-87-year-old John Grigsby's doctor put him in the top predicament 2 years ago.
-He said I give you 3 to 6 months of the outside to live, more likely 3 months.
-He needed a new aortic valve, but wasn't a good candidate for traditional open-heart surgery.
-You had the triple bypass.
You had stents put in.
You've got diabetes.
You're recovering from congestive heart failure.
-This is daughter Gloria.
-But that laundry list combined with his age
made him the perfect candidate for Edwards Lifesciences' trial SAPIEN valve that doesn't require any surgery.
-Give me any chance I can, I enjoy life.
I wanna keep living.
-It's mounted inside this metal frame, and this metal frame is able to be crushed or what we call crimped and put on a balloon catheter, which is a small tube and tread it up from an artery in the leg or put through the tip of the heart.
Michael Mack is the chief of cardiac surgery for the Baylor Healthcare System in Dallas.
He was also one of 8 doctors overseeing the FDA
trials for the SAPIEN.
-This has opened up a whole new area of treatment with patients with a fatal and lethal disease that previously were never referred for surgery.
-Grigsby received his new valve in January 2010 and was up and walking that same day.
-To be able to replace somebody's heart valve without doing an operation to cut them open even 15 years ago, I couldn't have imagined that happening.
-And now, almost 2 years later, he still feels great.
-There's no problem.
So, I'm thrilled.
It saved my life.
-And now that the valve is FDA-approved, it has the chance to save someone else's life too.
