Figure 16 Inadvertent cardiac phlebography through the Thebesian network. A, B: Right anterior oblique views in systole (A) and diastole (B) during left ventriculography show a minor subendocardial staining (arrowhead) and opacification of a posterior interventricular vein (arrows), due to opening of a 'functional' fistula between the left ventricle and the cardiac vein through the Thebesian network.
