A left-to-right shunt is a heart defect that allows oxygen-rich blood to move from the left side of the heart to the right side.
- It causes too much blood flow to the lungs.
- This makes the lungs work harder and makes it hard for the baby to breathe.
Blood low in oxygen is pumped from the
heart to the lungs. Blood high in oxygen is
returned from the lungs to the heart and
pumped to the rest of the body.
Then, talk to your pediatrician about the results.
Your baby's heart and lungs have to work together, so CHD can also create lung problems. When there is a hole in the baby’s heart, this causes blood to flow in an incorrect pattern in a process called shunting:
Babies with CHD have an increased risk for severe RSV disease, especially while 24 months of age or younger at the start of the RSV season, and are 2 to 3 times more likely than lower-risk babies to be hospitalized for severe RSV infection.
Synagis is a prescription medication that is used to help prevent a serious lung disease caused by respiratory syncytial virus (RSV) in children at high risk for severe lung disease from RSV.
Children should not receive Synagis if they have ever had a severe allergic reaction to it. Signs and symptoms of a severe allergic reaction could include itchy rash; swelling of the face; difficulty swallowing; difficulty breathing; bluish color of the skin; muscle weakness or floppiness; a drop in blood pressure; and/or unresponsiveness. If your child has any of these signs or symptoms of a severe allergic reaction after getting Synagis, be sure to tell your child’s healthcare provider or get medical help right away.
Synagis is given as a shot, usually in the thigh muscle, each month during the RSV season. Your child should receive their first Synagis shot before the RSV season starts, to help protect them before RSV becomes active. When RSV is most active, your child will need to receive Synagis shots every 28-30 days to help protect them from severe RSV disease for about a month. Your child should continue to receive monthly shots of Synagis until the end of RSV season. Your child may still get severe RSV disease after receiving Synagis. If your child has an RSV infection, they should continue to get their monthly shots throughout the RSV season to help prevent severe disease from new RSV infections.
The effectiveness of Synagis shots given less than monthly throughout the RSV season has not been established.
Possible, serious side effects include severe allergic reaction, which may occur after any dose of Synagis. Such reactions may be life-threatening or cause death. Unusual bruising and/or groups of tiny red spots on the skin have also been reported.
Common side effects of Synagis include fever and rash. Other possible side effects include skin reactions around the area where the shot was given (like redness, swelling, warmth, or discomfort).
