Complete Health Indicator Report of Birth Defects: Prevalence of Transposition of the Great Arteries (Vessels) per 10,000 Live Births


Transposition of the great arteries (TGA) is a heart condition that is present at birth, and often is called a congenital heart defect. TGA occurs when the two main arteries going out of the heart--the pulmonary artery and the aorta--are switched in position, or "transposed". Prevalence of TGA is the number of live-born infants with TGA per 10,000 live born infants. (Live-born infants are the infants born with any evidence of life).

Data Interpretation Issues

In January 2000, birth defects became a reportable condition in New Mexico; however, birth defects were collected prior to this date. The first year of consistent data is 1998. However, data for transpostion of the great arteries (TGA) were not collected consistently until 2004. For TGA data, the most recent year of analyzed data is 2011. Data are collected on live births occurring in-state to NM residents. Therefore, live births that occur in NM among out-of-state residents are excluded. Case finding/identification occurs through review of birth and death certificates, hospital discharge diagnoses, records from pediatric specialists and prenatal diagnostic providers. Birth defect cases are ascertained up to age 4; however, the majority of diagnoses are made by age 1.

Why Is This Important?

Birth defects pose a significant public health problem. One in 33 babies is born with a structural birth defect in the United States. Birth defects are a leading cause of infant mortality and responsible for considerable morbidity with enormous economic and social costs. Symptoms appear at birth or very soon afterwards. How bad the symptoms are depends on whether there is a way for the two separate blood circuits to mix, allowing some oxygen-rich blood to get out to the body. This mixing can occur through other defects, such as a hole between the bottom chambers of the heart (a ventricular septal defect), or through a shunt that normally is present at birth. Symptoms also can depend on whether other defects are present as well. Common symptoms of TGA include: -Blueness of the skin -Shortness of breath -Poor feeding Surgery might be needed shortly after birth. In most hospitals, a type of surgery called an arterial switch procedure can be used to permanently correct the problem within the first week of life. Without corrective surgery, severe cases of TGA can be fatal during the first 6 months of life.

How Do We Compare With the U.S.?

The national prevalence transposition of the great arteries among births from 2004-2006 is 3.00 per 10,000 births.These data come from 14 birth defects surveillance programs: Arkansas, Arizona, California [8-county Central Valley], Colorado, Georgia [5-county metropolitan Atlanta], Illinois, Iowa, Kentucky, Massachusetts, North Carolina, Oklahoma, Puerto Rico, Texas, and Utah.

Data Notes

New Mexico live-born infants with transposition of the great arteries (TGA), 2006-2011. The following International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes were used to identify TGA: 745.10, 745.11 (includes only double-outlet right ventricle, TGA type), 745.19. In 1987, CDC put forth a set of 6 digit codes (the sixth digit provides greater specificity for diagnosis) based on the British Pediatric Association Classification of Diseases and the ICD-9-CM. If CDC/BPA codes are present, the following were used to identify TGA: 745.100 - 745.190.
