It is time to think about further optimization of the echocardiographic assessment of left ventricular responses to mitral regurgitation

Left ventricular ejection fraction (LVEF) is still used as a key determinant of LV function and timing in mitral regurgitation (MR) intervention in patients with chronic primary MR, although its load dependency and its misleading overestimation of LV pump function in the presence of MR are generally accepted [1]. Even the evidence that the easily measurable forward LVEF (i.e. LV forward stroke volume/end-diastolic volume) can be independently associated with life-threatening aggravation of MR in patients with nearly identical total LVEF and LV global longitudinal strain values [2,3], has not changed that opinion.
