Key result
RF ablation reverses tachycardia-induced cardiomyopathy in an infant with SVT, allowing 8-month medication-free recovery.
Why the study?
Tachycardia-induced cardiomyopathy in infants with incessant supraventricular tachycardia refractory to medical treatment requires evaluation of reversibility after radiofrequency ablation.
Does transcatheter radiofrequency ablation improve symptoms in infants with tachycardia-induced cardiomyopathy due to medically refractory permanent junctional reciprocating tachycardia?
Does transcatheter radiofrequency ablation improve symptoms in infants with tachycardia-induced cardiomyopathy due to medically refractory permanent junctional reciprocating tachycardia?
Transcatheter radiofrequency ablation can successfully and safely treat tachycardia-induced cardiomyopathy in infants with medically refractory permanent junctional reciprocating tachycardia.

Supports ablation feasibility in refractory infant PJRT cardiomyopathy; leaves open need for larger pediatric studies.
Benito et al. (1995) studied this question. Radiofrequency ablation reversed tachycardia-induced cardiomyopathy in an infant with incessant supraventricular tachycardia, leaving the patient symptom-free without medication at 8 months.
