Angiographic demonstration of extracardiac coronary supply after coronary artery bypass surgery. (A) Posterior-anterior projection of the left internal mammary artery bypass (marked by a *) on the left anterior descending coronary artery (LAD, marked by a #). Upstream of the bypass anastomosis, retrograde filling of the LAD is incomplete revealing coronary occlusion, which triggered the arteriogenesis of the pericardiacophrenic branch (marked by a +) (B) Lateral projection using the same markers revealing the connection of the pericardiacophrenic branch with the third diagonal branch (marked by III).
