Summary

This study examines whether closing the left atrial appendage with a device called AMULET changes how well the heart relaxes. It includes 100 adults with atrial fibrillation who are at high risk for stroke but cannot take blood thinners. Researchers measure heart function using ultrasound before and after the procedure to see if it stays the same.

What this could mean

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

Active substance
percutaneous closure of the left atrial appendage using the St Jude AMULET device
What this could lead to
If successful, this study could show that left atrial closure does not harm heart function, supporting its use as a safe alternative to blood thinners.
What could go wrong
This is a small, early observational study focused on a specific measurement, not on long-term outcomes. The results may not apply to all patients.
