After birth, his oxygen saturation was around 60%, and no ductus arteriosus was detected. A systemic-to-pulmonary shunt was placed emergently. After surgery, antegrade blood flow from the right ventricular outflow tract was unstable depending on the right ventricular muscle contraction and relaxation, and the antegrade blood flow needed to be occluded. The postoperative course was uneventful after then.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>This case underscores the complexity of managing neonates with tricuspid atresia, severe RVOTO, and PCDA.
