Tachycardia-induced cardiomyopathy secondary to right ventricular outflow tract ventricular tachycardia: Improvement of left ventricular systolic function after radiofrequency catheter ablation of the arrhythmia

Cardiomyopathy Secondary to RVOT VT. Introduction: Several reports describe development of cardiomyopathies secondary to supraventricular tachycardia, Few reports have described cardiomyopathies secondary to ventricular tachycardia. Methods and Results: We describe a patient who presented with dilated cardiomyopathy and repetitive nonsustained monomorphic ventricular tachycardia, Cardiac catheterization showed hemodynamically insignificant coronary artery disease, Radiofrequency ablation of a right ventricular outflow tract ventricular tachycardia resulted in improvement of the left ventricular systolic function and resolution of heart failure symptoms. Conclusions: This report suggests that right ventricular outflow tract ventricular tachycardia may cause reversible tachycardia-induced cardiomyopathy.
