Session Title: Tisue Doppler, Speckle Tracking and Diastolic Function Abstract Category: 31. General Echocardiography: TTE Session-Poster Board Number: 1024-219 Authors: Jin Bae Lee, Kee SIk Kim, Byoung Kyu Kim, Myung Jun Seong, Young Soo Lee, Jae Kean Ryu, Ji Yong Choi, Sung Gug Chang, So Yeon Kim, Daegu Catholic University Medical Center, Daegu, South Korea Background: Classification of diastolic function is classified on the basis of the peak mitral flow velocity of early rapid filling wave (E), peak velocity of the early rapid filling wave, the E/A ratio and deceleration time (DT). This study was designed to compare diastolic filling patten and early transmitral flow velocity (E)/early diastolic velocity of mitral annulus (Em) and that’s correlation of left atrial volume index (LAVI) and pro-BNP Methods: A total 3547 consecutive patients were analyzed. Mitral inflow was assessed in a standard manner, E, A and DT were measured. Doppler tissue imaging of the mitral annulus was obtained from the apical 4-chamber view using a 1-2 mm sample volume placed in the septal mitral annulus. Early (Em) and late (Am) annulus velocities were measured in both sites and acquired data were averaged. LA volume index and pro-BNP was evaluated. Results: There are significant discrepency between mitral filling pattern and E/Em. Only 34% of normal filling was normal E/Em range and 26.3% of restrictive filling was normal E/Em. LAVI and Log pro-BNP were increasing with increasing E/Em grade but classic mitral filling pattenrn grade is no cosistancy with LAVI and Log pro-BNP increase. Conclusions: E/Em ratio allowed the identification of patient with diastolic heart failure more accurately than classic diastolic filling pattern.
