“…This results in opening up of fistulous communications with the coronaries and initially results in bidirectional flow in coronaries, with reversal of flow into the aorta in systole. 5 The resultant to and fro flow leads to eventual occlusion of the communication with the aorta and coronary perfusion becomes dependent on the right ventricle which pumps relatively deoxygenated blood, a state called RVDCC. The more the myocardium that is RV dependent, the higher is the risk of myocardial dysfunction.…”
