Summary

This trial studies if a new imaging tool can provide better visualization of the heart's anatomy and help guide procedures to close off the left atrium. 52 people will be followed for 12 months.

Who is the study for?
This trial is for men and women aged 18-80 with a history of atrial fibrillation or flutter who are scheduled for a procedure to close off a part of the heart called the left atrial appendage using specific devices. It's not for those with blood clots in that area, pregnant individuals, patients with complex heart anatomy, or those unwilling to consent.
What is being tested?
The study tests if 4D Intracardiac echocardiography (a type of advanced heart imaging) can provide as clear images as Transesophageal echocardiography during left atrial appendage closure procedures. About 52 participants will be observed over one year without being randomly assigned to groups.
What are the potential side effects?
While this trial focuses on imaging techniques rather than medications, potential side effects may include discomfort from the imaging equipment and risks associated with standard procedural complications.
