trans·po·si·tion of the great ves·sels

congenital malformation in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle resulting in two separate and parallel circulations. The condition is lethal unless some communication exists between the systemic and pulmonic circulation after birth; otherwise, unoxygenated venous blood inappropriately enters the systemic circulation, and oxygenated pulmonary venous blood is inappropriately directed to the pulmonary circulation. The life-sustaining communication may be an intraatrial passage or a patent ductus arteriosus.

(trans'pŏ-zish'ŭn grāt ves'ĕlz)
Congenital malformation in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle, resulting in two separate and parallel circulations. The condition is lethal unless some communication exists between the systemic and pulmonic circulation after birth; the life-sustaining communication may be an abnormal interatrial passage or a patent ductus arteriosus.

transposition of the great vessels

One of the types of congenital heart disease. In this condition, the AORTA, the main supply artery of the body, is wrongly connected to the right ventricle, which normally pumps blood returning from the body to the lungs. The pulmonary artery is connected to the left ventricle. As a result, the lungs are effectively bypassed and the blood supplied to the body is insufficiently oxygenated. There is blueness of the skin (cyanosis), breathlessness and failure to thrive. Heart surgery is usually necessary.
