Abstract:
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.

Imaging Studies for Cardiovascular System V: CT
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
