Cardiovascular System - Transposition of the Great Vessels
Characterized by aorta arising from right ventricle and pulmonary artery from the left ventricle and often associated with other cardiac abnormalities (e.g. ventricular septal defect).
- International Classification of Diseases code 745.1
- Australian national rate (1982-1992) 3.6/10,000 births.
- Of 988 infants 4.1% were stillborn and 23.2% liveborn died during neonatal period.
- slightly more common in twin births than singleton.

Some Recent Findings
The morbid anatomy of some of the most important parts of the human body (1833)
- "A very singular Malformation of the Heart, in a child about two months old, came, some time ago, into my possession : the aorta arose out of the right ventricle, and the pulmonary artery out of the left. There was no communication between the one vessel and the other, except through the small remains of the ductus arteriosus, which was just large enough to admit a crow quill. The foramen ovale was a little more closed than in a child newly born. The heart was of the common size for a child of two months old, and, except for the circumstances which have been stated, it had nothing remarkable in its structure. In this child florid blood must have always been circulating between the lungs and the left side of the heart, except for the admixture of the dark blood which passed through the small communication of the foramen ovale ; and dark blood must have been always circulating between the right side of the heart and the general mass of the body, except for the very small quantity of florid blood which passed into the aorta by the remains of the ductus arteriosus. Life must, therefore, have been supported for a very considerable length of time with hardly any florid blood distributed over the body."
- "The aorta arises from the fleshy part of the base of the right ventricle, at its left portion, where it presents itself in front, being quite uncovered by the pulmonary artery, and is situate between this vessel and the right auricle."

International Classification of Diseases
ICD-10-AM codes: Q20.1, Q20.3, Q20.5
ICD-9-BPA codes: 745.10–745.19
(ICD) The World Health Organization's classification used worldwide to classify the causes of death. The current version is ICD-10 (1990) that is due for replacement by ICD-11 (2011). A modified version, Australian modification of ICD-10 (ICD-10-AM), is used to classify diagnoses in Australian hospitals. Within this classification "congenital malformations, deformations and chromosomal abnormalities" are (Q00-Q99) but excludes "inborn errors of metabolism" (E70-E90).

Heart defects and preterm birth are the most common causes of neonatal and infant death. The long-term development of the heart combined with extensive remodelling and post-natal changes in circulation lead to an abundance of abnormalities associated with this system.
A UK study literature showed that preterm infants have more than twice as many cardiovascular malformations (5.1 / 1000 term infants and 12.5 / 1000 preterm infants) as do infants born at term and that 16% of all infants with cardiovascular malformations are preterm. (0.4% of live births occur at greater than 28 weeks of gestation, 0.9% at 28 to 31 weeks, and 6% at 32 to 36 weeks. Overall, 7.3% of live-born infants are preterm)
"Baltimore-Washington Infant Study data on live-born cases and controls (1981-1989) was reanalyzed for potential environmental and genetic risk-factor associations in complete atrioventricular septal defects AVSD (n = 213), with separate comparisons to the atrial (n = 75) and the ventricular (n = 32) forms of partial AVSD. ...Maternal diabetes constituted a potentially preventable risk factor for the most severe, complete form of AVSD." 
In addition, there are in several congenital abnormalities that exist in adults (bicuspid aortic valve, mitral valve prolapse, and partial anomalous pulmonary venous connection) which may not be clinically recognized.
