Recent advances in cardiac magnetic resonance imaging have allowed for characterization of blood flow in the human right ventricle (RV) and right atrium (RA), including calculation of vorticity and circulation, and qualitative visual assessment of coherent flow patterns. An overview of the methods and results of a recent study of the qualitative and quantitative differences in RV and RA vorticity and coherent flow patterns between healthy human subjects and patients with right ventricular diastolic dysfunction will be presented.
