Examples of anastomotic structures in different views. G: Graft; CA. Coronary artery. (A) Longitudinal view of an end-to-side anastomosis where the location of the heel, middle, and toe sections of the anastomosis are shown. (B) A transverse view of the heel containing a graft and a coronary artery. (C) Transverse view of the mid-section of the anastomosis, where the red line represents the width of the anastomotic orifice in the frame. The yellow contours represent manual segmentations of the anastomotic vessel structures
