RESUMO
Computed tomography (CT) plays a key role in the peri-procedural planning of left atrial appendage occlusion (LAAO) device placement and post-procedural evaluation. The geometric variability of the interatrial septum, left atrium, and the left atrial appendage morphology can be fully visualized and intuitively appreciated through CT-derived, patient-specific 3D model unique to each individual's anatomy. This review further defines the strengths and limitations of CT peri-procedural imaging in the planning of LAAO.
RESUMO
Three-dimensional (3D) printing is a process leading to the creation of a physical 3D model used for teaching, patient education, device evaluation, and procedural planning. 3D printed models of patient-specific anatomy can be generated from 3D transesophageal, cardiac MRI, or cardiac computed tomographic datasets. This article discusses the potential advantages of 3D printing, reviews the different modalities to acquire a 3D dataset, and highlights the application of 3D printing to enhance patient screening and procedural planning in structural heart intervention.
