New device seals Stroke-Causing heart pouch during bypass surgery
NCT ID NCT07360899
First seen Jan 23, 2026 · Last updated Jun 22, 2026 · Updated 21 times
Summary
This study tests a device called AtriLASH that closes a small heart pouch (the left atrial appendage) during planned heart surgery in 200 people with atrial fibrillation. The goal is to prevent blood clots that cause strokes, potentially reducing the need for blood-thinning medications. Researchers will check if the pouch stays closed after 3 months and track any strokes or bleeding events.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
AtriLASH device (suture-based closure device made of Seralene material)
What this could lead to
If successful, this could offer a safer way to reduce stroke risk in atrial fibrillation patients undergoing heart surgery, potentially allowing some to stop long-term blood thinners.
What could go wrong
This is a single-arm study with no comparison group, so benefits are uncertain. The device may not fully close the appendage, and risks like bleeding or embolism remain. Long-term stroke reduction is not yet proven.
