Intermediate-Term Outcome of 140 Consecutive Fontan Conversions With Arrhythmia Operations

Atrial arrhythmias and progressive circulatory failure frequently develop in patients with a Fontan circulation. Improvement of flow dynamics and revision of the arrhythmia substrate may improve outcomes in selected patients. We sought to determine intermediate-term outcomes after Fontan conversion with arrhythmia operations and identify characteristics associated with decreased transplant-free survival.The first 140 Fontan conversions with...
