Several genetic health conditions that a baby inherits from 1 or both parents can cause congenital heart disease. It’s also recognised that certain types of congenital heart disease run in families. Down’s syndrome is the most widely-known genetic condition that can cause congenital heart disease.
However, when it comes to more serious concerns, such as heart disease, we tend to assume that lifestyle habits are the cause. And while this is sometimes the case, there are other times when it may be genetic, passed down from parents to children. Certain heart diseases can be passed down genetically.
The exact cause of most heart defects isn’t known. Although it’s presumed to be genetic, only a few genes have been linked to heart defects. That means heart defects are likely due to a combination of multiple genetic and environmental factors. There’s usually a 2 to 15 percent chance of a heart defect recurring in a family.
Genetic syndrome. Some people with congenital heart defects have a specific genetic condition that can include other health problems. They may or may not be aware that they have such a condition. The chances that people with this genetic condition will pass it along to their child can be as high as 50 percent.
Is heart disease inherited from mother or father?
Most genetic heart conditions are inherited in an autosomal dominant pattern. Autosomal means that both men and women are equally affected. Dominant means that although there are two copies of each gene, a mutation in just one copy is enough to cause disease.
What is the most common inherited heart defect?
Some babies have heart defects because of changes in their individual genes or chromosomes. CHDs also are thought to be caused by a combination of genes and other factors, such as things in the environment, the mother’s diet, the mother’s health conditions, or the mother’s medication use during pregnancy.
How can I prevent my baby from having a heart defect?
Take 400 micrograms of folic acid supplement a day during the first trimester (first 12 weeks) of your pregnancy – this lowers your risk of giving birth to a child with congenital heart disease, as well as several other types of birth defect.
What are some of the signs a baby may have a heart defect?
Approximatelyone in every 100 babies is born with a heart defect. This is called a congenital heart defect (CHD). Some defects are mild and cause no significant disturbance to the way the heart functions. However, more than half of all children with CHD have a condition that is serious enough to require treatment.
How common is it for a baby to be born with a heart defect?
The most common type of heart defect is a ventricular septal defect (VSD).
Should I be concerned if my baby’s ultrasound shows a heart defect?
The results can offer reassurance to worried parents or detect a genetic syndrome that may help parents prepare for life after the baby is born. “The outcome for a child with a heart defect is typically better if there’s no associated genetic syndrome and the chromosomes are normal,” Dr. Chao says.
What heart problems can a fetus have?
More important fetal heart problems include tachycardia (hear rate too fast) and bradycardia (heart rate too slow). Some fetuses with tachycardia require medication (given to the mother); in extreme cases this can affect the well being of the fetus.
How common are heart defects in fetuses?
Without treatment, critical CHDs can cause serious health problems and death. Nearly 1 in 100 babies (about 1 percent or 40,000 babies) is born with a heart defect in the United States each year. About 1 in 4 babies born with a heart defect (about 25 percent) has a critical CHD.
Can ultrasound detect heart defects?
Echocardiography is a type of ultrasound scan, where high-frequency sound waves are used to create an image of the heart. However, it’s not always possible to detect heart defects, particularly mild ones, using foetal echocardiography.
How common are defects at 20-week scan?
The scan will find about half (5 out of 10) of babies who have heart defects. Some of the conditions that can be seen on the scan, such as cleft lip, will mean the baby may need treatment or surgery after they’re born.
What causes fetal heart abnormalities?
In around eight out of 10 cases, the reason for the congenital heart defect is unknown. Some of the known causes of CHD include: Genes – 20 per cent of cases have a genetic cause. Other birth defects – a baby affected by certain birth defects, such as Down syndrome, is more likely to have malformations of the heart.
How do you know if your fetus has a heart defect?
Congenital heart disease may initially be suspected during a routine ultrasound scan of the baby in the womb. Specialist ultrasound, called foetal echocardiography, will then be carried out at around 18 to 22 weeks of the pregnancy to try to confirm the exact diagnosis.
