Mitral inflow and mitral annular motion velocities in patients with mitral annular calcification: evaluation by pulsed Doppler echocardiography and pulsed Doppler tissue imaging.
AIMS We evaluated the relationship between the mitral inflow velocities by pulsed Doppler echocardiography and mitral annular motion velocities by pulsed Doppler tissue imaging in patients with mitral annular calcification. METHODS AND RESULTS Fifty-three patients with mitral annular calcification were divided into two groups: severe mitral annular calcification (n=15, mitral annular calcific...
متن کاملAutomatic Mitral Valve Inflow Measurements from Doppler Echocardiography
Doppler echocardiography is widely used for functional assessment of heart valves such as mitral valve. In current clinical work flow, to extract Doppler measurements, the envelopes of acquired Doppler spectra are manually traced. We propose a robust algorithm for automatically tracing the envelopes of mitral valve inflow Doppler spectra, which exhibit a large amount of variations in envelope s...
متن کاملInfluence of age and BSA in tissue Doppler imaging velocities.
Sir, T Doppler imaging (TDI) is sensitive in detecting early myocardial dysfunction. There are, however, great variations in normal values observed by different workers. This could be because of impact of demographic variables on TDI velocities. We studied 64 normal persons with clinic BP of 120/80mmhg or less and devoid of other cardiovascular risk factors. Mmode, 2-D, pulsed Doppler and tissu...
متن کاملImpact of stroke volume on mitral annular velocities derived from tissue Doppler imaging.
M itral annular velocities derived from pulsed tissue Doppler imaging (TDI) were recently demonstrated to complement the analysis of systolic and diastolic left ventricular (LV) performance in different clinical settings. 2 The early diastolic mitral annular velocity (E9) was found to behave as a preload independent index of relaxation. The mitral E/E9 ratio (that is, the mitral E velocity corr...
متن کاملHemodynamic determinants of the mitral annulus diastolic velocities by tissue Doppler.
OBJECTIVES Our goal was to identify the hemodynamic determinants of the mitral annulus (MA) diastolic velocities by tissue Doppler. BACKGROUND The MA diastolic velocities are promising indexes of left ventricular (LV) diastolic function. However, their hemodynamic determinants have not yet been evaluated. METHODS Ten adult mongrel dogs underwent left atrial (LA) and LV pressure measurements...
