Cardiac computed tomography (CT) is an imaging modality that can visualize the anatomy of the heart and its surroundings. The technological advancement in cardiac CT gave better accuracy with lower radiation than earlier models. Its entire procedure took a relatively short time and minimal contact. Cardiac CT is an important imaging modality in clinical practice during emergencies and non-emergency settings and in planning comprehensive management of cardiac patients. Cardiac CT is useful in emergency settings, acting as a triple rule-out imaging modality. Cardiac CT in non-emergency settings can determine coronary artery calcium (CAC) score and detect left atrial appendage (LAA) thrombus before cardioversion. Furthermore, cardiac CT is now more commonly used as a modality in planning comprehensive management of cardiac patients’ especially coronary CT angiography (CCTA) in planning for cardiac intervention. This imaging modality becomes more relevant to use in clinical practice during the pandemic due to less contact with the patient needed during the procedure, and physicians may get used to cardiac CT. This article aims to explain the advantages of CCTA in emergency and non-emergency settings and discuss its limitation so that we can make the best use of it. This writing is a literature review.

La tomografía computarizada (TC) cardíaca es una modalidad de imagen que puede visualizar la anatomía del corazón y su entorno. El avance tecnológico en la TC cardíaca brindó una mayor precisión con una radiación más baja que los modelos anteriores. Todo su procedimiento tomó un tiempo relativamente corto y un contacto mínimo. La TC cardíaca es una modalidad de imagen importante en la práctica clínica durante emergencias y entornos que no son de emergencia y en la planificación del manejo integral de pacientes cardíacos. La TC cardíaca es útil en situaciones de emergencia, ya que actúa como una modalidad de imagen de triple exclusión. La TC cardíaca en entornos que no son de emergencia puede determinar la puntuación de calcio en la arteria coronaria (CAC) y detectar trombos en el apéndice auricular izquierdo (LAA) antes de la cardioversión. Además, la TC cardíaca ahora se usa más comúnmente como una modalidad en la planificación del manejo integral de pacientes cardíacos, especialmente la angiografía por TC coronaria (CCTA) en la planificación de una intervención cardíaca. Esta modalidad de imagen se vuelve más relevante para su uso en la práctica clínica durante la pandemia debido a que se necesita menos contacto con el paciente durante el procedimiento, y los médicos pueden acostumbrarse a la TC cardíaca. Este artículo tiene como objetivo explicar las ventajas de CCTA en entornos de emergencia y no emergencia y discutir su limitación para que podamos hacer el mejor uso de ella. Este escrito es una revisión de la literatura. La búsqueda bibliográfica utilizando PubMed y Google Scholar.
