1/73. The spectrum of dilated cardiomyopathy. The Johns Hopkins experience with 1,278 patients.This report describes the evaluation of 1,278 patients referred to The Johns Hopkins Hospital with dilated cardiomyopathy. After a careful history and physical examination, selected laboratory tests, and endomyocardial biopsy, a specific diagnosis was made in 49% of cases. In 16% of cases the biopsy demonstrated a specific histologic diagnosis. myocarditis and coronary artery disease were the most frequent specific diagnoses; 51% of patients were classified as idiopathic. Thus a rigorous and systematic search can demonstrate an underlying cause for approximately one-half of patients with unexplained cardiomyopathy. Endomyocardial biopsy plays a crucial role in this evaluation. Six cases are presented which demonstrate the utility of endomyocardial biopsy in specific clinical situations. In addition to its routine use in monitoring rejection in heart transplant recipients, endomyocardial biopsy is indicated in the evaluation of possible infiltrative cardiomyopathy, in differentiating restrictive cardiomyopathy from constrictive pericarditis, and in diagnosing and monitoring doxorubicin cardiotoxicity. The importance of diagnosing myocarditis remains controversial, and disagreement persists about the utility of immunosuppressive therapy in these patients. A combination of clinical and histologic features can divide patients with myocarditis into 4 subgroups--acute, fulminant, chronic active, and chronic persistent. This classification provides prognostic information and may identify those patients who may respond to immunosuppression, as well as those likely to have adverse outcomes from such treatment. The continued development of novel molecular techniques may allow endomyocardial biopsy to provide greater prognostic and therapeutic information in the future.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
2/73. myocarditis and pericarditis with tamponade associated with disseminated tuberculosis.Tuberculous involvement of the myocardium is relatively rare. Tuberculous pericarditis with tamponade and myocarditis in a young woman with no evidence of immunosuppression and disseminated tuberculosis is described. Three distinct forms of myocardial involvement are recognized: nodular tubercles (tuberculomas) of the myocardium; miliary tubercles of the myocardium; and an uncommon diffuse infiltrative type. The myocardium is involved by a hematogenous route, by lymphatic spread or contiguously from the pericardium. The diagnosis can be made by endomyocardial biopsy if clinical suspicion is strong and echocardiographic findings are suggestive. Antituberculosis drugs may be curative. With an increasing prevalence of tuberculosis, the possibility of potentially lethal myocardial tuberculosis is important to consider.- - - - - - - - - - ranking = 5keywords = pericarditis (Clic here for more details about this article) |
3/73. Reversible hyperthyroidism and cardiomyopathy caused by consumption of iodocasein.We report the case of a 52-year-old woman with recent diagnosis of acute myocarditis and pericarditis, admitted for fever, tachycardia, and dyspnea upon exertion. Hematochemical parameters and instrumental examinations suggested iatrogenic hyperthyroidism and secondary dilated cardiomyopathy. Although gathering information about the medication used at home was initially difficult because of the patient's refusal to cooperate, she ended up by disclosing the regular assumption of an iodocasein drug. A complete and stable regression of the clinical picture was reached by suspending the iodine derivative and using cardiovascular drugs.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
4/73. Myopericarditis caused by cyclophosphamide used to mobilize peripheral blood stem cells in a myeloma patient with renal failure.cyclophosphamide (CPA) is widely used for peripheral blood stem cell mobilization, and a dose adjustment of CPA in the presence of renal failure has not been suggested. However, we describe a myeloma patient with renal failure (serum creatinine 4.2 mg/dl, creatinine clearance 11.2 ml/min) receiving CPA 2 g/m2 for 2 days, who developed unexpectedly severe toxicity, including myopericarditis and prolonged myelosuppression. The serial serum concentrations of CPA metabolites were persistently much higher than those in a myeloma patient with normal renal function. We consider, therefore, that the dose of CPA should be reduced in the presence of severe renal failure when used as high-dose therapy or to mobilize peripheral blood stem cells.- - - - - - - - - - ranking = 5keywords = pericarditis (Clic here for more details about this article) |
5/73. Intrapericardial treatment of autoreactive myocarditis with triamcinolon. Successful administration in patients with minimal pericardial effusion.A major clinical drawback in the treatment of autoreactive pericarditis is its inherent feature to relapse. Intrapericardial treatment with triamcinolone was reported to be efficient in patients with large, symptomatic autoreactive pericardial effusions, avoiding side effects of systemic treatment as well as compliance problems. Intrapericardial treatment with 300 mg/m2 triamcinolone was for the first time performed in patients with autoreactive myopericarditis and minimal pericardial effusions (75 to 110 ml). After 12 months of follow-up both patients are asymptomatic and there were no further recurrences of pericardial effusion. pericardiocentesis in these patients was performed with the application of the PerDUCER device, guided by pericardioscopy. This device has a hemispherical cavity at the top of the instrument connected with a vacuum-producing syringe. In this cavity the pericardium is captured by vacuum and tangentially punctured by the introducer needle. pericardium that can be captured, must be up to 2 mm thin to fit into the hemispherical cavity. Pericardioscopy performed from the anterior mediastinum significantly contributed to the success of the procedures enabling visualization of the portions of the pericardium free of adipose tissue or adhesions, suitable for puncture with the PerDUCER. In conclusion, intrapericardial treatment of symptomatic autoreactive myopericarditis with minimal pericardial effusion was safely and efficiently performed in 2 patients. pericardiocentesis was enabled by means of the PerDUCER device, facilitated by pericardioscopy.- - - - - - - - - - ranking = 3keywords = pericarditis (Clic here for more details about this article) |
6/73. borrelia infection as a cause of carditis (a long-term study).BACKGROUND: Although the frequency of Lyme carditis is not high, it is one of the most challenging conditions in terms of diagnosis. No long-term studies that would help expand our body of knowledge concerning the circumstances of its development and the natural course of this form of Lyme borreliosis (LB), the most widespread anthropozoonosis in Central europe, have been reported to date. AIM: The authors sought to describe and assess the consequences of a less common form of Lyme carditis (LC). An assessment of the following aspects was made: a) the forms, natural history and sequelae of the less common clinical appearances of LC, b) the role of antibiotic therapy with reference to the late manifestations of LB. methods: Three patients were selected from a group of 60 consecutive patients with demonstrated LC during a follow-up period from 1987 to 2000. Patient no. 1 was being followed for myocarditis with frequent ventricular extrasystoles, patient no. 2 for pericarditis, and patient no. 3 for dilated cardiomyopathy as a late manifestation of LB. In addition to routine examination at entry, the patients were subjected to a standard 12-lead ECG, continuous 24-hour Holter ECG monitoring, exercise testing (bicycle ergometry), investigations of antibodies using ELISA and Western blot, investigation of thyroid (T3, T4, TSH tests) and mineral levels. RESULTS: The study showed no significant correlation between the clinical course and levels of specific antibodies. It confirmed the concept that inadequate or no therapy with antibiotics in the initial stage of the disease has a significant effect on the development of late sequelae. CONCLUSION: Based on the long-term treatment of three patients with less common, yet clinically urgent findings, the authors conclude that even a relatively serious clinical course is associated with no major limitations for affected individuals after an interval of several years.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
7/73. Acute myopericarditis after diphtheria, tetanus, and polio vaccination.We report the first case of myopericarditis after triple vaccination against diphtheria, tetanus, and poliovirus in a young adult. He presented with fever, acute chest pain, and diffuse ST-segment elevation 2 days after vaccination. Two-dimensional echocardiography findings were normal. Endomyocardial biopsy showed interstitial edema with diapedesis of erythrocytes. Laboratory findings showed inflammatory syndrome and elevated circulating immune complexes. He recovered within a few days with high-dose aspirin treatment and was without complications at 3-month follow-up. We discuss the different hypotheses for infective or hypersensitivity myocarditis.- - - - - - - - - - ranking = 5keywords = pericarditis (Clic here for more details about this article) |
8/73. Giant cell myocarditis, in a patient with Crohn's disease, treated with etanercept--a tumour necrosis factor-alpha antagonist.Cardiac disease in association with inflammatory bowel disease (IBD) is uncommon. Reports include pericarditis, pericardial effusion, myocarditis, myocardial infarction, endocarditis and arrythmias. Myocardial inflammation related to IBD may be due to a drug hypersensitivity reaction or micronutrient deficiency, or may be secondary to the underlying IBD as an extraintestinal manifestation. In this setting, myocarditis usually presents as congestive heart failure and/or refractory arrhythmia. prognosis varies among reported cases, including complete recovery, remission with recurrence and fatal disease. Treatment of myocarditis has included aminosalicylates and immunosuppressive medications. Recently, newer therapies for IBD have been developed, such as tumour necrosis factor-alpha (TNF-a) antagonists. The present report describes a case of a 46-year-old man with clinical and endoscopic evidence of moderately active colonic Crohn's disease who developed congestive heart failure due to giant cell myocarditis. Little clinical improvement occurred with immunosuppressive therapy. Only after the addition of etanercept, a TNF-a p75 receptor antagonist, did complete clinical resolution occur. These authors conclude that the use of TNF-a antagonists may be considered in the treatment of life-threatening extraintestinal manifestations of inflammatory bowel disease.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
9/73. Acute myocarditis in a patient with eosinophilia and pulmonary infiltrates.This is a case of nectrotising myopericarditis complicated with an acute apical left ventricular aneurysm in a young patient with the history of bronchial asthma and recurrent eosinophilia. Prompt clinical improvement coinciding with normalisation of the blood count in response to steroids was observed. Possible aetiology of hypereosinophilia is discussed.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
10/73. Left ventricular pseudoaneurysm after acute influenza A myocardiopericarditis.We describe the successful management of a rare case regarding an adult Caucasian who developed a left inferior ventricular pseudoaneurysm as a consequence of an influenza a virus infection of the upper respiratory tract followed by acute myocardiopericarditis. The cardiovascular features of this case illustrate the importance of raising a sufficient clinical index of suspicion for this common, but potentially lethal, entity.- - - - - - - - - - ranking = 5keywords = pericarditis (Clic here for more details about this article) |
