Key result
Multiparametric assessment of the mitral apparatus and LV predicts prognosis and repair success in DCM.
Why the study?
Left ventricular disease can alter mitral valve function and cause secondary mitral regurgitation, highlighting the need to understand mitral apparatus changes and multiparametric assessment in ischemic and nonischemic dilated cardiomyopathies.
Comprehensive multiparametric assessment of the mitral apparatus is crucial in dilated cardiomyopathy to predict prognosis and mitral valve repair outcomes.
and the papillary muscles. Due to the intricate interplay between the mitral valve and the left ventricle, a disease of the latter may influence the normal function of the former. As a consequence, valve insufficiency may arise despite the absence of organic valve disease. This is designated as functional or secondary mitral regurgitation, and it arises from a series of distortions to the valve components. This narrative review describes the normal anatomy and the pathophysiology behind the mitral valve changes in ischemic and non-ischemic dilated cardiomyopathies. It also explains the value of a complete multiparametric assessment of this structure. Not only must an assessment include quantitative measures of regurgitation, but also various anatomical parameters from the mitral apparatus and left ventricle, since they carry prognostic value and are predictors of mitral valve repair success and durability.
