Diastolic blood flow. Pathline visualization of all blood flow involved in one cardiac cycle in the left ventricle (LV) of a healthy, 61 year old male at peak early LV filling (A), diastasis (B), and peak atrial contraction (C). In all panels a semitransparent three-chamber image provides anatomical orientation. The pathlines are color coded according to: Direct Flow, green; Retained Inflow, yellow; Delayed Ejection Flow, blue; Residual Volume, red. LA, Left Atrium; LV, Left Ventricle.
