The device is folded or attached on to a special catheter, similar to the catheter used during your 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.
DEVICE CLOSURE INTERVENTION
Is PFO DEVICE closure safe?
In our centre, we found that percutaneous closure of a PFO, which is suggested to be related to a paradoxical embolism, is a safe and effective procedure to prevent the recurrence of paradoxical thromboembolic events, independent of the device used for closure.
Conditions requiring device closure
- Patent Ductus Arteriosus – Device Closure
- Patent Foramen Ovale (PFO) – Device closure
- Atrial Septal Defect (ASD)-Device closure
- The percutaneous closure of PFO and ASD is performed using a special closure device.
