Hi, as the right side coronary circulation is dominant, stenosis of RCA greater than 70% is an indication for Coronary Artery Bypass Grafting. He also has blocks in the LCX and LAD.. So, surgery may be the option. This may again depend on his clinical symptoms and his general health condition. You will have to discuss the prognostic indications with his treating doctor before consenting for surgery. Regards.
Not sure but my husband had 5 bypasses before and it said RCA is totally occluded. He just had another cath and had stent placed. They mentioned the RCA being 100% occluded. Said they will not do anything to it. I too don't understand what they mean. Wish your dad the best.
