This procedure is performed in the cardiac catheterisation lab. You will be given an anaesthetic which may be general (GA) or local (LA) depending on the technique used. In most cases, this procedure is performed under general anaesthetic (GA) which is given by a qualified anaesthetist. Once anaesthetised, an imaging probe (TEE) will be passed into your gullet (oesophagus) for accurate assessment of the PFO and to assist during deployment of the device. You will lie on an X-ray table and an X-ray camera will move over your chest during the procedure. A plastic catheter (a long tube) will be inserted via a vein in the groin and navigated until it reaches the heart. Sometimes (depending on individual case), the catheter is position at different chambers of your heart to measure the pressure and oxygen content prior to device closure. In certain circumstances, balloon sizing of the PFO may be required. Once your doctor is satisfied with all the measurements, the appropriate size device is connected onto a cable, put into a special delivery tube, advanced through your PFO and carefully deployed. Your doctor will study the device’s position and stability before releasing the device. The catheter and imaging probe are removed and the procedure is completed.
