FAQ
If a PFO exists, tiny air bubbles will be seen moving from the right to left side of the heart.
How is patent foramen ovale treated? Most PFOs don't need any treatment. If your child needs surgery for another heart defect, the PFO may be closed at the time of the surgery. In rare cases, your child's doctor may recommend closing the PFO surgically.
Because of its valvelike nature, PFO does not shunt left to right, but in our series, 11% of patients were observed to have a bidirectional flow from the PFO conduit.
Examples of right-to-left cardiac shunts include: Double outlet right ventricle. Eisenmenger syndrome. Hypoplastic left heart syndrome (HLHS).
Exams and Tests If a PFO exists, tiny air bubbles will be seen moving from the right to left side of the heart.
The procedure involves making a small incision, typically in the groin, and inserting a small tube, called a catheter or sheath, to navigate through the blood vessels to the procedure site within the heart. In patients with a PFO, the doctor guides the closure device through the catheter or sheath to seal the PFO.
This new flow helps push the patent foramen ovale closed. The blood can no longer flow directly between the upper two heart chambers. Instead, it flows from the right side of the heart into the baby's lungs to pick up oxygen, and then the left side of the heart sends the oxygen-rich blood out to the body.
Procedures to close a patent foramen ovale include: Device closure. In this procedure, the provider inserts a thin, flexible tube called a catheter into a blood vessel in the groin area. The catheter tip has a device to plug the PFO . Surgical closure. In this heart surgery, the surgeon uses stitches to close the PFO .
For those patients who need or want to avoid PFO, the panel judged anticoagulation the best alternative, although the evidence regarding stroke reduction was of low certainty. The risk of major bleeding probably increased with anticoagulation.
How is patent foramen ovale treated? Antiplatelet medicines such as aspirin, to help prevent blood clots. Anticoagulant medicines such as warfarin, to help prevent blood clots. Closure of the PFO with a catheter-based procedure. Closure of the PFO during heart surgery.
