Abstract:Background: Left atrial appendage occlusion (LAAO) has historically been
performed using intraprocedural transesophageal echocardiography (TEE)
and fluoroscopy. Multiple recent reports have described the feasibility
and advantages of utilizing two-dimensional intracardiac
echocardiography (ICE) for LAAO. However, in inexperienced hands, safe
manipulation of the ICE catheter in the left atrium (LA) can be
challenging. Objective: To assess the feasibility and efficacy of
three-dimensional (3D) ICE mapping in gui… Show more
