Normally the clot is not removed and is allowed to organize naturally. However, your associated double vessel coronary artery disease may need surgery or angioplasty depending on the location of the block, the nature of the block and the arteries which are blocked i.e. whether the main artery called LAD is involved or not. I think such queries are very specific in nature and can only be answered definitively by your treating cardiologist after first hand view of the angiogram and on the net, we can only give your answers in generic terms.
