^†, variables included in the multivariable model at 1-year for risk-adjustment: gender, race, bilirubin level, implant year, intermacs profile, left ventricular assist device type; ^‡, variables included in the overall mortality model for risk-adjustment: gender, race, bilirubin level, implant year, prealbumin level, intermacs profile, mean pulmonary artery pressure, left ventricular assist device type. LVEDD, left ventricular diastolic diameter; LVAD, left ventricular assist device.
