FAQ
A healthcare provider may recommend a PFO closure procedure if: You've had a transient ischemic attack (TIA) more than once. You've had cryptogenic (from an unknown cause) strokes more than once. You have a low level of oxygen in your blood.
The opening is supposed to close soon after birth, but sometimes it does not. In about 1 out of 4 people, the opening never closes. If it does not close, it is called a PFO. The cause of a PFO is unknown.
Are You a Candidate for PFO Closure? You may be a candidate for minimally invasive PFO closure if you: Have been diagnosed with a PFO and have had a stroke due to an unknown cause (one not attributed to a condition such as atrial fibrillation or carotid artery disease)
PFO closure may be offered to younger patients (e.g., <30 years) with a single, small, deep stroke (<1.5 cm), a large shunt, and absence of any vascular risk factors that would lead to intrinsic small-vessel disease such as hypertension, diabetes, or hyperlipidemia (level C).
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 .
For small PFOs without associated interatrial septal aneurysm, the 25-mm size Cribriform, PFO occluder, or Helex is preferred. Using devices smaller than 25 mm in adults is not required and may increase the risk for device embolization.
If it does not close, it is called a PFO. The cause of a PFO is unknown. There are no known risk factors. It can be found along with other heart abnormalities such as atrial septal aneurysms or Chiari network.

In this heart surgery, the surgeon uses stitches to close the PFO . Patent foramen ovale closure is a procedure to close a hole in the heart.We use minimally invasive approaches to treat PFO without open-chest surgery. A patent foramen ovale (PFO) is a hole in the heart that didn't close the way it should after birth. The foramen ovale is a hole in the wall between the left and right atria of every human fetus. This hole allows blood to bypass the fetal lungs. This document addresses the transcatheter closure of patent foramen ovale and transcatheter or open left atrial appendage (LAA) closure. A patent foramen ovale occurs when a hole that is always present in a newborn's heart fails to close as it should once the lungs begin to function after birth. Percutaneous closure of a patent foramen ovale (PFO) reduces the risk of recurrent cryptogenic stroke specifically in younger patients. Patent foramen ovale (PFO) is a common congenital heart defect that can lead to significant complications.
