RESUMEN

De acuerdo con un nuevo punto de vista conceptual, la insuficiencia mitral funcional es consistente con una variedad de características estructurales y dinámicas en varios escenarios clínicos con respecto a la afectación del ventrículo izquierdo (VI) y la integridad de la válvula mitral. La ecocardiografía es sin duda, la modalidad cardíaca de primera línea para la clasificación de la etiología y la gravedad de la insuficiencia mitral funcional. Sin embargo, no proporciona información completa y precisa del compromiso del VI y tiende a tener algunos errores metodológicos en los cálculos en su estimación. La resonancia magnética cardíaca es la técnica de referencia para la estimación de los volúmenes y la fracción de eyección del VI y podría integrar el estudio de la caracterización tisular del VI en varias miocardiopatías; permite la estimación cuantitativa de la gravedad de la insuficiencia valvular y podría mejorar la toma de decisiones clínicas.
