Successful catheter cryoablation for premature ventricular contractions originating from the para‐Hisian region

Abstract

Abstract We achieved successful catheter cryoablation in a patient with para‐Hisian premature ventricular contractions (PVCs) without conduction disturbance using the freeze‐thaw‐freeze method while observing the atrial‐His bundle interval. Cryoablation could be considered an alternative to radiofrequency ablation for patients with para‐Hisian PVCs.
