Radiofrequency catheter ablation of the bundle branch reentrant ventricular tachycardia



Radiofrequency catheter ablation of the bundle branch reentrant ventricular tachycardia



Acta Medica Austriaca 28(1): 16-20



Bundle branch reentrant ventricular tachycardia (BBRVT) has a suitable anatomic substrate for radiofrequency catheter ablation. However, the experience with this treatment is still small. In the current study, we examined the safety and the long-term efficacy of radiofrequency ablation in the cure of patients with BBRVT. Four patients with BBRVT, identified during electrophysiological study, underwent temperature-controlled radiofrequency ablation of the right bundle branch (RBB). All of them had syncope and structural heart disease with reduced left ventricular ejection fraction. The baseline examination revealed an intraventricular block, prolonged HV interval and inducible sustained VT because of bundle branch reentry in all patients. RBB was successfully abolished in all patients after the delivery of 3 +- 1 radiofrequency pulses. After ablation, a permanent pacemaker was implanted in one patient with significantly prolonged HV interval. All patients were free of BBRVT during a mean follow-up of 20 months. One patient received implantable cardioverter-defibrillator for myocardial VT five months after ablation. Two patients developed congestive heart failure. Radiofrequency catheter ablation of the RBB is a safe and highly effective therapeutic procedure for definitive cure of BBRVT. Long-term prognosis of these patients depends mainly on the underlying heart disease and the treatment of other VT.
