Coronary artery and veins are married life long . . . with a purpose !

Cardiologist are always worried about the supply side of coronary blood flow. It’s fair enough, we can condone our brain for this one way thinking , afterall arterial supply remain the life-line for the heart. Some of us could (should) realise the importance of these  humble coronary veins which are anatomically and physiologically tied together.Its existence is as unique as their arterial counterpart.Coronary blood flow of about 250 ml traverses both the arms every minute.Imagine the scenario if the veins refuse to clear the blood from previous cardiac cycle . . . total hemodynamic chaos right ? Luckily such situations are rare ! See how the the two coronary arteries and its branches interwine with the 4 major coronary veins. J. M. Bourgery from Atlas of Human Anatomy and Surgery / Atlas d’antomie Humaine et de Chirurgie by Jean Marc Bourgery (1797-1849) Los Angeles: Taschen, 2005. Atlas Case QM 25 .B67 2005 Is the LAD flow coupled with Great cardiac venous flow ? It is curious to see the LAD  hugging its spouse great cardiac vein within the anterior Inter-ventricular groove , but directing the flow exactly doing opposite direction . One should  wonder is it the same stream of blood from LAD ?(Near 100% So2) goes out into myocardial tissue comes back with 30 % *saturation in GCV ? If this is true , one can measure the “LAD micro-circulatory bed” integrity by computing the arrival time of levo phase blood in GCV.
