Bipolar radiofrequency catheter ablation (RFCA) is a novel strategy for refractory or recurrent ventricular arrhythmias (VAs) resistant to conventional ablation methods. Lesions created during bipolar RFCA are larger than those created during sequential unipolar ablation. We present a case of refractory LV summit VAs, which identified the origin using a 2.7-F over-the-wire microelectrodes catheter, and it was successfully treated with bipolar RFCA in the acute phase.
Keywords: bipolar radiofrequency catheter ablation; over‐the‐wire microelectrodes catheter; ventricular premature contraction.
