Mitral valve inflow doppler
WebMitral annular plane systolic excursion was measured in the apical four-chamber views at the lateral side of the annulus as systolic excursion of the annulus from its lowest point at end-diastole to its highest point at the time of aortic valve clo-sure(26). LV cardiac strain was assessed in the pre-defined two- Webtion, the ratio of the E wave of the left ventricular inflow velocity waveform to the e' wave of the mitral annular ve-locity, E/e', differs from heart beat to heart beat. LA strain has also been reported to be a useful index in patients with AF, and a decrease in left atrial strain has been reported to be associated with cardiovascular events.
