Transposition of the great vessels

Transposition of the great vessels

Overview

Transposition of the great vessels is a congenital heart defect in which the position of the two major vessels that carry blood away from the heart - the aorta and the pulmonary artery - is switched (transposed). This defect is classified as a cyanotic heart defect because the condition results in insufficiently oxygenated blood pumped to the body which leads to cyanosis (a bluish-purple coloration to the skin) and shortness of breath.
