THE “HOLE” TRUTH ABOUT CRYPTOGENIC STROKE
Before birth, a baby’s heart will have a hole with a flap-like covering between the upper two chambers of the heart. This opening (the foramen ovale) allows blood rich in oxygen from the mother to bypass the baby’s lungs which do not function until the baby is born. After birth, the flap-like covering will typically close the hole permanently. However, in about one out of every four individuals, the hole in the heart will remain open. This is called a patent foramen ovale or PFO.
From time to time, a PFO may permit blood to pass from the right side of the heart to the left side of
the heart bypassing the normal route of going through the lungs first. In most people, a PFO creates no symptoms and requires no treatment. However, in a small minority, a PFO may permit blood clots to pass from the right side of the heart to the left side possibly leading to a stroke.
A medical team, including a neurologist and a cardiologist, will conduct tests to look for the cause of your stroke. These tests include collecting images of your brain, heart, and blood vessels (using ultrasound, CT and / or magnetic resonance imaging [MRI] scans), monitoring your heart rhythm, and blood tests. If your doctors do not find any likely cause of your stroke from this testing, they may conclude that you had a cryptogenic stroke.
A PFO is found by a cardiologist using ultrasound pictures of the heart (echocardiogram or echo). The ultrasound uses sound waves to evaluate the structure of the heart and the direction of blood flow to see if blood can pass from the right side of the heart to the left side.
If no other identifiable cause of the stroke can be found, your doctors may conclude that the PFO played an important role by permitting a blood clot to pass from the right side of your heart to the left side and blocking a blood vessel that supplies the brain.
The GORE® CARDIOFORM Septal Occluder is a minimally invasive device intended for the closure of a PFO using cardiac catheterization. It is a permanent implant consisting of a near circular wire frame covered with thin ePTFE material. The soft, conformable ePTFE material, invented and manufactured by Gore, has been used in open-heart surgery for more than 40 years and has been shown to be safe in implanted medical devices. The wire frame is made of a nickel-titanium metal alloy called nitinol with a platinum core (so that it may be seen on X-ray images).
The Gore REDUCE Clinical study demonstrated a 77% relative stroke reduction with PFO closure plus medical therapy vs. medical therapy alone*,4
The Gore REDUCE Clinical Study is the only U.S. IDE trial that achieved its primary end point and showed the largest reduction in recurrent ischemic stroke *,4 in all PFO shunt sizes over medical therapy alone.
Ask your doctor if Gore GORE® CARDIOFORM Septal Occluder is right for you.
