WebIntroduction: Standard unipolar radiofrequency ablation (RFA) is typically successful in eliminating premature ventricular contractions (PVCs) originating from the ventricular outflow tract region. In a minority of cases, this approach may be ineffective. We report 4 cases where bipolar RFA was attempted after failed unipolar RFA.
