Complete Indicator Profile of Birth Defects: Congenital Heart Defects

Definition

Number of cases of major heart defects per 1,000 births.

Numerator

Number of cases of major heart defects among live births and fetal deaths occurring among women residing in Utah. This number excludes mild or minor conditions such as isolated patent foramen ovale, patent ductus arteriosus, and muscular ventricular septal defect. Diagnoses are confirmed by echocardiography, catheterization, surgery, or autopsy.

Denominator

Number of live births and stillbirths among women residing in Utah.

Why Is This Important?

Congenital heart defects are among the most common birth defects. Many affected children require medical and surgical treatment. Even after treatment, some children may be at increased risk of illness and death because of cardiovascular complications, rhythm abnormalities, or other long-term adverse events.

As treatment and support continually improves, increasing number of affected people live longer and healthier lives. Adolescents and adults that have been successfully treated now represent a growing group in the population and have specific health care needs.

Tracking congenital heart defects in Utah is crucial in assessing the impact of these common conditions, evaluating its causes, and helping to plan appropriately for the care of affected children and adults.

Burden of disease and medical costs associated with congenital heart defects are substantial. $1.2 billion is the estimated lifetime cost for U.S. children born in a single year with one of four major heart defects (tetralogy of Fallot, transposition of the great arteries, single ventricle, truncus arteriosus) (Waitzman and collaborators, 1994).

How Are We Doing?

The Utah Birth Defect Network began tracking selected congenital heart defects (conotruncal and left obstructive heart defects) in 1997 and later expanded to include all major heart defects. This report is based on 1,418 affected births reported to the Network from 1997 through 2003.

The Network reports that the overall rate of major congenital heart defects in 2003 in Utah was 0.6% (6.3 per 1,000), or 1 in 159 births. On average, approximately 300 affected babies or more are born every year in Utah.

Overall rates of major heart defects for birth year 2003 are similar in different racial and ethnic groups. Some rates are based on small numbers of affected babies and thus their confidence intervals are wide. For some groups such as Native Americans and African Americans the number of affected babies in 2003 were small (<10) and because the corresponding rates are statistically very unstable and not meaningful they are not reported.

How Do We Compare With U.S.?

Comparing rates among different areas requires caution as many aspects of the tracking programs in these areas can impact the reported rates. This is true generally for birth defects and particularly for heart defects, that require special examinations for diagnosis (e.g., echocardiography) and that often are suspected or diagnosed well after the newborn period. Thus programs with varying access to pediatric cardiology data and with different follow up periods can vary in their ability to detect and register affected babies and can therefore generate apparently different rates of heart defects.

Moreover, the reported overall rate of heart defect also depends on inclusion criteria. Because many minor or mild conditions (e.g., muscular ventricular septal defects, patent ductus arteriosus, patent foramen ovale) are quite frequent and are variably included in different tracking programs, their inclusion or exclusion can lead to considerable variations in reported rates.

It is therefore sensible to compare overall and specific rates among programs with similar methods of ascertainment and reporting. Comparisons are likely to be more meaningful for the more specific and severe heart defects, whose ascertainment and reporting are less likely to vary by much.

The overall rate of major heart defects in Utah (6.3 per 1,000) is comparable to that observed in the well-known Baltimore Washington Infant Study, where the rate varied between 4 and 8 per 1,000 depending on time and inclusion criteria. The rate in Utah is lower than that reported in the Atlanta registry, managed by the Centers for Disease Control and Prevention, whose methods of ascertainment are similar to those in Utah Birth Defect Network. The lower rate in Utah is likely due to the use of more restrictive reporting criteria, such as the exclusion from rate computations of common mild heart conditions (see definition of numerator). For specific, severe heart defects such as tetralogy of Fallot, d-transposition of the great arteries, and hypoplastic left heart, observed rates in Utah are comparable to those observed in Metropolitan Atlanta and in the Baltimore Washington Infant Study.

What Is Being Done?

The Utah Birth Defect Network (UBDN) currently is tracking rates of congenital heart defects, evaluates their reported origin and time/space clustering, and, more recently, is involved in studies of causation with the goal of finding strategies for primary prevention.

Specific services for families of affected children from birth to three years of age are provided by the Utah Early Intervention Program, located within the Bureau of Children with Special Health Care Needs, Utah Department of Health. Services include child health assessment; service coordination among providers, programs, and agencies; occupational and physical therapy; and speech and language therapy. Information on these services is available at http://www.utahbabywatch.org

A further resource is the Utah Collaborative Medical Home, which is a project designed to provide information, tools, and resources for primary care physicians to enhance their ability to care for children with special health care needs. Information on the Utah Collaborative Medical Home is available at their web site: http://www.medhomeportal.org
