Abstract

The updated Coronary Artery Disease Reporting and Data System (CAD-RADS 2.0) adds new features for patients undergoing coronary CT angiography (CCTA). The following features are included in the new system: stenosis severity (categories 0, 1, 2, 3, 4A, 4B and 5), the overall amount of coronary plaque (from P1 to P4), classic modifiers (the study is not fully evaluable, presence of stents or grafts), new modifiers (if a myocardial ischemia test with CT is performed, I+ or I−), exceptions, and presence of high-risk plaques (HRP). This updated classification adds new features to guide patient management, including functional assessment in cases of CAD-RADS 3, CAD-RADS 4A, 4B and 5, and invasive coronary angiography in cases of CAD-RADS 3/I+, 4A, 4B and 5. This work aims to analyse the new modifications introduced in the updated system, understand the implications in patient management, and review teaching cases.

Resumen

El nuevo sistema Coronary Artery Disease Reporting and Data System (CAD-RADS 2.0) aporta aspectos actualizados dirigidos a pacientes sometidos a coronariografía por tomografía computarizada (CTC). Incluye los siguientes ítems: severidad de la estenosis (según las categorías 0, 1, 2, 3, 4A, 4B y 5), carga total de placa coronaria (de P1 a P4), modificadores clásicos (estudio no evaluable, presencia de stents o de injertos), modificadores nuevos (incluyendo pruebas de detección de isquemia por TC, I + o I−), excepciones y placas de alto riesgo. Se añaden recomendaciones para guiar el manejo del paciente, considerando una prueba funcional para los casos CAD-RADS 3, 4A ó 5; y la coronariografía convencional para los casos CAD-RADS 3/I+, 4A, 4B ó 5. Los objetivos de este trabajo son estudiar las nuevas modificaciones del nuevo sistema, entender las implicaciones de este en el manejo del paciente y revisar ejemplos de casos didácticos.
