Stumpy, don't worry buddy...It's a very common procedure now but the worriment before is understandable...My uncle is 74 and just had a heart valve replacement much like a stent...Took it in through the groin and expanded it right in place...In and out in 2 days !!! Medicine has come a long way and most don't keep up with the latest tech around these procedures,the stent is an easy one to accomplish...The people I know that had it done saw an immediate improvement and wished it was done earlier but it sneaks up on you over the years and most figure it's just the way things are with getting old...You'll be fine ...Good Luck !!
