RESUMEN
La enfermedad valvular cardíaca es un problema clínico que se ha estudiado con técnicas de imagen clásicas como la ecocardiografía o la RM. El avance tecnológico de la TC permite obtener imágenes estáticas y dinámicas con las que hacer un análisis morfológico y, en muchas ocasiones, funcional. A pesar que actualmente está solo indicada en los pacientes en los que la ecocardiografía o la RM no son concluyentes o están contraindicadas, la TC multidetector permite diagnosticar la estenosis o insuficiencia por planimetría, valorar y cuantificar el calcio valvular, y mostrar las repercusiones funcionales en el resto de estructuras cardíacas. Teniendo en cuenta que la TC multidetector es una técnica cada día más utilizada para el diagnóstico de la enfermedad isquémica, creemos interesante que el radiólogo conozca la potencialidad que esta técnica tiene en el estudio de la afección valvular (AU)

Although it is currently indicated only in patients with inconclusive findings at echocardiography and MRI or those in whom these techniques are contraindicated, multidetector CT makes it possible to diagnose stenosis or regurgitation through planimetry, to evaluate and quantify valvular calcium, and to show the functional repercussions of thesephenomena on the rest of the structures of the heart. Given that multidetector CT is being increasingly used in the diagnosis of ischemic heart disease, we think it is interesting for radiologists to know its potential for the study of valvular disease (AU)
