incomplete image of the jet is obtained when the regurgitant flow is less as in trivial or mild AR. The jet seen below the baseline is the forward aortic flow in systole, whereas AR occurs in diastole. The forward velocity is about 1.2 m/sec, indicating the absence of any associated aortic stenosis. The colour bar on the top right indicates that the Nyquist limit of the colour Doppler imaging has been set at 60 cm /sec. The scale on the right lower side is the Doppler scale in meters per second, with positive values above the baseline and negative values below the baseline. In the apical five chamber view, the aortic forward flow is away from the transducer and is depicted negative while the regurgitant flow is towards the transducer and depicted positive.
