Prevalence of Transposition of the Great Arteries by County, New Mexico, 2015-2019
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; and 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.
Definition
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). New Mexico live-born infants with transposition of the great arteries (TGA), 2015-2019.

How the Measure is Calculated
| Numerator: | Number of live-born infants with transposition of the great arteries. |
| Denominator: | Number of live-born infants. |
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.

What Is Being Done?
All birthing facilities in New Mexico are required to screen newborns for risk of heart defects, including congenital heart defects (CHDs), such as transposition of the great arteries.* The screen for CHDs, called pulse oximetry, is painless and measures the baby's pulse and the level of oxygen in the baby's blood. Screening performed in the birthing facility before discharge allows immediate referral for follow-up testing. Pulse oximetry alone cannot diagnose a heart defect. *Parents choosing to forego this screening must sign a waiver.
