Closure devices are used to close a defect of an opening between the right and left sides of the heart. Both of these congenital disabilities are located in the wall (septum) between the upper chambers (atria) of the heart.

Patent Foramen Ovale (PFO):

The foramen ovale is a hole in the septum between the left and right atria of a human fetus. The foramen ovale closes as blood pressure rises in the left side of the heart after birth. However, when the foramen ovale does not close properly at birth, there is still an opening in the septum. This is known as a patent foramen ovale (PFO).

Atrial Septal Defect (ASD):

An atrial septal defect is a hole in the septum that occurs when the septum does not form properly. This condition is also commonly known as a “hole in the heart.”

PFO/ASD Closure 

The percutaneous closure of PFO and ASD is performed using a special closure device. The device is folded or attached to a special catheter, similar to the catheter used during cardiac catheterization. The catheter is inserted into a vein in the leg and advanced into the heart and through the defect. 

The device is slowly pushed out of the catheter, allowing each side of the device to open up and cover each side of the hole (like a sandwich), closing the hole or defect. When the device is in the proper position, it is released from the special catheter.

Over time, heart tissue grows over the implant, becoming part of the heart. The PFO and ASD closure procedures are monitored by X-ray and an ultrasound camera inserted in the heart from a vein in the top of the leg. 

Most patients return to work within one week. Activity restrictions may include:

  • No heavy lifting, pushing or pulling greater than 10 pounds for 5 days
  • No driving for 5 days
  • No heavy activity that causes heavy breathing for 6-8 weeks
