You can generally expect that:. For a while after the procedure, you may also need to take antibiotics before certain medical and dental procedures. It will help prevent an infection of the heart valves. Ask your healthcare provider if you will need to do so.
Health Home Treatments, Tests and Therapies. Why might I need patent foramen ovale transcatheter repair? What are the risks of patent foramen ovale transcatheter repair?
Possible risks include: Abnormal heart rhythms. These can cause sudden death in rare instances. Device becoming unattached and traveling through the heart or vessels Tear in the blood vessels around the heart Infection Excess bleeding Puncturing of the heart rare Stroke There is also a risk that the procedure will not fix the PFO.
How do I get ready for patent foramen ovale transcatheter repair? Your healthcare provider may want some extra tests before the procedure.
These might include: Chest X-ray Electrocardiogram to look at your heart rhythm Blood tests to check general health Echocardiogram to look at the heart anatomy and blood flow through the heart Transcranial and transmitral Doppler to see the blood moving through the heart Bubble study that is used with the 2 above tests to view the PFO Hair from around the catheter insertion site may be removed before the procedure.
What happens during patent foramen ovale transcatheter repair? In general: A healthcare provider will probably give you anesthesia before the surgery starts.
You will sleep deeply and painlessly during the operation. The repair will take about 2 hours. The healthcare provider inserts a small, flexible tube catheter into an artery in the groin. This tube will have a small device inside it.
The provider threads the tube through the blood vessel all the way to the PFO. The provider may use X-ray images and an echocardiogram to see exactly where the tube is. The provider will push the small device out of the tube and plug the hole in the PFO. Then the device will be secured in place.
The provider will remove the tube through the blood vessel. The insertion site will be closed and a bandage will be applied. What happens after patent foramen ovale transcatheter repair? You can generally expect that: You will spend several hours in a recovery room. Your vital signs will be closely watched. These include your heart rate, blood pressure, oxygen levels, and breathing.
You may need to lie flat for several hours after the procedure without bending your legs. The pressures in the lungs and heart are recorded. The procedure is performed under local anaesthetic, meaning you will be awake throughout it. After a small incision is made in the groin and a long, thin tube called a catheter is inserted into a vein. The PFO closure device is then guided through the catheter to the heart. Once there the device is implanted, or anchored, and then adjusts to the unique anatomy of your heart.
Soon after the PFO closure device is implanted, tissue begins to form and eventually cover the device completely. This process of tissue formation is medically known as endothelialisation.
It is important because it helps prevent blood in the left atrium from reacting with the exposed device and forming clots called thrombosis. Patients are generally discharged from hospital the day after the procedure. You will be reviewed by your doctor prior to discharge. One of our staff members will be in contact with you to arrange a follow-up appointment in the rooms in the near future.
Alternatively, the console can be covered with a sterile sleeve and positioned to the right of the caudal-most end of the table. This allows the scrubbed interventionalist or the assistant to operate the ICE machine throughout the procedure. We advance the ICE catheter under fluoroscopy via a long 30 cm sheath to avoid manipulation of the catheter in the pelvic veins. Figure 1. Device deployment in the long-axis view D, E. Final short-axis view after device deployment F. Interrogation of the septum and its adjacent structures in the short- and long-axis views allows a comprehensive survey of certain high-risk features of the PFO that may have important technical implications on the procedure.
Under fluoroscopy, we exchange the straight wire with a J-tip Amplatz Extra Stiff wire Cook Medical , which is then advanced and parked in the left superior pulmonary vein. Both are available in three sizes: 20, 25, and 30 mm for the Cardioform septal occluder and 18, 25, and 35 mm for the Amplatzer PFO occluder. We use the mm Cardioform septal occluder or the mm Amplatzer PFO occluder for most patients, but we often use the smaller devices in smaller-sized hearts and the larger devices if high-risk PFO features exist eg, septal aneurysm, thick septum secundum.
Other devices Amplatzer cribriform occluder [Abbott Vascular], Amplatzer septal occluder [Abbott Vascular] are often used off-label to ensure complete sealing in patients with high-risk PFO features. We advance the deaired device delivery system over the Amplatz Extra Stiff wire into the left atrium and then remove the Amplatz Extra Stiff wire.
The Cardioform septal occluder is typically preloaded into the delivery system, which minimizes the risk of air embolism. However, it is essential to maintain a wet-to-wet connection and avoid deep inspiration when an Amplatzer device is loaded into the delivery system because these situations carry a higher risk of air embolism. Once the device is advanced into the left atrium, the left-sided disc is unsheathed and pulled against the septum Figure 1D.
The position and seal of the device are confirmed by two-dimensional and color Doppler ICE imaging in the short- and long-axis views. Device-specific securing mechanisms are then applied tug test for Amplatzer and loop locking for Cardioform , and further evaluation with ICE is performed Figure 1E and 1F. When satisfactory position, stability, and seal are ensured, the device is released under ICE and fluoroscopic guidance. The procedure is concluded by a final ICE survey with a clockwise sweep of the probe, starting at the home view to rule out pericardial effusion.
Hemostasis can be achieved with a figure-of-eight 0 silk suture and additional manual pressure for 5 minutes. First, advancement of the ICE catheter through the iliac veins and inferior vena cava can lead to vascular damage. Resistance while advancing the probe or sudden abdominal pain during the procedure should be further investigated with a venogram to rule out a major vascular complication. Second, manipulation of the ICE catheter can often induce premature atrial or ventricular contractions or transient complete heart block, which are usually self-limiting and resolve with correction of the catheter position.
Third, although ICE use can theoretically lead to more vascular complications additional venous puncture and pericardial effusion, the risk of these complications with ICE-guided PFO closure is very small.
