Pediatric Cardiology >
Patent Ductus Arteriosus
The pulmonary artery supplies blood to the lungs while the aorta supplies blood to the body. The ductus arteriosus is a normal structure in a baby's heart that normally closes shortly after birth.
If the ductus arteriosus stays open, or "patent," the heart must work harder and more blood goes to the lungs and they may become congested.
With this condition, children may tire quickly, catch pneumonia easily and breathe rapidly. Marshfield Clinic has full time pediatric cardiologists available to diagnose and treat patients with PDA.
A PDA may close on its own, without treatment. If it doesn't, treatment options include cardiac catheterization or surgery.
Cardiac catheterizationCardiac catheterization is done on the heart using a thin, flexible tube called a catheter. The catheter is inserted into a blood vessel in the groin. With the help of live x-rays, the catheter is advanced up through the blood vessel until it reaches the heart.
A coil or a closing device is used to close the PDA, and when the coil or closing device is delivered and placed in the PDA, the catheter is removed leaving the closing device in place.
If this is a medical emergency, call 911.
