Washington Health Agencies Are Practicing Medicine: The Case Of A Sick Heart
The heart has four chambers, each separated by a supple valve. As people age, these valves narrow, and eventually can fail. The aortic valve often takes the brunt of the damage. Repairing it used to require risky open-heart surgery. Two years ago, after a lengthy delay, the Food and Drug Administration (FDA) approved a device called Sapien -- developed by Edwards Lifesciences (EW:NYSE) -- that allows doctors to replace a damaged aortic valve through a small incision made in a patient’s leg.
