Optimal planimetry location for MRI-derived mitral inflow velocity assessment of diastolic function
نویسندگان
چکیده
Background Diastolic function is almost exclusively assessed using transthoracic echocardiography (TTE), however velocityencoded phase-contrast imaging permits diastolic evaluation with cardiac magnetic resonance (CMR). However, previous studies have utilized heterogeneous planimetric contour locations to measure mitral valve (MV) inflow velocities and the optimal contour is uncertain. We therefore evaluated CMR MV inflow velocities measured at various regions against TTE to identify the optimal method.

Background: Considering the association between cardiac abnormalities and non-alcoholic fatty liver disease (NAFLD), the present study aimed to evaluate the relationship between biopsy-proven NAFLD and functional echocardiographic parameters, including left ventricular (LV) global longitudinal strain (GLS) in asymptomatic individuals. Methods: Thirty asymptomatic patients with liver biopsy-prov...

Background Transthoracic echocardiography (TTE) provides noninvasive measures of diastolic left ventricular (LV) function by assessing mitral inflow and mitral annular motion. Given the excellent spatial and temporal resolution of CMR, we developed a novel method to calculate several correlative measures of diastolic and systolic LV function. The maximum velocity of the atrioventricular junctio...

Assessment of mitral annular tissue velocity plays an essential role in the evaluation of diastolic dysfunction. We have previously shown that mitral annular velocities can be derived from standard four-chamber cine SSFP images by automatically detecting and tracking the mitral valve insertion points [1]. However, this method has not been validated against tissue Doppler echocardiography, the s...

Background: Estimation of Left Ventricular End Diastolic Pressure (LVEDP) among patients with Mitral Stenosis (MS) helps to diagnose diastolic dysfunction and to explain their symptoms. However, Conventional Doppler measurements have limitation in predicting of LVEDP. This study sought to establish whether the correlation between measurements derived from Tissue Doppler echocardiography and LVE...
متن کاملMitral flow derived Doppler indices of left ventricular diastolic function.
AIMS Left ventricular diastolic dysfunction has been proposed as the basis of heart failure in patients with normal left ventricular systolic function. Doppler indices of mitral inflow have been widely used to diagnose this condition and have been shown to correlate well with increased left atrial pressure in patients with cardiovascular disease. We wanted to establish age-specific criteria for...
