Example of a vector flow mapping image of a healthy volunteer. a The strong clockwise rotating vortex and the weak counterclockwise rotating vortex are shown during early diastole. b The weak counterclockwise rotating vortex diminishes, and the strong clockwise rotating vortex is in the mid-cavity of the left ventricle during mid-diastole. c The clockwise rotating vortex is now in the base cavity of the left ventricle due to the atrial contraction during late diastole. d Vortex momentum facilitates the ejection flow during early systole. e All of the flow from the whole left ventricular cavity is directed to the left ventricular outflow tract
