A couple things were different about my angioplasty. I had an airbag clamp gizmo they strapped to my leg to prevent bleeding. I think it was called a cathclamp. No being sandbag strapped to the table after surgery, but I had to wear it for 8 hours.
I could be very wrong, but I don't remember it taking 20 minutes for the Doc to remove my cath. It was all very bang-zoom. I was in and out in under an hour.
