Does transvenous catheter ablation of the right bundle branch prevent recurrence of ventricular tachycardia in a patient with bundle branch reentrant tachycardia?
Transvenous catheter ablation of the right bundle branch successfully eliminated recurrent, medically refractory bundle branch reentrant ventricular tachycardia with long-term efficacy.
Recurrent episodes of ventricular tachycardia not responding to medical treatment occurred in a 56-year-old man. Electrophysiological investigation showed ventricular tachycardia due to bundle branch reentry. Using a method similar to catheter ablation of the atrioventricular junction, ablation of the right bundle branch was performed by an electrical shock of 250 joules. While before the ablation ventricular tachycardia occurred several times a day and its induction by programmed ventricular stimulation was facilitated by the administration of antiarrhythmic drugs, no initiation of ventricular tachycardia was possible after ablation of the right bundle branch. Over a follow-up of 30 months the patient has not suffered from tachycardia and the right bundle branch block persists.
Volkmann et al. (Sun,) conducted a case report in Bundle branch reentrant ventricular tachycardia (n=1). Transvenous catheter ablation of the right bundle branch was evaluated on Recurrence of ventricular tachycardia. Transvenous catheter ablation of the right bundle branch successfully eliminated recurrent, medically refractory bundle branch reentrant ventricular tachycardia over a 30-month follow-up.
