Patent Ductus Arteriosus (PDA) is a congenital heart condition in which a blood vessel connecting the aorta and pulmonary artery fails to close after birth. As a result, oxygen-rich blood flows abnormally into the lungs, causing increased lung blood flow and overload of the left side of the heart.
PDA device closure is a safe, catheter-based procedure that seals the abnormal connection without open-heart surgery and allows rapid recovery.
PDAs vary in size and shape. They may be small and silent or large with significant left-to-right shunt. Angiographic classification includes tubular and elongated PDAs as well as Krichenko types A to E.
- Small / Silent PDA
- Moderate PDA
- Large PDA causing increased lung blood flow
- Tubular and elongated PDAs
- Krichenko angiographic types A–E
- Left heart enlargement on echocardiography
Who Needs PDA Closure?
PDA closure is recommended in patients who develop symptoms or complications due to persistent abnormal blood flow between the aorta and pulmonary artery.
Indications include failure to thrive in infants, frequent pneumonia or respiratory infections, continuous heart murmur, left heart enlargement, large PDA with increased lung blood flow, and prevention of endocarditis.
The procedure is performed under local or general anesthesia. A catheter is inserted through the femoral vein or artery, the PDA is crossed using a guidewire, and a coil or occluder device is deployed to completely seal the PDA.
The procedure usually takes 30 to 60 minutes, depending on the size and anatomy of the PDA.
Most patients are discharged the same day or after one day of observation.
PDA closure avoids open surgery, has a very high success rate, leaves no scar, allows quick recovery, and enables return to normal activity within days.
