My husband had HOCM and five blockages. He had his surgery nine months ago today, and I can’t begin to tell you the difference. The first two months he felt very little difference and questioned everything he went thru. Now, he would do it again knowing how great he feels. A year ago he was exhausted just coming in from the driveway. Mayo is the best for this condition, surgery. The staff is so fabulous I can’t rave enough about them. Get it done and move on with life.
