Evaluate the sensitivity and specificity echocardiography in trans-Doppler and tissue Doppler method in the estimation of left ventricular end-diastolic pressure

Non-invasive survey of left ventricular end-diastolic pressure (LVEDP) by transmitral Doppler echocardiography and tissue Doppler imaging carries important information about left ventricular diastolic function in chosen subsets of patients. This study is planned to assess whether mitral annular velocities (lateral annulus) as assessed by tissue Doppler imaging and transmitral Doppler echocardiography are associated with invasive measures of left ventricular end diastolic pressure and also the estimation of sensitivity and specificity of these methods. One hundred ten consecutive patients admitted to cardiac catheterization underwent simultaneous Doppler interrogation measurements of left ventricular pressure were obtained with fluid-filled pressure. The E/Ea ratio associated well with LVEDP (P
