Fig 1. Representative images of echocardiographic assessment of right ventricular systolic function.

Fig 1

(A) %RVFS [(a–b)/a × 100%]; (B) percentage RV area change [(a–b)/a × 100%]; (C) TAPSE; (D) right ventricular MPI [(a–b)/b]; and (E) TVlat. See text for further information on how these indices were obtained or calculated. LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle.
