SIGNIFICANCE OF NEW SIMPLE ECHOCARDIOGRAPHIC PARAMETER FOR MITRAL REGURGITATION SEVERITY IN ATRIAL FIBRILLATION

Left ventricular early inflow-outflow index (LVEIO), which is calculated by dividing the mitral E-wave velocity by the LV outflow velocity time integral has been proposed as a parameter for severity of mitral regurgitation (MR). We have reported that LVEIO is a useful and simple method to diagnose
