1. a) Measurement of the right atrial a) area and b) long axis for calculation of right atrial volume. c) Measurement of the left ventricular eccentricity index in c) end-diastole and d) end-systole.
a) Measurement of the right atrial a) area and b) long axis for calculation of right atrial volume. c) Measurement of the left ventricular eccentricity index in c) end-diastole and d) end-systole. DI: minor axis perpendicular to the septum; D2: minor axis of the left ventricle parallel to the septum.
