Combining 4D-ICE and TEE imaging for heart closure
Part of Brain & nervous system, Heart & circulation clinical trials.
This trial tests a new imaging method (4D-ICE) used alongside a standard ultrasound (TEE) during a heart procedure to close the left atrial appendage, a small pouch in the heart where clots can form in people with atrial fibrillation. The goal is to see if the new method makes the procedure safer and more precise.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have atrial fibrillation (irregular heartbeat) or atrial flutter.
- You are planning to have a left atrial appendage closure with a specific device (Amplatzer Amulet or WATCHMAN FLX).
- You do not have a blood clot in your left atrial appendage.
- You are not pregnant (if female).
- You are willing to follow up with our practice after the procedure.

This study tests a new 3D/4D ultrasound technology that creates detailed images of the heart during a left atrial appendage closure procedure. The goal is to see if this imaging tool helps doctors perform the procedure more safely and accurately.
This study looks at how different imaging tests can help guide a procedure that closes off the left atrial appendage to reduce stroke risk. It may help doctors choose the safest approach during the procedure.
This study compares two ways to close off a small heart pouch (the left atrial appendage) to reduce stroke risk in people with atrial fibrillation. The goal is to see which method—surgery or a less invasive tube-based approach—works better and is safer.
This trial studies a procedure to implant a Watchman device using a tiny ultrasound probe placed inside the heart, avoiding a probe in the throat. It may help patients with atrial fibrillation who need to reduce stroke risk.
This study compares two ways of closing a small pouch in the heart (the left atrial appendage) to help prevent strokes in people with atrial fibrillation (an irregular heartbeat). One method is less invasive, and the study aims to see if it is as safe and effective as the standard approach.
This study keeps a real-world record of people with atrial fibrillation who are planning a procedure to close off the heart’s left atrial appendage. Doctors use echocardiography (heart ultrasound) to guide the closure and track outcomes to improve care.
