1/91. Spontaneous pericardial hematoma in an infant.The finding of a pericardial hematoma is rare in the pediatric population. Its occurrence in an otherwise healthy 3-month-old infant is unprecedented in the literature. The hematoma was initially identified by echocardiography. Computerized tomography and magnetic resonance imaging did not contribute to the identification of the mass. An exploratory thoracotomy was necessary to rule out a neoplastic process. The final diagnosis of hemorrhagic pericarditis was made.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
2/91. Dramatic improvement of left ventricular function after cytotoxic therapy in lupus patients with acute cardiomyopathy: report of 6 cases.Although lupus cardiomyopathy is thought to be clinically uncommon, we encountered 6 patients with systemic lupus erythematosus (SLE) over a 10 year period who had severe left ventricular dysfunction and showed remarkable improvement in their cardiac function after cytotoxic therapy. All patients met the American College of rheumatology criteria for classification of SLE and presented with signs of severe biventricular failure relatively early in their disease. Concurrent manifestations of SLE at the time of cardiomyopathy included rash, arthritis, myalgias, pleuritis, pericarditis, and nephritis. Four of the 6 patients were taking prednisone 20 mg/day at the time heart failure developed. In all cases the CPK were normal. Evaluation of cardiac function by echocardiogram and/or radionuclide gated blood pool scintigraphy revealed a severe depression of ventricular function with initial left ventricular ejection fraction (LVEF) ranging from 11 to 34% (mean 19%). Within 6 months of initiation of cytotoxic treatment all patients showed a dramatic response: the post-treatment LVEF ranged from 25 to 55%. This series of patients suggests that cardiomyopathy may be a more common complication of SLE than previously reported. Cardiomyopathy occurs relatively early in the course of SLE, may lead to severe cardiac dysfunction despite corticosteroid therapy, and appears to be responsive to cytotoxic therapy.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
3/91. Non-Q wave acute myocardial infarction in acute meningococcemia in a 10-year-old girl.INTRODUCTION: Children with acute meningococcemia may have impaired myocardial function resulting in low cardiac output despite normal intravascular volume. Severe meningococcal infection has been associated with acute interstitial myocarditis, endocarditis, and pericarditis, but not with myocardial infarction. CASE: We present the case of a 10-year-old girl with positive family history for premature myocardial infarction who sustained an acute myocardial infarction temporally related to meningococcemia. DISCUSSION: This is the first pediatric case of non-Q wave acute myocardial infarction associated with purpura fulminans in meningococcemia. Similarly, the association of high troponin i levels and meningococcemia has not been described previously. Although, the patient's genetic predisposition for myocardial infarction might have been a potential contributing factor, there was no angiographic evidence of coronary artery disease in this patient. Thereby, other factors related to shock, endotoxin, microthrombi of meningococcemia, and their treatment might have been also contributing. We propose possible mechanisms for this rare but serious complication of meningococcemia and review the literature.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
4/91. Symptomatic pericarditis after influenza vaccination: report of two cases.The authors report two cases of benign acute pericarditis after the patients received vaccinations against influenza virus. The diagnoses were confirmed by serologic changes and by the findings of 12-lead electrocardiogram and echocardiography. Symptoms and clinical status improved on aspirin therapy. The authors underline the possible mechanisms of this rare complication of influenza vaccination.- - - - - - - - - - ranking = 5keywords = pericarditis (Clic here for more details about this article) |
5/91. Drug induced chest pain-rare but important.pericarditis, usually viral in origin, is an infrequent cause of chest pain. pericarditis due to drug allergy is even less frequent and is thus rarely considered in the differential diagnosis. A case is reported of a woman who presented with severe chest pain, caused by minocycline induced pericarditis. Such allergy may be more common than reported. It is suggested that drug induced pericarditis should be included in the differential diagnosis of acute chest pain.- - - - - - - - - - ranking = 2keywords = pericarditis (Clic here for more details about this article) |
6/91. Recurrent pericarditis after thoracic surgery.Acute pericarditis is a frequent complication after cardiac and/or thoracic surgery. Recurrent acute pericarditis with multiple episodes is an uncommon phenomenon, however. patients typically have chest pain and/or pericardial inflammation as shown by electrocardiography and echocardiography. Treatment presents a clinical challenge due to the condition's rarity and lack of multicenter comparative treatment studies. Numerous therapeutic modalities, including nonsteroidal anti-inflammatory agents (NSAIDs), corticosteroids, immunosuppressants, and pericardiectomy, have been used without overwhelming evidence of a standard protocol. We report a case in which 32 episodes of recurrent acute pericarditis occurred, emphasizing the need for multicenter trials comparing therapeutic modalities in the future.- - - - - - - - - - ranking = 7keywords = pericarditis (Clic here for more details about this article) |
7/91. 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) |
8/91. pancreatitis with electrocardiographic changes mimicking acute myocardial infarction.A 64-year-old woman with mild acute pancreatitis presented with epigastric pain, nausea and vomiting while undergoing hemodialysis for chronic renal insufficiency. Serial electrocardiograms revealed new onset ST segment elevations in leads V2 to V4 mimicking an anterior myocardial infarction, followed by diffusely inverted deep T waves. No cardiac pathology was demonstrated by echocardiography or coronary angiography. A review of the literature and possible pathophysiological mechanisms of electrocardiographic changes in acute pancreatitis, such as metabolic abnormalities, hemodynamic instability, vasopressors, pericarditis, myocarditis, a cardiobiliary reflex, exacerbation of underlying cardiac pathology, coagulopathy and coronary vasospasm, are discussed.- - - - - - - - - - ranking = 1keywords = pericarditis (Clic here for more details about this article) |
9/91. 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) |
10/91. Acute pericarditis with transient constriction.Transient constrictive pericarditis is a rare entity. It is characterized by clinical and echocardiographic features similar to constrictive pericarditis, but is distinguished by its transient nature. This feature is important to recognize for avoiding unnecessary pericardectomy. The case of a patient who presented with acute myopericarditis and typical echocardiographic features of constriction is described. Within weeks, all signs of constriction disappeared spontaneously.- - - - - - - - - - ranking = 7keywords = pericarditis (Clic here for more details about this article) |
