Congenital heart disease in adults, part 2

The treatment of congenital heart disease in adults is reviewed, focusing on heart disease that causes cyanosis. Cyanosis occurs when body tissues do not receive enough oxygenated blood. This usually occurs because blood returning to the heart for oxygenation by the lungs does not get oxygenated but is pumped back out of the heart to the rest of the body. The most common cause is a large opening in the muscle that separates the right and left sides of the heart. The treatment of Tetralogy of Fallot, Ebstein's anomaly, Eisenmenger's syndrome and transposition of the great arteries are discussed.
