CMR for the assessment of the severity of valvular regurgitation in patients with combined significant mitral regurgitation and aortic regurgitation. LV volume measurements in end-diastole (LV EDV) and end-systole (LV ESV) are performed using short-axis views cine-MRI. Then, the measurement of LV stroke volume (LVSV) is obtained by the formula: LVSV = LV EDV − LV ESV. By performing a 2D flow sequence 1 cm above the aortic valve, measurement of the volume of systolic anterograde flow in the aorta and the regurgitant volume (Ao RVol) can be performed. Finally, the mitral regurgitant volume (M RVol) is obtained by the following formula: M Rvol = LVSV − Ao stroke volume − Ao RVol.
