Most cases of PDA are diagnosed and treated soon after birth. If it does, however, it can cause several health problems. The larger the opening is, the worse the complications. However rare, untreated adult PDA can lead to other medical conditions in adults, such as:. In very serious cases of untreated adult PDA, extra blood flow can eventually increase the size of the heart, weakening the muscle and its ability to pump blood effectively.
This can lead to congestive heart failure and death. The outlook is very good when PDA is detected and treated. Recovery for premature babies will depend on how early the baby was born and whether or not other illnesses are present. Most infants will make a complete recovery without experiencing any PDA-related complications. Dextrocardia is a rare heart condition in which your heart points toward the right side of your chest instead of the left side.

Caudal regression syndrome, or sacral agenesis, is a rare condition where the lower spine doesn't fully form before birth. Here's what you should know. Mermaid syndrome is a severe and often fatal congenital abnormality involving fused limbs, which have been described as resembling a mermaid's tail. According to an observational study in , couples, there was a 35 percent increase in the chance of birth defects in newborns if the father….
Krabbe disease is a rare and life threatening disorder of the nervous system. Sturge-Weber syndrome is a rare neurological disorder present at birth. After the first few weeks of life, medicine won't work as well to close the ductus and surgery may be required. If the PDA is small, or if it has been closed with catheterization or surgery, your child may not need any special precautions regarding physical activity and may be able to participate in normal activities without increased risk.
As far as follow up in the future, depending on the type of PDA closure, your child's pediatric cardiologist may examine it periodically to look for uncommon problems. The long-term outlook is excellent, and usually no medicines and no additional surgery or catheterization are needed. Congenital Heart Defect ID sheet. After birth, the opening is no longer needed and it usually narrows and closes within the first few days of life.
Sometimes the ductus doesn't close after birth. Failure of the ductus to close is common in premature infants but rare in full-term babies, and the cause is usually not known.
Some patients can have other heart defects along with the PDA. In a person with PDA, extra blood gets pumped from the body artery aorta into the lung pulmonary arteries. If the PDA is small, it won't cause symptoms or problems because the blood flow and pressure in the heart and lungs aren't changed appreciably from normal.
The only abnormal finding may be a distinctive type of murmur noise heard with a stethoscope , sometimes called a "machinery" murmur. If the PDA is large, breathlessness may be due to reduced heart function or problems related to high pressures in the lungs. High pressure may occur in the lung vessels because more blood than normal is being pumped there.
Over time this may cause permanent damage to the lung blood vessels pulmonary hypertension. If the PDA is small, it doesn't have to be closed because it doesn't make the heart and lungs work harder.
Patients with a moderate- or large-sized PDA may develop problems related to the increased blood flow to the lungs. These patients may have improvement if the PDA is closed. Closing the PDA can now usually be performed by catheter coil placement or other device insertion to plug the abnormal communication referred to as interventional or therapeutic catheterization PDF.
Surgery may be the best treatment option for some patients. The surgeon doesn't have to open the heart to fix the PDA. An incision is made in the left side of the chest, between the ribs. The PDA is closed by tying it with suture thread-like material or by permanently placing a small metal clip around the PDA to squeeze it closed. Occasionally in the adult, a surgical patch is used. If there's no other heart defect, this restores the circulation to normal. Genetic factors might play a role.
Before birth, an opening that connects two major blood vessels leading from the heart — the aorta and pulmonary artery — is necessary for a baby's blood circulation. The connection diverts blood from a baby's lungs while they develop, and the baby receives oxygen from the mother's circulation. 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. Untreated, the blood pressure in the baby's lungs might increase pulmonary hypertension and the baby's heart might enlarge and weaken.
A small patent ductus arteriosus might not cause complications. Larger, untreated defects could cause:. Most women who have a small patent ductus arteriosus can tolerate pregnancy without problems. However, having a larger defect or complications — such as heart failure, arrhythmias or pulmonary hypertension — can increase the risk of complications during pregnancy. If you have Eisenmenger syndrome, pregnancy should be avoided as it can be life-threatening.
If you have a heart defect, repaired or not, discuss family planning with your doctor. In some cases, preconception consultations with doctors who specialize in congenital cardiology, genetics and high-risk obstetric care are needed. Some heart medications can cause serious problems for a developing baby, and it might be necessary to stop or adjust the medications before you become pregnant.
There's no sure way to prevent having a baby with a patent ductus arteriosus. However, it's important to do everything possible to have a healthy pregnancy.
Here are some of the basics:. The coils obstruct blood flow through the vessel, in part by stimulating the development of a blood clot at the site. This procedure achieves an excellent result in most patients. Complications are rare and include bleeding, infection, and early dislodgment of the coil.
If the coil dislodges it can usually be retrieved at the time of the procedure and repositioned or replaced with a larger size coil. The procedure is done as an outpatient and children can resume all activities within 48 hours. Surgical closure of patent ductus arteriosus: Surgical results are also excellent. It is done through a small incision between the ribs on the left side. The ductus is identified and either tied off or divided. Surgical complications are rare and include hoarseness or paralyzed diaphragm, infection, bleeding, and accumulation of fluid around the lungs.
Most children go home two or three days after the surgery. The outlook for these patients is excellent as long as treatment is initiated soon enough to prevent pulmonary vascular obstructive disease.
Possible long-term complications include coarctation narrowing of the aorta or recurrence of the vessel although both problems are extremely rare. Transcatheter occlusion of patent ductus arteriosus.
