Use of Computed Tomography to Guide Mitral Interventions.

With increasing utilization of cardiac computed tomographic angiography (CTA) and widespread adoption of fusion imaging technology allowing the merger of pre-procedural CTA with fluoroscopy, the ability of CTA to guide structural heart interventions has evolved significantly. It has opened new possibilities in mitral valve (MV) interventions with improved pre-procedural planning and intra-procedural guidance. Given the lack of fluoroscopic landmarks of the mitral apparatus and continued growth of native MV device technologies, the value of CTA will continue to develop. The goal of this chapter is to detail the role of CTA in MV imaging and support for transcatheter therapies.
