Multidetector cardiac computerized tomography (CT) is a robust advanced imaging modality with high spatial resolution that has emerged as an essential tool for the planning of structural heart and electrophysiology interventions. The most notable example has been its important role in the pre-procedural planning of transcatheter aortic valve replacement (TAVR), which has developed to the point that commercial software packages are commonly used for this application. More recently several novel approaches and devices have been developed for transcatheter mitral valve replacement (TMVR). Given the greater complexity of mitral valve anatomy, CT has at least an equally important role for preprocedural planning of TMVR. Similar to TAVR assessment, its utility in TMVR is multi-fold, including assessment of valve and adjacent anatomical structures, determination of accurate annulus dimensions for prosthesis sizing, vascular access planning, and prediction of fluoroscopic angles.
