Streamline visualization (velocity encoded) of ‘typical clockwise’ right atrial vortex during late ventricular systole/atrial filling phase in a control subject viewed from the right sagittal aspect, demonstrating positioning of the planes and contours in the caval veins and associated flow waveform across the cardiac cycle (*peak systolic flow, _†peak diastolic flow, note negative SVC flow reflects directionality; flow magnitude only is reported in the results).
