Heart hole closure may rewire migraine brains, study hints
NCT ID NCT07343154
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at 45 adults with migraine and a small hole in the heart (PFO). Researchers will use brain scans and thinking tests to see if closing the hole changes brain activity, mood, and migraine symptoms over a year. The goal is to understand the link between PFO and migraine, not to prove a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- percutaneous patent foramen ovale (PFO) closure procedure
- What this could lead to
- If successful, this study could clarify whether closing a PFO improves brain function and reduces migraine burden, pointing toward a better understanding of migraine mechanisms.
- What could go wrong
- This is a small, early-phase observational study (45 participants) that does not test a new drug or therapy. It may not show clear benefits, and results may not apply to all migraine patients.
