A new study gives a big boost to fixing a bad aortic valve, the heart's main gate, without open-heart surgery. Survival rates were better one year later for people who had a new valve placed through a tube into an artery instead. Earlier this year, the CoreValve was also approved for treating people at too high risk to have surgery.
