The sequelae of Fontan-type repairs for functionally univentricular hearts include hemodynamic changes related to atrial enlargement and underlying anatomy, arrhythmias, and multiorgan system effects. Therapeutic interventions addressing both hemodynamic sequelae and arrhythmia substrates have been effective in improving quality of life and markedly reducing arrhythmia recurrence during midterm follow-up. Successful arrhythmia intervention requires careful assessment of the arrhythmia mechanisms and application of the appropriate surgical ablation techniques. The surgical intervention is challenging owing to redo sternotomy in univentricular physiology and anatomic variations. This chapter outlines the authors’ resternotomy and operative techniques for safe mediastinal reentry and the surgical and anatomic variants encountered in association with Fontan conversion.
