Key result
Anatomical correction restoring a systemic left ventricle improved tricuspid regurgitation with 11% mortality, whereas conventional surgery leaving the right ventricle in systemic position had 33% mortality.

How do different surgical interventions affect tricuspid valve function in children with double discordance and an abnormal tricuspid valve?
In patients with double discordance and an abnormal tricuspid valve, interventions that decrease right ventricular volume or increase left ventricular pressure (such as anatomical correction) improve tricuspid valve function, whereas conventional surgery leaving the right ventricle in the systemic position leads to failure of tricuspid valve repair.
Acar et al. (1998) conducted a cohort in Double discordance (congenitally corrected transposition of the great arteries) with abnormal tricuspid valve (n=62). Surgical interventions (anatomical correction vs conventional surgery) vs. No surgery or alternative surgical approaches was evaluated on Tricuspid regurgitation and mortality. Anatomical correction restoring a systemic left ventricle improved tricuspid regurgitation with 11% mortality, whereas conventional surgery leaving the right ventricle in systemic position had 33% mortality.
