Heart plug may help AF patients with stomach bleeding avoid blood thinners
NCT ID NCT06052358
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked at using the WATCHMAN FLX device, a small plug placed in the heart, to prevent strokes in people with atrial fibrillation (an irregular heartbeat) who also had serious gastrointestinal (GI) bleeding. The device is meant to close off a part of the heart where clots often form, so patients might not need long-term blood thinners that can cause bleeding. The study planned to compare 250 patients who got the device to 250 similar patients who did not, but it was stopped early and enrolled only 73 people.
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 device
What this could lead to
If successful, this could offer a way to manage stroke risk in atrial fibrillation patients who have had serious GI bleeding, potentially reducing the need for blood thinners.
What could go wrong
This is a small, non-randomized registry that was terminated early, so results may be limited. The device itself carries risks like blood clots or leaks, and it may not fully prevent bleeding or stroke.
