Pacing Lead-Induced Granuloma in the Atrium : A Foreign Body Reaction to Polyurethane

الملخص EN

We described a case of an 82-year-old male who presented with a granuloma entrapping the polyurethane-coated pacing lead at the site of contact on the atrium.

He had been paced for 8 years without symptoms or signs suggestive of an allergic reaction to the pacemaker system and died from thrombosis of the superior mesenteric artery and heart failure.

A histological examination of the nodule showed an incidental granuloma with multinucleated giant cells.

No granuloma was found in the heart or the lung.
