Patent Foramen Ovale/Atrial Septal Defect (PFO/ASD) Closure

This procedure is done to close a small hole that is in the inside wall of the heart between the left and right chambers. A catheter, similar to an IV, is inserted into your groin and follows the path that leads to your heart. When the catheter reaches the inside of your heart wall where the hole is, a tiny umbrella-like device is released through the catheter. It is positioned so that it plugs the hole between the left and right sides of your heart. The device is secured in place and the catheter is then withdrawn from the body.
