A common clinical index of left ventricular (LV) diastolic function is the ratio of peak trans-mitral blood velocity (E) to mitral annular velocities (Em) during early diastole. Here, we provide clinical validation of a single TR, dual-echo approach wherein the first and second echoes are velocity sensitized to encode E and Em respectively.
