Cardiac involvement in haemochromatosis includes development of
congestive heart failure
and/or cardiac arrhythmias. To elucidate the importance of this disorder among patients with severe cardiac bradyarrhythmias necessitating treatment with a permanent pacemaker, such patients were screened for evidence of iron overload. Serum ferritin was determined in 232 men treated with a permanent pacemaker. In six patients (2.6%) the serum ferritin values were twice the upper normal limit. In three of these, causes other than iron overload were found (
liver cancer
, myeloma and amiodarone treatment), while in three (1.3%) iron overload was suspected. All the latter three had atrioventricular block of second to third degree. In these patients percutaneous liver biopsy was performed. The specimens were examined by light and electron microscopy and the iron content was determined by atomic absorption spectrophotometry. The results of these investigations showed iron overload in the liver. The prevalence of iron overload (2.0%) among this male pacemaker-treated population with AV block II-III is significantly higher than the rates previously found in urban populations in Sweden. The present data indicate that screening for haemochromatosis is of importance among males with second and third degree atrioventricular-block of unknown etiology.

Hereditary hemochromatosis is an autosomal recessive disorder, the gene for which occurs in approximately 10% of Americans, most of whom are unaffected heterozygotes. Approximately 5/1000 white Americans are homozygous and at risk of developing severe and potentially lethal hemochromatosis. The disorder affects numerous organ systems, but the most common symptoms are fatigue, palpitations, joint pains, and impotence; the most common signs are those that relate to hypothalamic, cardiac, hepatic or pancreatic dysfunction, including poor cold tolerance, impotence in males, amenorrhea in females, cardiac arrhythmias, dyspnea, edema, hepatosplenomegaly, spider telangiectases, ascites, deformity, swelling or limitation of motion of joints, weight loss, hyperpigmentation. Characteristic abnormalities of laboratory tests include elevated serum iron concentration, high transferrin saturation, elevated serum ferritin concentration, elevated serum transaminases, hyperglycemia and low values for thyroid-stimulating hormone (TSH) and gonadotropins. Death may be the result of cardiac arrhythmia,
congestive heart failure
, liver failure or
liver cancer
. Since many of these complications cannot be reversed once they have developed, early diagnosis and treatment are essential. In view of the high prevalence in the American population (prevalence varies with ethnic background), the low cost of diagnosis and treatment, the efficacy of treatment if begun early, and, on the other hand, high costs and low success rate of late diagnosis and treatment, systematic screening for hemochromatosis is warranted for all persons over the age of 20 years. The initial screening should be by measurement of serum iron concentration and transferrin saturation. The practice guideline provides a diagnostic algorithm for cases in which the serum transferrin saturation is 60% or greater. It also provides guidelines for clinical management.

Hepatic angiosarcoma is a rare form of
liver cancer
. The history, physical examination, and liver biopsy are nonspecific. As a result, diagnosis of angiosarcoma can be challenging. We report the case of an elderly woman with
congestive heart failure
caused by a hepatic angiosarcoma. The massive tumor burden created extensive arteriovenous shunting and a high-cardiac-output state.

This report describes the long-term (23 years) follow-up of a pediatric patient with acute lymphoblastic leukemia and eosinophilia who underwent multiple valve replacements. An 8-year-old boy with this complex disease was admitted in January 1984 and treated with 6-week course of vincristine, L-asparaginase, and prednisolone, which induced complete remission. He developed atrioventricular valvular insufficiency and infectious endocarditis at 13.5 and 17.3 years of ages, respectively, with progressive development of
congestive heart failure
. At 18.6 years of age, he underwent prosthetic valve replacement of both atrioventricular valves; the mitral valve was replaced with a mechanical prosthetic valve and tricuspid valve with a bioprosthetic valve. Histopathological examination of the ventricular endomyocardium showed extensive fibrous degeneration and persistent infiltration of eosinophils and lymphocytes. The right-side prosthesis was replaced twice, at 22.4 and 29 years of ages, due to degeneration of bioleaflets and thrombosis of the mechanical valve, respectively. Although he tolerated all surgical procedures, he developed
liver cancer
at 31 years of age and died. Autopsy could not be performed. The present study indicates that a subset of patients in complete remission of acute lymphoblastic leukemia and eosinophilia can show persistent myocardial eosinophilic infiltration and are at risk of late cardiac disease.
