Does radiofrequency catheter ablation combined with atrial appendage resection effectively treat atrial tachycardia originating from the atrial appendage in children?
In children with atrial tachycardia originating from the atrial appendage and resulting in tachycardia-induced cardiomyopathy, atrial appendage resection is an effective treatment when radiofrequency catheter ablation fails.
Liu et al. (2022) conducted a case report in Atrial tachycardia originating from the atrial appendage (n=3). Radiofrequency catheter ablation and atrial appendage resection was evaluated on Cure or recurrence of atrial tachycardia. Radiofrequency catheter ablation combined with atrial appendage resection successfully treated atrial tachycardia and reversed cardiomyopathy in three children, with no recurrence at 1-18 months.
