Key result
Catheter ablation eliminates refractory atrial tachycardia and AF post-Mustard procedure without recurrence.
Why the study?
Does radiofrequency catheter ablation eliminate atrial tachyarrhythmias in a patient with univentricular heart and transposition of the great arteries after a Mustard operation?

Does radiofrequency catheter ablation eliminate atrial tachyarrhythmias in a patient with univentricular heart and transposition of the great arteries after a Mustard operation?
Radiofrequency catheter ablation using 3D mapping can successfully treat atrial tachyarrhythmias in patients with complex congenital heart disease post-Mustard operation.
May support ablation feasibility post-Mustard; leaves open efficacy in broader complex congenital heart disease populations.
A 31-year-old patient previously underwent a Mustard operation presented with palpitations. Atrial tachycardia and paroxysmal atrial fibrillation were documented on the surface electrocardiogram. Under the guidance of a three-dimensional electroanatomic mapping system, ablation of the isolated left-sided pulmonary vein and a cavo-tricuspid isthmus-dependent intra-atrial macro re-entry circuit eliminated atrial tachycardia and paroxysmal atrial fibrillation without the recurrence of atrial tachyarrhythmia.

Ban et al. (2014) conducted a case report in Atrial tachycardia and paroxysmal atrial fibrillation after Mustard operation (n=1). Radiofrequency catheter ablation was evaluated on Elimination of atrial tachycardia and paroxysmal atrial fibrillation without recurrence. Radiofrequency catheter ablation successfully eliminated atrial tachycardia and paroxysmal atrial fibrillation without recurrence in a patient with a previous Mustard operation.
