What is a coronary artery fistula?

Also known as: CAF, congenital heart defect.

The coronary arteries are the oxygen rich blood vessels that deliver blood to the heart muscles.

A coronary artery fistula is a rare, abnormal, usually congenital (meaning a baby is born with it) defect where a coronary artery, rather than connecting to a coronary vein, incorrectly enters a heart chamber or different blood vessel.
