What happens if a PFO or ASD is found?

If a patent foramen ovale (PFO) or atrial septal defect (ASD) is identified, your cardiologist will explain how significant the finding is and what it means for you. Many small openings don’t require any treatment and are simply monitored over time. If the connection is larger or linked to symptoms — such as a stroke, migraine with aura, or breathlessness — your consultant may recommend further assessment or closure. If closure is advised, this is usually done with a minimally invasive keyhole procedure through a vein in the leg rather than open-heart surgery. Your cardiologist will discuss the safest and most appropriate plan for you and coordinate any next steps within the Welbeck network.
