Intracardiac Echocardiography Guided Watchman Device Implant

This study is comparing two guidance techniques for implanting a Watchman device — a small plug used to close off part of the heart (the left atrial appendage) in people with atrial fibrillation (AFib) to reduce stroke risk. One method uses a camera inside the heart (intracardiac echocardiography), while the usual method uses a camera down the throat (transesophageal echocardiography). **You may be eligible if:** - You meet standard clinical guidelines for receiving a Watchman device - You are not already enrolled in another active clinical trial **You may NOT be eligible if:** - A camera down the throat (TEE) cannot be performed and a heart camera (ICE) only approach is needed - You are having an additional ablation procedure at the same time - You have had a prior incomplete procedure to close off the left atrial appendage - Your anatomy makes the procedure technically difficult (e.g., you have a PFO or ASD closure device in place) Talk to your doctor to see if this trial is right for you.
