Quantification of mitral annular excursion from cine MRI and validated by Doppler echocardiography

چکیده
Background Mitral annular plane systolic excursion (MAPSE) reflects longitudinal left ventricular function, predicts survival in heart failure patients and provides a sensitive marker of early systolic dysfunction in hypertensive patients with normal ejection fraction (EF). Doppler mitral annulus velocity (e’) in early diastole predicts cardiac mortality, differentiates diseases and estimates filling pressures. We present a practical technique that facilitates measuring atrioventricular junction (AVJ) motion throughout the cardiac cycle from cine cardiac magnetic resonance (CMR) and correlate these measurements with EF and echocardiographydetermined e’.

Mitral valve annular velocity measurements derived from cine MRI: validation against Doppler echocardiography
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...
متن کاملClinical Application of Cine-MRI in the Visual Assessment of Mitral Regurgitation Compared to Echocardiography and Cardiac Catheterization
BACKGROUND Detecting and quantifying the severity of mitral regurgitation is essential for risk stratification and clinical decision-making regarding timing of surgery. Our objective was to assess specific visual parameters by cine-magnetic resonance imaging (MRI) in the determination of the severity of mitral regurgitation and to compare it to previously validated imaging modalities: echocardi...
متن کاملA real-time 3-dimensional digital Doppler method for measurement of flow rate and volume through mitral valve in children: a validation study compared with magnetic resonance imaging.
We developed and assessed a real-time 3-dimensional (3D) digital Doppler method for measurement of flow volumes through the mitral valve in children. A total of 13 children (aged 10.46 +/- 2.5 years; 8 boys/5 girls) were enrolled. An ultrasound system (Sonos 7500, Philips, Andover, Mass) was used to acquire raw 3D velocity data for flow measurement based on Gaussian control surface theorem [flo...
متن کاملMethods for assessment of left ventricular systolic function in technically difficult patients with poor imaging quality.
The assessment of left ventricular (LV) systolic function is often the most important information obtained during clinical echocardiography. Although LV systolic function may be visually estimated in many patients with or without contrast opacification, technically difficult patients may require alternative methods for evaluating LV systolic function. In this review, the authors describe severa...
متن کاملReference values of mitral and tricuspid annular plane systolic excursion for the evaluation of left and right ventricular performance
Background Mitral annular plane systolic excursion (MAPSE) and tricuspid annular plane systolic excursion (TAPSE) correlate with the left and right ventricular (LV,RV) ejection fraction as well as with the prognosis of patients with heart failure. Furthermore, M/TAPSE are sensitive markers for impaired longitudinal function which can be the earliest marker of myocardial dysfunction in cardiomyo...
