Figure 2. Representative images from high resolution echocardiography systems.
A) Representative image of M-mode image used for assessment of cardiac systolic function (AW = anterior wall, PW = posterior wall, LVEDD = left ventricular diastolic dimensions, LVESD = left ventricular systolic dimensions; arrows denote the thickness/dimension of interest for each variable). B) Representative image of pulsed-wave Doppler assessment of peak mitral valve inflow (E) using color Doppler guidance (IVRT = isovolumic relaxation time, IVCT = isovolumic contraction time, LVET = left ventricular ejection time). C) Representative image of tissue Doppler assessment of the septal mitral annulus velocity (e’) using the spectral velocity display. White arrows denote the point of measurement.
