PFO & ASD Closure is a procedure to repair a small opening in the wall between the upper chambers of the heart. Two types of openings wall are Patent Foramen Ovale (PFO) and Atrial Septal Defect (ASD).
Procedure of PFO & ASD closure
The techniques for PFO and ASD closure are almost equal; PFO & ASD Closure procedure is performed using X-rays and echo ultrasound guidance, usually under a general anesthetic.
Electrodes (small, sticky patches) will be placed on your chest. These are attached to a monitor to measure your heart’s electrical activity. Your heart will also be monitored with an echocardiogram (heart ultrasound), sometimes by passing a probe down your esophagus, or from your blood vessel into your heart.
A fine tube, a catheter, is passed from the blood vessel at the top of the leg to the heart, where it is guided across the PFO or ASD. A device, of which there are now many types, is carefully positioned to straddle the hole, and it is then deployed across the PFO/ASD. This will immediately diminish the potential for blood to shunt across the hole, and over time the body forms a thin lining over the device, reducing the shunt even further and generally sealing it completely.
Patients can expect to go home either the evening of the procedure or the following day and is usually prescribed aspirin and similar drugs for a few months afterwards. You may feel sore from several hours of lying flat but this will go away in a day or so. The catheter site will be bruised, but this should go away in about a week. You might also temporarily have a sore throat if a tube was placed down your throat to take ultrasound images of your heart.
Patients can lead an entirely normal life after the procedure but should have intermittent reviews for life to check that all remains well.
There are risks with any kind of procedure, including ASD or PFO closure. But serious complications are rare. Risks include:
Temporary leg numbness or weakness in the first few hours afterward (rare) Bruising, bleeding, infection, or blood vessel damage where catheter(s) were inserted
Damage to the heart muscle that may require open heart surgery
Abnormal heart rhythm
Heart attack or stroke
Negative reaction to anesthetic or dye
