Complete heart block due to granulomatous giant cell myocarditis: report of 3 cases.
3 patients with chronic complete AV block were found at autopsy to have granulomatous giant cell myocarditis (GGCM). In 1 patient an unusual clinical course led to more extensive investigation including echocardiography which revealed ventricular septal abnormalities. A review of the literature is presented. Although GGCM is a rare disease echocardiography may be a useful screening procedure in patient with AV block especially in the presence of immunological disorders.
