Tachycardia‐Induced Cardiomyopathy Secondary to Right Ventricular Outflow Tract Ventricular Tachycardia: Improvement of Left Ventricular Systolic Function After Radiofrequency Catheter Ablation of the Arrhythmia
Why the study?
Does radiofrequency catheter ablation improve left ventricular systolic function and resolve heart failure symptoms in a patient with tachycardia-induced cardiomyopathy secondary to right ventricular outflow tract ventricular tachycardia?

Implication
Supports ablation in select tachycardia-induced cardiomyopathy cases; leaves open broader applicability pending prospective data.
Structured PICO
Does radiofrequency catheter ablation improve left ventricular systolic function and resolve heart failure symptoms in a patient with tachycardia-induced cardiomyopathy secondary to right ventricular outflow tract ventricular tachycardia?
P
Population
A patient presenting with dilated cardiomyopathy and repetitive nonsustained monomorphic ventricular tachycardia (right ventricular outflow tract ventricular tachycardia) with hemodynamically insignificant coronary artery disease.
I
Intervention
Radiofrequency catheter ablation of the right ventricular outflow tract ventricular tachycardia.
O
Outcome
Improvement of left ventricular systolic function and resolution of heart failure symptoms.surrogate
Radiofrequency catheter ablation of right ventricular outflow tract ventricular tachycardia can reverse tachycardia-induced cardiomyopathy and resolve heart failure symptoms.
