Measurement of Phase-Contrast MRI mitral flow and lateral wall motion for Assessment of Diastolic Function in a Normal Collective
نویسندگان
چکیده
Introduction In approx. 50% of cases, heart failure is caused by an isolated diastolic dysfunction (DD) in the presence of a preserved systolic function but with comparably devastating outcome. Among others, echocardiography (EC) categorized DD mainly according to early (E-wave) and late (A-wave) diastolic mitral blood flow (MBF) as well as tissue-doppler imaging (TDI) showing characteristic S`-E`-A` lateral wall velocity patterns. Cardiovascular magnetic resonance (CMR) has excellent capabilities to assess blood flow and myocardial tissue motion using phase contrast (PC-CMR) imaging but has not been used to quantify DD similar to the EC approach.

Mri assessment of diastolic dysfunction using the echocardiographic criteria of diastolic mitral blood flow, lateral wall motion velocity and pulmonary vein flow
Introduction In echocardiography (EC), classification of diastolic dysfunction (DD) is widely accepted and mainly assessed using three criteria (figure1): mitral blood flow (MBF, E-A-curve), lateral wall velocity (LWV, S-E`-A`-curve) and pulmonary vein flow (PVF, S-D-AR-curve). With these three characteristic flow and velocity patterns and their ratios E/A, E/E ́ and S/D, regular diastolic funct...
متن کاملMRI assessment of diastolic dysfunction in comparison to transthoracic echocardiography
Background Over the last decade the interest in diastolic dysfunction has grown, due to the fact that at least half of all cases of newly diagnosed heart failure patients present with preserved ejection fraction. One of the most important tasks of cardiovascular imaging is the objective assessment of left ventricular (LV) systolic and diastolic function, which is routinely performed with standa...
متن کاملEvaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...

متن کاملDiastolic Function in Patients with Hypertrophic Cardiomyopathy: Evaluation Using the Phase-contrast MRI Measurement of Mitral Valve and Pulmonary Vein Flow Velocities
In patients with hypertrophic cardiomyopathy (HCM), diastolic dysfunction is common and most frequently assessed by the transmitral flow velocity pattern with the use of the pulsed Doppler technique (1-4). Transmitral inflow velocity pattern is determined by transmitral pressure gradient reflecting the status of myocardial relaxation and left atrial (LA) INTRODUCTION �Received; August 25, 2014�...
