Right ventricular function assessed in transhepatic view by tricuspid annular plane systolic excursion (TAPSE). (A) general transhepatic view of an ‘inverted’ four-chamber view. The TAPSE M-mode line is drawn over the image (dotted line). (B) TAPSE measurement from the transhepatic view. The systolic excursion is also inverted (downward movement in systole).
