Energetic performance analysis of staged palliative surgery in tricuspid atresia using vector flow mapping

[摘要] BackgroundStaged palliative surgery markedly shifts the balance of volume load on a single ventricle and pulmonary vascular bed. Blalock-Taussig shunt necessitates a single ventricle eject blood to both the systemic and pulmonary circulation. On the contrary, bidirectional cavopulmonary shunt release the single ventricle from pulmonary circulation.Case presentationWe report a case of tricuspid atresia patient who underwent first palliative surgery and second palliative surgery. Volume loading condition was assessed by energetic parameters (energy loss, kinetic energy) intraoperatively using vector flow mapping. These energetic parameters can simply indicate the volume loading condition.ConclusionVector flow mapping was useful tool for monitoring volume loading condition in congenital heart disease surgery.
