Read our Atrial Fibrillation research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a simpler imaging approach works just as well as a more comprehensive imaging approach when doctors perform left atrial appendage closure — a procedure that seals off a small pouch in the heart to reduce stroke risk. The study will compare how safely and effectively each approach guides the procedure and catches any complications afterward.
Many patients with irregular heartbeats cannot safely take blood-thinning medications due to bleeding risks, so they need alternative ways to prevent strokes. This trial wants to see if doctors can use fewer imaging tests during this procedure without sacrificing safety or effectiveness, which would make the procedure easier and less burdensome for elderly and frail patients.

You will be randomly assigned to receive either a standard or comprehensive imaging approach before, during, and after your left atrial appendage closure procedure. Before the procedure, you will have imaging scans to plan the surgery. During the procedure, your doctors will use imaging to guide placement of the device. After the procedure, you will have follow-up imaging to check for any complications. The study tracks how much radiation, contrast dye, and procedure time each approach requires.
