Abstract

Introduction. Left venticular end diastolic pressure (LVEDP) is a important hemodynamic variable that is important to determination of cardiac function. LVEDP increases both in left ventricular systolic and diastolic dysfunction. Diagnosis and evaluation of heart failure and efficacy of drug and nondrug therapy, effect of other drugs on left ventricular functionand prognosis of heart patients is possible by measurement of LVEDP. The goal of this study is evaluation of accuracy of left atrial pressure (LAP) measured by Doppler Echocardiography in LVEDP estimation.Methods. In this study, 25 patients were selected that scheduled for left heart catheterization with any indications and diagnosis of mitral regurgitation (1+ or more) cofirmed with ventriculography in catheterization. LVEDP was directly measured by a left ventricular catheter and systolic blood pressure (SBP) by a mercurial manometer, then MR jet peak velocity was measured by echocardiography and with using of Bernolli equation and SBP, LAP was calculated, and by Pearson Correlation test, correlation coefficient between LVEDP and LAP was calculated.Results. Correlation test showed a direct correlation exists between LAP measured by Doppler Echocardiography and LVEDP measured by catheterization, and correlation coefficient was r=0.76. (P<0.001). This study also showed that on the basis of regression line equation (y on the basis of x) LVEDP on the basis of LAP can be estimated and predicted. (LVEDP=0.183+0.851 LAP).Discussion. Doppler Echocardiography is an acceptable procedure in estimation of LVEDP in patients with MR, in contrast to catheterization (Golden standard procedure) and since echocardiography is available, non invasive, repeatable, bedside procedure (if need) with low complications, Doppler Echocardiography is introduced as an available and accurate alternative procedure in LVEDP measurement in patients with MR and LVEDP as an available variable in bedside for evaluation, diagnosis and treatment of heart failure with MR.
