Key result
Catheter ablation successfully treated nine different consecutive atrial tachyarrhythmias in a single Fontan patient over a 6-year period, demonstrating different underlying mechanisms.
Case Report (n=1)
In a Fontan patient, successive atrial tachyarrhythmias can be caused by different mechanisms, likely due to progressive atrial cardiomyopathy, and can be treated by catheter ablation.

Serial ablation may be feasible for recurrent arrhythmias in Fontan patients; leaves open whether progressive remodeling drives mechanism shifts.
INTRODUCTION: Atrial tachyarrhythmias (AT) frequently develop later after a Fontan operation and can be successfully treated by ablative therapy. However, new arrhythmias often develop. METHODS AND RESULTS: Consecutive AT emerging in a Fontan patient were ablated using three-dimensional electro-anatomical mapping. During a 6-year period, nine different AT were ablated, including intraatrial reentrant AT (N=5), focal AT (N=3), and focal atrial fibrillation (N=1) originating from distinct right atrial sites. CONCLUSION: In a Fontan patient, successive AT can be caused by different mechanisms. These AT are most likely the result of progressive atrial cardiomyopathy and can be treated by catheter ablation.

Groot et al. (2009) conducted a case report in Postoperative Atrial Tachyarrhythmias in a Fontan Patient (n=1). Catheter ablation using three-dimensional electro-anatomical mapping was evaluated on Ablation of consecutive atrial tachyarrhythmias. Catheter ablation successfully treated nine different consecutive atrial tachyarrhythmias in a single Fontan patient over a 6-year period, demonstrating different underlying mechanisms.
