RecruitingDevice studyTorque Device EvaluationThis study will evaluate the safety and efficacy of a novel catheter torque device after the completion of a clinically-indicated electrophysiology study and/or ablation procedure in a pediatric patient. All electrophysiology studies and/or ablation procedures will be performed at the discretion of their primary cardiologist and will not be affected by this study protocol. The study protocol will commence once the attending electrophysiologist has completed all necessary intervention and testing and no further evaluation is required.
