Operations on the coronary vessels: Other revascularization of the heart: Revascularization with free internal mammary artery graft (IMA graft)

You had a bypass operation.

The heart is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart. When coronary vessels have narrowed or closed, the blood supply in the heart is no longer right.

Bypass surgery involves using replacement blood vessels to bridge narrowed or closed coronary vessels. The replacement blood vessels then direct the blood past the locations concerned. As a result, the heart should be better supplied with blood. In your case the locations concerned were bridged using a replacement blood vessel from your own body.

In your case an artery was used as the replacement blood vessel. Arteries are blood vessels that transport blood away from the heart. They supply all the tissue in the body with oxygen-rich blood. The replacement artery comes from your chest.
