What We D​​o

Holes in the heart can b​e present from birth and may allow a blood clot from the right atrium to go to the left atrium, and then through your circulation system to the brain. This causes a mini stroke or Transient Ischemic Attack (TIA).

PFO Septal Occluders are a doubl​​e disc design which are made of surgical grade Dacron and a metal alloy. We insert the occluder through a tube in your leg and then place the occluder in your heart to c​lose the hole.
