Key result
Ablation or antiarrhythmic therapy is linked to complete ventricular recovery in 100% of pediatric TIC.
Why the study?
Tachycardia-induced cardiomyopathy is a rare and treatable cause of heart failure in children, but clinical data on its management and outcomes are limited.
Does arrhythmia control via catheter ablation or antiarrhythmic drugs improve ventricular function in children with tachycardia-induced cardiomyopathy?
Population
10 children with tachycardia-induced cardiomyopathy, median age 12 years
Comparison
Catheter ablation vs antiarrhythmic drugs
Design
Retrospective case series from a single Pediatric Cardiology Clinic

Does arrhythmia control via catheter ablation or antiarrhythmic drugs improve ventricular function in children with tachycardia-induced cardiomyopathy?
Tachycardia-induced cardiomyopathy in children is a reversible cause of heart failure that responds well to aggressive arrhythmia control via ablation or medical therapy.
Arslan et al. (2019) conducted an observational in Tachycardia-induced cardiomyopathy (n=10). Catheter ablation or antiarrhythmic drugs was evaluated on Complete recovery of ventricular function. Treatment of tachycardia-induced cardiomyopathy with catheter ablation or antiarrhythmic drugs led to complete recovery of ventricular function in all 10 children.
