Patent Ductus Arteriosus Device Closure. Dr Mustafa Bilge Erdogan. ISU Liv Hospital Bahcesehir

Closure of patent ductus arteriosus (PDA) using a device!

Patent ductus arteriosus (PDA) is a condition in which the ductus arteriosus, a vessel connecting the aorta and the pulmonary artery, remains open after birth. Normally, this ductus closes within the first few days of a child's life. However, if it remains open, it can lead to various complications such as heart failure and pulmonary hypertension.

Closing the defect helps eliminate symptoms such as shortness of breath, fatigue, and rapid heartbeat. It reduces the risk of serious complications such as heart failure and pulmonary hypertension. Timely closure of PDA can extend the patient's life, preventing the progression of the disease.

Devices for closing the arterial duct!

Modern medical technologies offer several types of devices used to close PDA. Here are some of them

1. Occluders

• Amplatzer Duct Occluder: This is one of the most commonly used devices for closing PDA. It consists of a nitinol mesh that self-expands after placement in the ductus. The device has two disc-shaped parts that are fixed on either side of the ductus, ensuring reliable closure
• Gianturco Coils: These spiral devices are used to close small PDAs. They are made of platinum or steel and are inserted through a catheter. The coils curl up inside the ductus, blocking blood flow

2. Catheter systems

• Balloon catheter systems: These systems are used for temporary closure of PDA in critical situations, such as premature birth. A balloon is inserted through a catheter and inflated inside the ductus, blocking blood flow
• Occluder catheter systems: These systems include a catheter and an occluder, which is inserted through the catheter and placed in the ductus. The occluder self-expands and is fixed, ensuring permanent closure

3. Surgical clips

These devices are used in open surgical procedures to close PDA. Clips are fixed on the ductus, compressing it and blocking blood flow

4. Bioabsorbable devices

These devices are made from materials that dissolve over time in the body. They provide temporary closure of PDA until the tissue grows and closes the ductus naturally

Benefits of using devices for PDA closure

• Minimal invasiveness: Many devices are inserted through a catheter, avoiding open surgery and reducing recovery time
• Quick recovery: Patients usually return to normal life within a few days after the procedure
• Effectiveness: Modern devices provide reliable and long-lasting closure of PDA, improving the patient's quality of life
• Reduced risk of complications: Using devices reduces the risk of complications such as bleeding, infection, and damage to heart valves

How is the procedure performed?

The patient undergoes a preliminary examination, including echocardiography and angiography, to determine the size and location of the PDA. A catheter is inserted through the femoral vein and advanced to the heart under X-ray guidance. The occluder or another device is inserted through the catheter and placed in the ductus. The device self-expands and is fixed, ensuring closure of the PDA. The patient remains in the hospital under observation for a few days. Physical activity is restricted for some time. Regular follow-up visits are recommended to monitor the heart's condition.

Closure of PDA using devices is an important procedure to improve heart function and prevent potential complications associated with this congenital heart defect.
