Thanks for sharing Alcie
From my understanding, consideration would be given by a cardiologist re how long the vessel has been totally occluded If there is 100% occlusion and no signs of a deficit supply of blood to the area normally served by the LAD, an assumption may be made that there is a natural bypass (collateral vessels) that has developed . There is also the possiblity if the LAD is
opened, the lower resistance of blood flow through the LAD can take away the blood flow through the collaterals.
God bless interventional cardiologists who have turned poor outcome situations in to good outcomes with their skills and knowledge.
