Early Study of the Append System for Atrial Fibrillation

This early study is looking at the safety and how well a new device, called the Append System, works for people with non-valvular atrial fibrillation (an irregular heartbeat not caused by a heart valve problem). The Append System aims to close off a small pouch in the heart called the left atrial appendage (LAA), which can be a source of blood clots. The procedure involves a catheter (a thin tube) to invaginate and ligate (tie off) the LAA tissue. We are looking for people aged 18 or older with non-valvular AF and a CHA2DS2-VASc score of 2 or higher for males, or 3 or higher for females. The main goal is to see if there are any major problems within 30 days after the procedure. The study is currently unclear on its recruitment status and plans to enroll 15 participants.

Study design
This is an interventional study, meaning participants will receive a specific treatment. It is an early feasibility study, and 15 participants are planned.
What's involved
Patients will be followed for up to 5 years after the procedure to check on safety and how well the device works.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 5 years after the procedure.
