NCT ID NCT07262255

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is tracking 1000 people with atrial fibrillation who receive the WATCHMAN FLX Pro device, a small implant that closes off a part of the heart to prevent blood clots from causing strokes. The goal is to see how safe and effective the device is in everyday medical practice, especially for patients who cannot take long-term blood thinners. Researchers will monitor for serious events like stroke, bleeding, or death within a week of the procedure.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

WATCHMAN FLX Pro device (a left atrial appendage closure implant)

What this could lead to

If successful, this registry could confirm that the device safely reduces stroke risk and bleeding events in people with atrial fibrillation who cannot take blood thinners.

What could go wrong

This is an observational registry, not a controlled trial, so results may not prove cause and effect. There are procedural risks like bleeding, stroke, or need for emergency surgery.
