Role of computed tomography in transcatheter coronary and structural heart disease interventions.

Computed tomography is a noninvasive imaging technique with high spatial resolution, providing excellent definition of calcium and intravascular space through the use of contrast media. This imaging modality allows both highly accurate measurements and virtual simulations for preprocedural planning in coronary and structural heart disease interventions. Computed tomography is currently the gold standard technique for patient selection and preprocedural planning in numerous scenarios, such as transcatheter aortic valve implantation, left atrial appendage occlusion, transcatheter mitral valve repair, and transcatheter tricuspid valve repair. This article reviews the role of computed tomography in transcatheter coronary and structural heart disease interventions.
