Abstract

Heart failure is not always due to an alteration in systolic function, and a diastolic dysfunction could explain many cases of heart failure with a normal systolic function. Diastolic function depends on the left ventricular filling capacity to ensure a normal stroke volume. It is routinely measured with transthoracic echocardiography, as it is an easily accessible non-invasive test. The magnetic resonance imaging (MRI), using flow sequences, shows good agreement with the echocardiography, analysing the diastolic function in a practical way, by the flow into the mitral valve and pulmonary veins. In this sense, the analysis of diastolic function should be added as part of a routine cardiac MR examination.

Resumen

La insuficiencia cardíaca no siempre es debida a una alteración sistólica, y una disfunción diastólica puede explicar muchos casos de insuficiencia cardíaca con función sistólica normal. La función diastólica depende de la capacidad de llenado del ventrículo izquierdo para garantizar un volumen latido normal. Se mide rutinariamente con la ecocardiografía transtorácica, ya que se trata de una prueba no invasiva y de gran accesibilidad. La resonancia magnética (RM), utilizando secuencias de flujo, muestra una buena concordancia con la ecocardiografía, analizando la función diastólica de forma práctica, a través del flujo en la válvula mitral y las venas pulmonares. En este sentido, el análisis de la función diastólica debería añadirse como parte de un examen rutinario de RM cardíaca.
