Why the study?
Does low energy catheter ablation prevent recurrence of right ventricular outflow tract tachycardia in a patient intolerant to antiarrhythmic medication?
Does low energy catheter ablation prevent recurrence of right ventricular outflow tract tachycardia in a patient intolerant to antiarrhythmic medication?
Low energy catheter ablation successfully prevented recurrence of right ventricular outflow tract tachycardia in a patient intolerant to antiarrhythmic medication over a 7-month follow-up.
May support low-energy ablation for RVOT VT in antiarrhythmic-intolerant patients; hypothesis-generating from single case.
A 38 year old woman with a structurally normal heart presented with near syncope and had right ventricular outflow tract tachycardia. She was intolerant of antiarrhythmic medication and underwent low energy catheter ablation. Six non-arcing shocks of 25 J were delivered to the right ventricular outflow tract. No further ventricular tachycardia occurred during a follow up of seven months without antiarrhythmic treatment.
