Coronary venous anatomy. a Volume-rendered reconstruction of the heart. Great cardiac vein (GCV) and coronary sinus (CS) run along the atrioventricular groove. The first tributary, posterior interventricular vein (PIV) passes in the posterior interventricular groove, along with PDA of right coronary artery. The other tributaries of the CS are the posterolateral vein (PLV) and left marginal vein (LMV). b Volume rendered CT image in a 72-year-old man with myocardial infarction shows absence of both the posterolateral and left marginal veins
