A hole in your heart can be present in two forms. One is called PFO, or “patent foramen ovale,” a small opening between the two upper heart chambers. The other type is an ASD, or “atrial septal defect,” a congenital disability in which the hole is in the wall between the two upper heart chambers. These holes vary in size, and for some people, they close over time as a baby, while in others, the hole poses a health risk and must be closed.

What is a PFO?
A PFO is simply a hole between the two upper heart chambers. In some cases, the hole can lead to complications, including stroke. Before a baby is born, a natural hole exists between the two upper heart chambers, which usually closes before birth, and in some cases, a few days or even months after birth. If it does not close naturally, a hole is left, which for many people causes no problems – but in some cases, it is believed to lead to stroke, particularly if no other cause can be found. It may be necessary to close the hole, particularly if you have already suffered a stroke with an undetermined cause.
Stroke and PFO
A stroke comes about if the blood supply to the brain is dramatically reduced or blocked.
The brain, without the nourishment the blood provides, will begin to die, which often leads to disability or loss of life.
One type of stroke is called a “cryptogenic” stroke, which is a designation given to a stroke for which no medical cause can be found. Clinical studies have revealed that almost 50 percent of the people who suffer this type of stroke had a PFO – a hole between the two upper heart chambers.
Closing the PFO, at one time, required open-heart surgery. A more recently developed approach allows our heart specialists to close the hole with a minimally invasive procedure.
ASO Implantation: Close a Hole in the Heart – Without Open-Heart Surgery
An ASO is a catheter-based device that can be implanted to halt the blood flow between the two heart chambers. It is made of two discs that are linked together by a polyester thread to allow the device to collapse and fit through a narrow catheter. An access point is created in a blood vessel, and with real-time visual image guidance, is threaded through the vessel until it reaches the hole (PFO). Once in place, it is released and opens, plugging the hole. The procedure takes about one to two hours to complete. You will be under an anesthetic and will not feel any pain during the procedure.
Your Recovery: What to Expect?
The recovery from this advanced procedure is remarkably swift. Most people are discharged within 24 hours. You will be prescribed certain medications to take during your recovery. During healing, you will need to avoid all strenuous activities until given the okay by our heart doctor to resume exercise or sports, which is typically in about four weeks.
