What type of anesthesia is commonly used for the transcatheter PFO occlusion procedure?
Local anesthetic, although general anesthesia or IV sedation may also be prescribed.
Is it common for the body to react negatively to the occlusion device?
Very rare
What happens to the closure device a few days after the procedure?
The patient’s body tissues begin to envelope the closure device.
How long does it typically take for the body to completely envelope the closure device?
