Cardiac manifestations of Wegener's granulomatosis: Case report and review of the literature

Wegener's granulomatosis, first characterized as a clinical syndrome in 1936, is a rare form of vasculitis of the small- and medium-sized blood vessels affecting mainly the upper and lower respiratory tracts as well as the kidneys. This review article describes the case of a 45-year-old man who developed aortic regurgitation and third degree heart block secondary to Wegener's granulomatosis. He subsequently presented to our institution 3 years later with pulmonary hemorrhage. The ensuing literature review reveals that historically clinical cardiac involvement in Wegener's has been rare, particularly with valvular lesions. However, recent literature has shown an increase in reported cases of cardiac valvular lesions in Wegener's. The presented case report along with recently reported case reports highlight the morbidity and mortality associated with such cardiac lesions. We believe routine cardiovascular supervision including echocardiography and electrocardiograms are important for the screening and monitoring of patients with Wegener's granulomatosis.
