RCA: The RCA supplies the right atrium and ventricle. A complete blockage will cause a major heart attack. A thrombosis is NOT a dormant situation. It is restricting flow. How much restriction guides therapy. At a minimum medical therapy would be necessary (aspirin, plavix, (clopidogrel) statins etc).

No: A thrombosis, or blood clot, does not "lie dormant". A thrombosis of the RCA would develop rather suddenly as a biochemical response to a cholesterol-based, calcium-coated plaque that "cracks". Just as when skin is cut, platelet blood cells and other chemicals come together to "heal" the break in the plaque by creating a thrombosis (clot) that can then block blood flow to cause a heart attack.
