*, RV inferior wall was measured at the short axis cine slice location similar to the OS-CMR mid ventricular slice location. OS, oxygen-sensitive; CMR, cardiovascular magnetic resonance; RV, right ventricle; LV, left ventricle; LVEF, LV ejection fraction; RVEF, RV ejection fraction; ESVi, end-systolic volume index; EDVi, end-diastolic volume index; SV, stroke volume; ED, end-diastolic.
