Figure/Graphic 1: LAEF (Left Atrial Ejection Force) The method for calculating the left atrial ejection force. Left panel shows the schema of four chamber view on twodimensional echocardiogram. As shown by arrow, mitral valve dimension (MVD) was measured, and mitral valve area (MVA) was calculated as a circle. Right panel shows the schema of transmitral flow velocity on the pulsed wave Doppler (PWD). Left atrial ejection force (LAEF) was calculated using the final equation. |
