Definition of calliper distances. Yellow—left ventricle (LV). Blue—right ventricle (RV). HRV—the distance between tricuspid valve (TV) centroid and RV apex. HLV—the distance between the mitral valve (MV) centroid and RV apex. WRV—the distance between the RV free wall and the septum measured at mid RV height (r*HRV, r = ½) on the axis perpendicular to the septum. WLV—the distance between the LV endocardium and the septum measured at mid-LV height (r*HLV, r = ½) along the axis perpendicular to the septum. LRV—the distance between the two most distant points on the RV free wall at mid RV height (½*HLV) along the axis parallel to the septum
