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.
