Background: 3D echocardiography derived volumetric data can be used to generate left ventricular volume time curves and has the potential to elucidate aspects of contractility, systolic and diastolic function in normal and disease states. We sought to establish the validity and reproducibility of these volume-time curves and apply novel parameters derived from these curves to a clinical population.
Methods: Consecutive patients, who underwent cardiac MRI and echocardiography within 12 hours, were
used to compare volume-time curves. Inter- and intra observer variability of the 3D echocardiography volume-time curves was assessed. Peak emptying rates, peak filling rates, and peak systolic acceleration were measured in a normal population (normal Ejection Fraction (EF) and no significant valvular disease) and their change with age was eva..
