Can rubella cause congenital heart disease?
Severe rubella virus infection, acquired in utero early in pregnancy, is named as Congenital Rubella Syndrome (CRS). It refers to variable constellations of birth defects (for example, hearing impairment, congenital heart defects, cataracts or congenital glaucoma, pigmentary retinopathy, etc).
What heart defect is associated with rubella?
The cardiac abnormality most frequently found in rubella syndrome is a combination of branch pulmonary artery stenosis and patent ductus arteriosus, though isolated branch pulmonary artery stenosis is twice as common as isolated patent ductus arteriosus [1].
What is the most common congenital defect of congenital rubella syndrome?
[1–3] Common congenital defects of CRS include cataracts, congenital heart disease, hearing impairment, and developmental delay. Infants with CRS often present with more than one of these signs but may also present with a single defect, most commonly hearing impairment.
What maternal disease can cause congenital heart disease?
It isn’t usually a serious infection for adults or children, but it can severely affect an unborn baby if a mother develops a rubella infection during the first 8 to 10 weeks of pregnancy. A rubella infection can cause multiple birth defects, including congenital heart disease.
How does rubella cause birth defects?
If a pregnant woman is infected with rubella, she can pass the virus to her baby, which can lead to a miscarriage or an infant born with the congenital rubella syndrome (CRS). CRS can cause severe birth defects such as heart problems, loss of hearing and eyesight, intellectual disability, and liver or spleen damage.
What are the risks to the baby if a woman catches rubella during the first trimester?
Rubella can be serious for the baby, especially during the first 3 months. Having rubella during pregnancy increases the risk of: Congenital rubella syndrome (CRS) – This is a condition that happens when a pregnant person passes rubella to their baby during pregnancy.
When is a pregnant woman at risk for developing congenital rubella syndrome?
A fetus infected early in the pregnancy (especially during the first trimester) has a high probability of developing CRS. In symptomatic women infected with rubella during the first 12 weeks (first trimester) of pregnancy, CRS-associated congenital defects occur in up to 85% of infants.
What are the long term side effects of rubella?
Complications
- heart problems,
- loss of hearing and eyesight,
- intellectual disability, and.
- liver or spleen damage.
What are some signs of congenital rubella syndrome?
Deafness, eye abnormalities, and congenital heart defects are the most common symptoms of CRS. Neurologic abnormalities, such as a reduced head size (microcephaly) and mental retardation, and other abnormalities, including spleen, liver or bone marrow problems, and low birth weight may also occur.
What are the top 3 congenital heart diseases?
Here are eight of the most common types of congenital heart defects:
- Ventricular septal defect.
- Treatment.
- [See: Best Children’s Hospital National Rankings.]

What are the 5 main types of congenital heart disease?
Congenital heart disease refers to a range of possible heart defects.
- Aortic valve stenosis. Aortic valve stenosis is a serious type of congenital heart defect.
- Coarctation of the aorta.
- Ebstein’s anomaly.
- Patent ductus arteriosus.
- Pulmonary valve stenosis.
- Septal defects.
- Single ventricle defects.
- Tetralogy of Fallot.
How does rubella affect an unborn baby?
Rubella caught in the first ten weeks of pregnancy causes damage to nine out of ten unborn babies. The mother passes the virus on to her unborn baby and it damages the organs as they develop, particularly the developing eyes, ears, heart and brain – often in combination.
What happens if rubella IgG is positive during pregnancy?
Background: Infection of mothers with Rubella virus during pregnancy can be serious; if the mother is infected within the first 20 weeks of pregnancy she is likely to have miscarriage, stillbirth, or baby with congenital rubella syndrome.
How does rubella cause fetal abnormalities?
Intracellular actin assembly is inhibited by rubella infection, leading to inhibition of mitosis and restricted development of precursor cells. Upregulation of cytokines and interferon in infected cells which could contribute to congenital defects.
What is the most serious complication of rubella?
Up to 70% of women who get rubella may experience arthritis; this is rare in children and men. In rare cases, rubella can cause serious problems, including brain infections and bleeding problems. liver or spleen damage.
What organs does rubella affect?
Babies born with congenital rubella syndrome are at risk for serious problems with their growth, thinking, heart and eyes, hearing, and liver, spleen, and bone marrow.
What is the commonest congenital heart disease in pregnancy?
The most common congenital heart diseases in pregnant women, which account for nearly 60% of cases, are patent ductus arteriosus, atrial septal defect and ventricular septal defect.
What is the most common congenital heart defect in babies?
The most common type of heart defect is a ventricular septal defect (VSD).
What is the most serious congenital heart defect?
Critical congenital heart defects (also called critical CHDs or critical congenital heart disease) are the most serious congenital heart defects.
What are the complications of rubella?
Complications include deafness, cataracts, heart defects, brain disorders, mental retardation, bone alterations, liver and spleen damage. Furthermore, an infant infected with rubella during pregnancy can continue to shed the virus for about a year, sometimes longer.
What happens if rubella IgG is very high?
A positive test is 1.0 or higher. That means you have rubella antibodies in your blood and are immune to future infection. A negative test is 0.7 or lower. You have too few antibodies to make you immune.
What happens if my rubella IgG is high?
Positive: A positive rubella IgG test result is good—it means that you are immune to rubella and cannot get the infection. This is the most common rubella test done.
What are the 4 types of congenital heart defects?
Ebstein anomaly. hypoplastic left heart syndrome. patent ductus arteriosus (PDA) patent foramen ovale (PFO)
What happens if rubella IgG is high in pregnancy?
Pregnant women who contract rubella are at risk for miscarriage or stillbirth, and their developing babies are at risk for severe birth defects with devastating, lifelong consequences. CRS can affect almost everything in the developing baby’s body. The most common birth defects from CRS can include: Deafness.
What is the normal range of rubella IgG in pregnancy?
Results: Quantitative analysis of the IgG levels showed noticeable variability that ranged between 24-143 IU/ml (average 94). One hundred and forty-five (91%) out of 160 women had rubella IgG levels of above 50 IU/ml with a range of 54-143 IU/ml (average 92) while 15 (9%) had a level between 24-46 IU/ml (average 38).
