@bob720 I don't know where my response went to but I wanted to tell you . I had no other option but open heart surgery as the balloon first that was put in collapsed and my veins where to small for stints . This all took place in Pa . but now I live in So.Cal.
I guess I hit your REPLY box and not the Clapper who has 100% blockage. My doctor said anything more than three bypasses and you get bragging rights.
