Use of a circular mapping and ablation catheter for ablation of atypical right ventricular outflow tract arrhythmia.

ABSTRACT

A new technique for ablation of persistent ectopic activity with atypical electrocardiographic characteristics at the vicinity of the right ventricular outflow tract is described. A new circular mapping and ablation catheter initially designed for pulmonary vein ablation was used. Abolition of ectopic activity was achieved with minimal fluoroscopy and ablation times.
