Comparing Steerable Sheaths for Left Atrial Appendage Closure

This study is looking at how a new, steerable delivery sheath compares to a traditional, non-steerable sheath when closing the left atrial appendage (LAA) with the Amplatzer™ Amulet™ device. The LAA is a small pouch in the heart where blood clots can form, leading to stroke in people with atrial fibrillation (an irregular heartbeat). Researchers want to see if the steerable sheath helps achieve better closure of the LAA. You may be able to join if you have atrial fibrillation and are scheduled to have your LAA closed with the Amplatzer™ Amulet™ device. The study will measure how many people achieve immediate closure of the LAA, and look for complications like heart perforation (a small hole in the heart) or the need for pericardiocentesis (a procedure to remove fluid around the heart) within 7 days. The current status of this study is unclear.

Study design
This interventional study plans to enroll 300 participants. It compares two different types of sheaths used during the LAA closure procedure.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for acute closure of the LAA at 1 day, and for cardiac perforation and need for pericardiocentesis at 7 days.
