Key result
Patients with a dilated left ventricle exhibited a distinct circular flow pattern persisting through diastole, with significantly lower ejection fraction (31% vs 61%, P<0.001) compared to controls.
Why the study?
Does magnetic resonance velocity vector mapping identify differences in left ventricular flow patterns between patients with dilated ischemic left ventricles and healthy volunteers?
Population
11 patients with dilated left ventricle resulting from coronary artery disease and 10 healthy volunteers
Comparison
Magnetic resonance velocity vector mapping vs Healthy volunteers

Distinct circular diastolic flow in dilated LV is hypothesis-generating; leaves open clinical utility of MR velocity mapping.
Case-Control (n=21)
Does magnetic resonance velocity vector mapping identify differences in left ventricular flow patterns between patients with dilated ischemic left ventricles and healthy volunteers?
p-value: p=<.001
Magnetic resonance velocity vector mapping can effectively visualize and quantify altered diastolic flow patterns in patients with dilated ischemic left ventricles.
Raad Mohiaddin (1995) conducted a case-control in Dilated left ventricle resulting from coronary artery disease (n=21). Dilated left ventricle from coronary artery disease vs. Healthy volunteers was evaluated on Left ventricular flow patterns and hemodynamic parameters (p=<.001). Patients with a dilated left ventricle exhibited a distinct circular flow pattern persisting through diastole, with significantly lower ejection fraction (31% vs 61%, P<0.001) compared to controls.
