Hi Cathy. I was at 90% on the LAD about ten years ago. My surgeon went with multi vessel stenting instead of bypass. after experiencing severe breathing problems in January, I underwent another cath only to find out that the two stents that were in my LAD had collapsed. So they re-opened them with two more new stents. I feel bypass would be a much better solution than to just keep stenting. When I mentioned this to the doctor, he said they won't do by pass for just one vessel (the LAD). If you can, go with the bypass. I think everyday what's going to happen next is I get another 90-95% blockage in my LAD.
