Measurements of tricuspid annular plane systolic excursion (TAPSE; left) and right ventricular longitudinal systolic strain (LSsys; right) derived from two-dimensional speckle tracking imaging at the final examination (August 2013). Solid-colored lines indicate corresponding segmental strain curves and white dashed line indicates global strain curve on the right panel. Note the considerably reduced measurement values for TAPSE (normal range: >20 mm) and right ventricular global LSsys (−11%). Lat: RV lateral wall; RA: right atrium; RV: right ventricle; Sept: interventricular septum.
