- Heart rate, stroke volume, and cardiac output were calculated from the aortic flow and from left ventricular volume segmentations. Regurgitation fraction was calculated from the aortic flow, and ejection fraction from the volumetric measurements. Aortic annulus diameters were measured during peak systole
