References This is an open-access article distributed under the terms of the Creative Commons Attribution License advanced aortic valvopathy have higher ventricular mass and reduced ejection fraction, when compared with the healthy group. In this context, measures of systolic and diastolic function can be expected to differ from those of the healthy control group. As a suggestion for future studies, the inclusion of other variables, easily obtained in the basic cMRI sequences, such as left atrial volume (a chronic marker of diastolic dysfunction and cardiovascular risk) or the presence of late LV enhancement (indicator of fibrosis as a potential substrate for myocardial impairment) would certainly add important data to the debate on the role of cMRI in LV diastolic dysfunction. Moreover, it would be interesting to perform its validation with methods that are clinically used as invasivemeasures of the Tau constant, or through echocardiography parameters, which are validated measures for the analysis of diastolic function in different heart diseases. 294
