  Fig. 1.. M-mode echocardiography-derived measurement of tricuspid annular plane systolic excursion (TAPSE). Abbreviations: TAPSE, tricuspid annular plane systolic excursion; RA, right atrium; RV, right ventricle; LA, left atrium; LV, left ventricle.

  Fig. 2.. Analysis of the rotational mechanics of the left ventricle (LV) by three-dimensional (3D) speckle-tracking echocardiography. Apical longitudinal four-chamber (A) and two-chamber views (B) and short-axis views at apical (C3), midventricular (C5) and basal LV levels (C7) are shown together with a 3D model of the LV (D) and calculated LV volumetric data (E). Time - LV apical (yellow arrows) and basal (dashed yellow arrows) rotation curves are shown together with time - LV volume change curve during the cardiac cycle (F). Abbreviations: EDV, end-diastolic volume; ESV, end-systolic volume; EF, ejection fraction; RA, right atrium; RV, right ventricle; LA, left atrium; LV, left ventricle.

  Fig. 3.. Assessment of the right atrium by three-dimensional (3D) speckle-tracking echocardiography. Apical four-chamber (A) and two-chamber views (B) and short-axis views at basal (C3), midatrial (C5) and superior RA levels (C7) are demonstrated together with a 3D RA cast (D) and calculated RA volumes (E). Time - RA volume changes curve represented by a white dashed line is also shown (F). Abbreviations: LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle; EDV, end-diastolic volume; ESV, end-systolic volume; EF, ejection fraction; Vmax, maximum RA volume; VpreA, pre-atrial contraction RA volume; Vmin, minimum RA volume.
