What's the treatment for PDA?

The premature neonate with a significant patent ductus arteriosus (PDA) is usually treated with intravenous (IV) indomethacin or ibuprofen. This has been quite successful in most patients.

How does ibuprofen close a PDA?

Ibuprofen's mechanism of action for closure of PDA is believed to be through the inhibition of prostaglandins. Clinical studies have shown ibuprofen to be as effective as indomethacin with fewer adverse effects. The ductus arteriosus is a blood vessel that connects the pulmonary artery to the aorta.

Is PDA hereditary?

The cause of PDA is not known, but genetics might play a role. PDA is more common in premature babies and affects twice as many girls as boys.

What is the cause of PDA?

Key points about PDA PDA is a heart defect found in the days or weeks after birth. It occurs because a normal fetal connection between the aorta and the pulmonary artery does not close as it should after birth. PDA happens most often in premature infants. It often occurs with other congenital heart defects.

Is PDA life threatening?

It is important to correct PDA because it can lead to congestive heart failure and a disease of the right side of the heart (called cor pulmonale) later in life. PDA also increases the risk of endocarditis, a life-threatening infection of the lining that covers the heart chambers, valves, and main arteries.

What are the symptoms of PDA?

Symptoms

• Poor eating, which leads to poor growth.
• Sweating with crying or eating.
• Persistent fast breathing or breathlessness.
• Easy tiring.
• Rapid heart rate.

How long does a PDA take to close?

After birth, the ductus arteriosus normally closes within two or three days. In premature infants, the opening often takes longer to close. If the connection remains open, it's referred to as a patent ductus arteriosus. The abnormal opening causes too much blood to flow to the baby's lungs and heart.

What drug is used to keep PDA open?

Medicines. Indomethacin (in doh METH ah sin) is a medicine that helps to close a PDA in premature infants because it causes the PDA to tighten up (constrict) which closes the opening.

What are the signs of PDA?

Young people with PDA are more likely to:

• resist demands obsessively (100%)
• be socially manipulative (100% by age of 5)
• show normal eye contact.
• show excessive lability of mood and impulsivity.
• show social mimicry (including gesture)
• show role play (more extended and complete than mimicry)

Is PDA serious?

A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications.

How is the patent ductus arteriosus ( PDA ) treated?

• The ductus arteriosus supplies blood to the body from the pulmonary artery. Medicine is given, and the baby is watched closely in the intensive care unit. Keeping the patent ductus arteriosus open using this medicine allows time for the newborn to become stable until other treatments, usually surgery, are done.

Are there any medications that can close a PDA?

• Medications. In a premature baby, nonsteroidal anti-inflammatory drugs (NSAIDs) — such as ibuprofen (Advil, Infant's Motrin, others) or indomethacin (Indocin) — might be used to help close a PDA. NSAIDs block the hormonelike chemicals in the body that keep the PDA open. NSAIDs won't close a PDA in full-term babies, children or adults.

Is it important to have follow up care for PDA?

• If you have PDA, even if you had surgery as a child, you may be at risk of developing complications as an adult. So it's important to have lifelong follow-up care, especially if you had corrective heart surgery.

What happens to your heart if you have PDA?

• Heart failure. A PDA could cause a weak and enlarged heart and lead to heart failure, a condition that prevents the heart from pumping like it should. Heart infection (endocarditis). Your child may also be more likely to get an infection in the lining of their heart called endocarditis, but this is rare.
