- 10:23Conclusion
The closure of a patent foramen ovale (PFO) is a catheter-based intervention to prevent PFO-associated stroke. The PFO-occlusion device is advanced through the femoral vein and deployed across the interatrial septum using transesophageal echocardiography (TEE) and fluoroscopic guidance. The following protocol provides a step-by-step guide for the PFO-closure intervention using a double-disc device.
