Valvular Cardiomyopathy: The Value of Cardiovascular Magnetic Resonance Imaging

Figure 4

A case of mitral regurgitation assessment using four-dimensional flow CMR. (a) Two-chamber cine view with velocity overlay demonstrating mitral regurgitation (blue flow in the left atrium). (b) Four-chamber cine view shows the same mitral regurgitation jet which is swirling in the whole left atrium. (c) A three-chamber cine view used to quantify aortic stroke volume by valve tracking. (d) Three-dimensional streamlines of blood flow during systole demonstrating aortic forward flow and the mitral regurgitation swirling in the left atrium.
