Is There An Optimal Time For The Completion Of Total Cavopulmonary Connection After Bidirectional Glenn Anastomosis?

摘要

Background: This retrospective study aims to explore whether there is a safe maximum waiting period for completion of TCPC (total cavopulmonary connection) after bidirectional Glenn (BDG) anastomosis. Methods: This study includes 42 patients, who had 2 or more years follow-up following BDG. Our policy has been to perform TCPC only, when we had arterial oxygen saturation (SaO_2) deterioration and/or parental dissatisfaction of their child's health. We assessed SaO_2, physical growth, parental assessment of child's health, ventricular function, AV valve regurgitation, and systemic ventricle volume index data immediately after the operation, after 2 years (usual TCPC completion period) and during the last visit. Results: The mean follow-up of the 42 patients was 66.2130 (24-147) months. SaO_2, systemic ventricular ejection fraction and systemic ventricle volume index remained unaffected during the follow-up period.
