Therefore, delivery of substrates and wash-out of metabolites are believed to be accomplished by capillary perfusion. Several investigators reported inhomogeneous distribution and low capillary perfusion efficiency of retrograde cardioplegia. The coronary sinus drains about 75% of coronary venous blood. 7 These veins are distributed throughout the right ventricle. 10 Antegrade cardioplegia also distributes inhomogeneously unless coronary artery is free of stenosis. 13 Retrograde cardioplegia is delivered to the right ventricle through veno-venous networks.
There is also an acute angle (black arrow) between the inferior vena cava (VC) and the cs. Additionally marked (1) the right ventricle, (2) left ventricle, (3) aorta and (4) body of a vertebra. bicuspid valve. In 2% of the cases we found a tricuspid valve; in 1% there was a valve-complex with two unicuspid valves following one another (Figs. 7 The entrance of the cs into the right atrium was guarded by a more or less complete and sufficient fold, the Thebesian valve. In 19% of the cases the ostium was valveless.
