Background: There have not been previous reports of patients undergoing percutaneous coronary intervention (PCI) using a gadolinium chelate.
Methods and results: A 74-year-old woman, who had a history of anaphylactic shock 4 times in response to iodinated contrast media despite preprocedural intravenous administration of hydrocortisone, was hospitalized because of unstable angina refractory to intensive medical treatment. Fully considering the risks of iodinated agents, digital subtraction coronary angiography and PCI were performed using gadopentetate dimeglumine without any side effects or complications.
Conclusions: Gadolinium chelates can be an alternative contrast media during PCI in particular patients with contraindications to iodinated media.
