Delayed pericarditis associated with an implantable cardioverter defibrillator implantation using an active-fixation atrial lead.
A 57-year-old man with nonischemic dilated cardiomyopathy and ventricular tachycardia underwent routine dual chamber implantable cardioverter defibrillator (ICD) implantation. An active-fixation atrial lead was positioned at the lateral wall of the right atrium. He subsequently developed chronic severe pericarditis. Histopathological findings of the pericardium showed mechanical stimulus localized pericarditis. This case demonstrates that contact of the screw of the active-fixation atrial lead with the pericardium may be a possible mechanism for pericarditis after pacemaker/ICD implantation.
