How does structural heart disease affect candidacy for LAAO?

Structural heart disease significantly complicates the procedure of Left Atrial Appendage Occlusion (LAAO) and can impact device positioning. Conditions such as atrial enlargement, fibrosis, or prior cardiac surgeries can alter the anatomy of the heart, making it more challenging to navigate and position the occlusion device correctly. Any structural abnormalities may increase the risk of complications during the procedure, necessitating careful pre-procedural evaluation and potentially influencing the decision on whether to proceed with LAAO. Understanding the implications of structural heart disease is essential for achieving favorable procedural outcomes and ensuring patient safety.
