Congenitally Corrected Transposition of the Great Arteries

A rare heart defect that occurs when the HEART VENTRICLES and attached valves, the MITRAL VALVE and the TRICUSPID VALVE are reversed so that the AORTA and the PULMONARY ARTERY are connected to the wrong ventricle. Although the heart valves and the two great arteries, the PULMONARY ARTERY and the AORTA are transposed, the blood flows to the correct place because the ventricles are also reversed and therefore corrects the transposition. It often occurs with other structural heart abnormalities.

Abstract

A rare heart defect that occurs when the HEART VENTRICLES and attached valves, the MITRAL VALVE and the TRICUSPID VALVE are reversed so that the AORTA and the PULMONARY ARTERY are connected to the wrong ventricle. Although the heart valves and the two great arteries, the PULMONARY ARTERY and the AORTA are transposed, the blood flows to the correct place because the ventricles are also reversed and therefore corrects the transposition. It often occurs with other structural heart abnormalities.
