PATENT FORAMEN OVALE CLOSURE (PFO) printer-friendly PDF version

What is it?
CardioSeal Closure is used to close Patent Foramen Ovale (a hole in the heart).

What will happen? Cardioseal Closure is performed by a doctor, using catheters, in the heart catheterization laboratory. The doctor will gain access to your heart using a major vein in the groin. Various catheters will be advanced from the groin into the heart. A test involving moving pictures of the heart, called an angiogram, may be taken to better visualize the heart and the hole. The doctor may also use a special ultrasound procedure, called echocardiography (echo) to better see the heart and the hole. One type of echo involves putting a tube into the esophagus. Another type uses a vein to place the echo tube inside the heart. These tests are used to decide which size CardioSeal will be used to close the hole.

What do I do?
  • Do not smoke 24 hours prior to the procedure
  • Do not eat or drink anything after midnight the night before the test.
  • Consult with us regarding which medications to continue to take the evening before the test.
  • If you are a diabetic, have renal insufficiency, or a potential iodine dye allergy, please notify this office at (713) 790-9401.

  • Dizziness

Let the staff know immediately if you experience any symptoms after the procedure such as:
  • Bleeding or wetness at the cath site
  • Pain or numbness
  • A knot at the site larger than a small marble
How long does it take?
