doppler tissue imaging: a non-invasive technique for estimation of left ventricular end diastolic pressure in severe mitral regurgitation
background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...
متن کاملassessment of subclinical left ventricular dysfunction in patients with chronic mitral regurgitation using torsional parameters described by tissue doppler imaging
background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...
متن کاملPulsed tissue Doppler imaging detects early myocardial dysfunction in asymptomatic patients with severe mitral regurgitation.
OBJECTIVE To assess whether tissue Doppler myocardial imaging (TDI) indices can predict postoperative left ventricular function in patients with mitral regurgitation (MR) after surgical correction. METHODS 84 patients (mean (SD) age 54.3 (10.8) years) with asymptomatic severe MR, an end systolic diameter < 45 mm, and an ejection fraction (EF) > 60% were subdivided in two groups: 43 patients w...
متن کاملLetter regarding article by Diwan et al, "Doppler estimation of left ventricular filling pressures in patients with mitral valve disease".
BACKGROUND Conventional Doppler measurements have limitations in the prediction of left atrial pressure (LAP) in patients with mitral valve disease (MVD), given the confounding effect of valve area, left ventricular (LV) relaxation, and stiffness. However, the time interval between the onset of early diastolic mitral inflow velocity (E) and annular early diastolic velocity (Ea) by tissue Dopple...
متن کاملtissue doppler imaging findings including prominent s wave in patients with mitral valve prolapse syndrome
conclusions sm wave in tdi is prominent and significantly high in mvp syndrome. also, our study showed some degree of diastolic dysfunction in mvp patients. results seventy-five patients (48 females) at a mean age of 26.5 ± 9.4 years and 50 individuals (32 females) at a mean age of 27.1 ± 8.3 years were enrolled in the study. as the important results of our study, sm wave was much more prominen...
