Everything went well with Dad's appointment. We were really worried; it turned out that the blockage was much worse than the doctor thought. He said that if he couldn't open it with the balloon and stents, Dad would have to get the bypass redone. Thankfully, the doctor was able to open up the blocked bypass with stents. Dad's staying overnight in the hospital and should be home tomorrow. He may actually be able to go back to work as early as Monday.
