From: First-phase ejection fraction by cardiovascular magnetic resonance predicts outcomes in aortic stenosis

Fig. 1

Representative cardiovascular magnetic resonance (CMR) images and measures of aortic valve flow and left ventricular (LV) volume from a patient in the series. Left ventricular volume was measured from CMR short-axis stack 3D, aortic valve flow was measured from phase contrast flow images and time to peak aortic valve flow was derived from the aortic valve flow-time curve. First-phase ejection fraction (EF1) was then calculated using equation: EF1 = (EDV-V1)/EDV%, where EDV is end-diastolic volume and V1 is volume at time of peak aortic valve flow
