A 13-year-old girl with surgically corrected complete transposition of the great arteries died suddenly while walking to school. Postmortem examination revealed endodermal heterotopia of the atrioventricular node, a condition not previously associated with transposition of the great arteries. New immunohistochemical observations are described, and the embryogenesis of the condition and its association with complete transposition are discussed.

D001283	Atrioventricular Node	A small nodular mass of specialized muscle fibers located in the interatrial septum near the opening of the coronary sinus. It gives rise to the atrioventricular bundle of the conduction system of the heart.

D014188	Transposition of Great Vessels	A congenital cardiovascular malformation in which the AORTA arises entirely from the RIGHT VENTRICLE, and the PULMONARY ARTERY arises from the LEFT VENTRICLE. Consequently, the pulmonary and the systemic circulations are parallel and not sequential, so that the venous return from the peripheral circulation is re-circulated by the right ventricle via aorta to the systemic circulation without being oxygenated in the lungs. This is a potentially lethal form of heart disease in newborns and infants.

D017809	Fatal Outcome	Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.	Fatal Outcomes,Outcome, Fatal,Outcomes, Fatal
