Does radiofrequency ablation improve symptoms and reverse cardiac dysfunction in a pediatric patient with tachycardia-induced cardiomyopathy?
Radiofrequency ablation is an effective treatment for tachycardia-induced cardiomyopathy secondary to focal atrial tachycardia in children, leading to complete reversal of cardiac dysfunction.
Song et al. (2026) conducted a case report in Tachycardia-induced cardiomyopathy secondary to persistent tachycardia (n=1). Radiofrequency ablation guided by three-dimensional electroanatomical mapping was evaluated on Clinical symptoms, recurrence of atrial tachycardia, and cardiac dimensions/function. Radiofrequency ablation successfully treated a pediatric case of tachycardia-induced cardiomyopathy, with no recurrence of atrial tachycardia and normalization of cardiac function at 8 months.
