Parasternal long axis (PLAX) view showing mitral regurgitation (MR) jet into the left atrium. MR is seen as a bluish tongue shaped mosaic (multi colored) jet directed downwards into the left atrium, in the left panel. Aortic valve is seen as open and the mitral valve seen in closed position as it is a systolic frame.
Apical four chamber view on echocardiography showing a small bluish mosaic jet of MR into the left atrium across the closed mitral valve. This colour jet is consistent with a trivial MR as it occupies only a small portion of the left atrial area. Ideally one should sketch out the area of the left atrium and the MR jet to assess the ratio of the two and thereby the severity of mitral regurgitation. But practically this is seldom done in a busy echocardiography laboratory for a trivial MR as assessed visually (eyeballing!).
