Cross-sectional Survey of Nickel Allergy Management in the Context of Intracardiac Device Implantation

There was no consensus regarding the ability of patch testing to accurately determine allergic reactions within cardiac tissue. There was also no agreement on the criteria for patch testing in patients undergoing intracardiac implantation. However, most would inquire about a history of contact sensitivity to previously implanted devices. With a positive patch test, nickel-based intracardiac devices should be avoided, or the decision should be left to the discretion of the cardiologist.
