Value of conventional and tissue Doppler echocardiography in the estimation of left ventricular filling pressure

Various conventional and tissue Doppler parameters have been proposed for the estimation of left ventricular filling pressure. To assess the utility of several conventional and tissue Doppler parameters in the estimation of left ventricular end diastolic pressure (LVEDP). Among 40 consecutive patients LVEDP was correlated with pulsed Doppler of mitral inflow and pulsed tissue Doppler of lateral mitral annulus. Among all studied Doppler variables, E′/A′ ratio showed the most significant correlation with LVEDP (r=0.612, p15mm Hg) with a positive predictive value of 100%. On the other hand, an E/E′ ratio of
