Catheter ablation in patients with pleomorphic, idiopathic, premature ventricular complexes

The presence of pleomorphic PVCs affects ablation outcomes. Successful elimination of the predominant PVC often results in successful ablation, even if not all PVCs are targeted. Although pleomorphic PVCs infrequently require repeat ablation procedures, most recurrences are due to reemergence of the originally targeted predominant PVC morphology.
