  1. *Baseline adjustments for age at surgery, sex, body mass index (BMI), hematocrit, SpO2, left ventricular end-diastolic volume (LVEDV), and NYHA classification
  2. #Clinical adjustments for added clinical factors including McGoon ratio, pulmonary annular Z-score, and aortopulmonary collateral arteries (APCAS)
  3. $Procedural adjustments for added factors including cardioplegia types, transannular patch, tricuspid valve detachment, cardiopulmonary bypass (CPB) time, and intraoperative blood transfusion, immediately postoperative central venous pressure (post-CVP), and transpulmonary gradient (post-TPG)
