Are there uses for cardiac CT other than coronary artery evaluation?
Cardiac CT can be used for multiple purposes beyond coronary artery evaluation. For example, another common indication is pretreatment evaluation of pulmonary vein ostia and anatomy in patients with atrial fibrillation who will undergo electrophysiologic assessment and potential ablation therapy. Cardiac masses and valvular pathology may also be evaluated by CT, although echocardiography and magnetic resonance imaging (MRI) may be more definitive. One advantage of CT is its ability to depict calcium accurately, which may be helpful to characterize certain masses and may affect treatment strategies for valvular disease.
