a Bar graphs of the right ventricular end-diastolic volume indexed to body surface area (RVEDVI) and right ventricular ejection fraction (RVEF) before and after anesthesia induction are shown. No changes were observed regarding RVEDVI and RVEF. Right side shows an example of a volumetric model of the right ventricle together with an example of results given by the Tomtec 4D RV-function software. b Bar graphs of the tricuspid annular plane systolic excursion (TAPSE) and tissue Doppler-derived peak systolic velocity of the lateral tricuspid annulus (TDI TV s’) before and after anesthesia induction are shown. Significant reductions were observed for the TAPSE and TDI TV s’. Right side shows examples of the TAPSE measurement in M-Mode and the measurement of the TDI TV s’ in tissue spectral Doppler. c Bar graphs of the right ventricular peak systolic free wall strain (3DRVLS-fw) and septal wall strain (3DRVLS-sw) are shown. A significant decrease in 3DRVLS-fw was observed with no change in 3DRVLS-sw. Right side shows an example of the strain measurements in reconstructed 3D datasets
