What this trial studies

This study evaluates the effectiveness of a semi-automatic 3D echocardiography-based planning method for left atrial appendage occlusion (LAAO) compared to the traditional CT-based approach. It involves measuring the dimensions of the left atrial appendage and predicting device sizing and deformation using both imaging techniques. The study will analyze the success rate of the 3D echocardiography method in providing complete reports and compare it to the established gold standard. Various endpoints will be assessed to determine the feasibility and accuracy of this new approach.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for LAAO with an Amplatzer Amulet device at participating Belgian centers.

Not a fit: Patients with contraindications for contrast or radiation exposure, or those unable to undergo CT analysis will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the precision of LAAO procedures, leading to better patient outcomes.

How similar studies have performed: While similar imaging approaches have been explored, this specific comparison of 3D echocardiography with CT for LAAO planning is relatively novel.
