ECMO = extracorporeal membrane oxygenation; IABP = intra-aortic balloon pump; LV = left ventricle; LVEDD = left ventricle end diastolic diameter; MCS = mechanical circulatory support; PCWP = pulmonary capillary wedge pressure; RAP = right atrial pressure; RVEDD = right ventricle end diastolic diameter; TAPSE = tricuspid annular plane systolic excursion; TR = tricuspid regurgitation; other abbreviation as in Table 1.

  • On pre-operative right heart catheterization.

  • Including ECMO, Impella, or RVAD.
