DEA-LAA Trial Summary

This trial is designed to see if dabigatran can prevent device-related thrombus (clots) after a Watchman LAA closure device is implanted.

Who is the study for?
This trial is for adults over 18 with atrial fibrillation who need a Watchman LAA closure device and have a moderate to high stroke risk (CHADS2 Vascular score of 3-9) and bleeding risk (HAS BLED score ≥2). They must be able to consent, expect to live more than a year, and not require long-term anticoagulation for other conditions. People allergic to aspirin or dabigatran, with recent major bleeding or certain heart issues are excluded.Check my eligibility
What is being tested?
The study tests if taking dabigatran etexilate capsules for 90 days after getting the Watchman LAA closure device can prevent blood clots without causing significant side effects. It's an unblinded study at Vanderbilt Medical Center and up to five other centers involving patients who meet specific criteria.See study design
What are the potential side effects?
Dabigatran may cause bleeding problems, digestive tract discomfort, potential allergic reactions in those sensitive to its ingredients, and increased risk of developing blood clots if stopped abruptly.
