Mitral Inflow E/A Ratio in Echocardiography: Measurement, Interpretation and Clinical Significance The mitral inflow E/A ratio is one of the fundamental parameters used in echocardiography to assess left ventricular (LV) diastolic function. It provides valuable information about ventricular relaxation, early diastolic filling and the contribution of atrial contraction to ventricular filling. Measured using pulsed-wave Doppler across the mitral valve, the E/A ratio is an essential component of the comprehensive assessment of diastolic function. However, its interpretation requires consideration of patient age, heart rate, loading conditions and other echocardiographic parameters. 1. What Is the Mitral Inflow E/A Ratio? During diastole, blood flows from the left atrium (LA) into the left ventricle (LV) through the mitral valve. This process produces two characteristic Doppler waves: E wave (Early filling wave): Represents early passive filling of the left ventricle following ...
