BACKGROUND Early detection of diastolic dysfunction is crucial for patients with incipient heart failure. Although this evaluation could be performed from phase-contrast (PC) cardiovascular magnetic resonance (CMR) data, its usefulness in clinical routine is not yet established, mainly because the interpretation of such data remains mostly based on manual… (More)
Early detection of diastolic dysfunction is crucial for patients with incipient heart failure. Our goal was to develop a robust process to automatically estimate diastolic parameters from phase-contrast cardiovascular magnetic resonance (PC-CMR) data and to test their ability to characterize left ventricular (LV) dysfunction. We studied 53 subjects (35… (More)
3D myocardial wall stress assessed by cardiac magnetic resonance and non invasive aortic blood pressure in patients with severe aortic valve stenosis
Although few studies demonstrated the ability of MRI dynamic anatomical sequences to assess right ventricular (RV) diastolic function, no data are available for velocity-encoded MRI (VE-MRI). Accordingly, our aim was to evaluate RV diastolic function from VE-MRI, as compared to reference Doppler echocardiography. We studied 109 healthy individuals (67 men,… (More)
Relationship with age and comparison of phase-contrast -CMR and Doppler-echocardiography derived left ventricular diastolic function parameters in asympto-matic individuals with preserved ejection fraction.
Accurate quantification of aortic valve stenosis (AVS) is crucial for relevant patients management. We hypothesized that automated analysis of phase-contrast cardiovascular magnetic resonance (PC-CMR) data might provide accurate AVS evaluation in agreement with the well established transthoracic echocardiography (TTE). We studied 74 subjects (53 AVS… (More)
Objectives To compare phase contrast magnetic resonance (PCMR) evaluation of tricuspid inflow against echocardiographic measurements and to assess age-related changes in right ventricular (RV) diastolic function evaluated by both techniques.
Objective To evaluate the direct relation between proximal aortic function and left ventricular diastolic function in individuals with normal LVEF free of overt cardiovascular disease.
