I have had a totally blocked LAD first known 7 years ago. It is not necessarily a deatg sentence. As a vessel becomes blocked over a period of time there can be collateral vessel development that helps supply blood to areas that is reduced as the blockage increases. That is my experience, and I am sure there are others with the same result.
There are different configurations of blood vessels and the areas that are perfused. There is the right dominant configuration or left dominate or combination thereof. In a left dominant heart, the entire interventricular septum is supplied by branches of the left coronary artery and the most frequently blocked coronary artery.
The ventricular septum is the wall that separates the right and left ventricles.
The septum serves as a pathway for electrical impulses that originate in the right atrium and travel down the septum and then break away into the right and left ventricals to contract the heart's pumping chambers.
If there is a heart attack from a clot obstruction, etc. of the LAD that will immediately disrupt the pathways of impulses to contract the heart and cardiac arrest will occur.
