1/220. Pericardial heart disease: a study of its causes, consequences, and morphologic features.This report reviews morphologic aspects of pericardial heart disease. A morphologic classification for this condition is presented. An ideal classification of pericardial heart disease obviously would take into account clinical, etiologic and morphologic features of this condition but a single classification combining these three components is lacking. Pericardial heart disease is relatively uncommon clinically, and when present at necropsy it usually had not been recognized during life. The term "pericarditis" is inaccurate because most pericardial diseases are noninflammatory in nature. Morphologically chronic pericardial heart disease may present clinically as an acute illness. Even when clinical symptoms are present, however, few patients develop evidence of cardiac dysfunction (constriction). When pericardial constriction occurs, it is the result of increased pericardial fluid or increased pericardial tissue or both. Increased fluid is treated by drainage; increased tissue is treated by excision. In most patients with chronic constrictive pericarditis the etiology is not apparent even after histologic examination of pericardia.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
2/220. Purulent pericarditis misdiagnosed as septic shock.BACKGROUND: Septic shock is common, with approximately 200,000 cases recognized annually. This syndrome is so well characterized that when a patient is febrile and in shock, septic shock may be diagnosed without regard to alternative possibilities. Purulent pericarditis is a relatively rare disorder in which fever and hypotension are common. Classic signs and symptoms, such as chest pain, pericardial friction rub, pulsus paradoxus, and elevation of jugular venous pressure, are seen in only 50%. methods: In this report, we describe four patients in whom purulent pericarditis and pericardial tamponade was initially misdiagnosed as septic shock. During a 3-month period, three men and one woman (mean age, 44.5 years) came to Kern Medical Center with purulent pericarditis and pericardial tamponade. These cases represented 13% of patients admitted with a diagnosis of septic shock. RESULTS: All patients were bacteremic, and the classic findings of pericardial tamponade were absent or relatively subtle. Hemodynamic findings of elevated systemic vascular resistance, low cardiac output, and normal pulmonary artery occlusion pressure were critical to the diagnosis. CONCLUSIONS: Consideration of purulent pericarditis is important in cases diagnosed as septic shock. Clinicians should be aware that patients with purulent pericarditis may not exhibit classic signs and symptoms, and a high index of suspicion is necessary for appropriate management.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
3/220. Pericardial injury following severe sepsis from faecal peritonitis--a case report on the use of continuous cardiac output monitoring.We report on a case of a 43-year-old man who developed reversible myocardial depression and pericarditis related to severe sepsis secondary to rectosigmoid colonic perforation. The management of this patient was aided by the use of a continuous thermodilution cardiac output catheter and monitor, recently introduced in clinical practice.- - - - - - - - - - ranking = 5keywords = cardiac (Clic here for more details about this article) |
4/220. hypothyroidism presenting as acute cardiac tamponade with viral pericarditis.This report describes the case of a young woman who presented to an emergency department with severe abdominal pain and shock. The patient was found to have pericardial tamponade due to a massive pericardial effusion. On further evaluation, the etiology of this effusion was considered to be secondary to hypothyroidism with concominant acute viral pericarditis leading to a fulminant tamponade. The presentation, differential diagnosis, and management of pericardial effusion and tamponade secondary to hypothyroidism and viral pericarditis are discussed. The diagnosis of hypothyroidism in conjunction with acute viral pericarditis should be considered in patients presenting with unexplained pericardial effusion and tamponade.- - - - - - - - - - ranking = 4keywords = cardiac (Clic here for more details about this article) |
5/220. Acute myocardial infarction: a rare presentation of pancreatic carcinoma.Secondary neoplastic involvement of the heart is common but usually asymptomatic. Malignancy rarely presents as acute pericarditis, cardiac tamponade, and myocardial infarction in the same patient. We report a patient with unsuspected metastatic pancreatic adenocarcinoma who presented with acute pericarditis and cardiac tamponade and subsequently developed a myocardial infarction due to coronary artery occlusion secondary to a metastatic deposit around the left anterior descending artery.- - - - - - - - - - ranking = 2keywords = cardiac (Clic here for more details about this article) |
6/220. Primary right atrial angiosarcoma mimicking acute pericarditis, pulmonary embolism, and tricuspid stenosis.A 29 year old white man presented to the emergency room with new onset pleuritic chest pain and shortness of breath. He was initially diagnosed as having viral pericarditis and was treated with non-steroidal anti-inflammatory drugs. A few weeks later he developed recurrent chest pain with cough and haemoptysis. Chest radiography, cardiac examination, transthoracic and transoesophageal echocardiography pointed to a mass that arose from the posterior wall of the right atrium, not attached to the interatrial septum, which protruded into the lumen of the right atrium causing intermittent obstruction of inflow across the tricuspid valve. Contrast computed tomography of the chest showed a right atrial mass extending to the anterior chest wall. The lung fields were studded with numerous pulmonary nodules suggestive of metastases. A fine needle aspiration of the pulmonary nodule revealed histopathology consistent with spindle cell sarcoma thought to originate in the right atrium. Immunohistochemical stains confirmed that this was an angiosarcoma. There was no evidence of extracardiac origin of the tumour. The patient was treated with chemotherapy and radiation. This case highlights the clinical presentation, rapid and aggressive course of cardiac angiosarcomas, and the diagnostic modalities available for accurate diagnosis.- - - - - - - - - - ranking = 3keywords = cardiac (Clic here for more details about this article) |
7/220. Restrictive pericarditis.BACKGROUND: Pericardial thickening is an uncommon complication of cardiac surgery. OBJECTIVES: To study pericardial thickening as the cause of severe postoperative venous congestion. SUBJECTS: Two men, one with severe aortic stenosis and single coronary artery disease, and one with coronary artery disease after an old inferior infarction. Both had coronary artery bypass grafting surgery. methods: magnetic resonance imaging (MRI), Doppler echocardiography, and cardiac catheterisation. RESULTS: venous pressure was raised in both patients. MRI showed mildly thickened pericardium, and cardiac catheterisation indicated diastolic equalization of pressures in the four chambers. Jugular venous pulse showed a dominant "Y" descent coinciding with early diastolic flow in the superior vena cava, and mitral and tricuspid Doppler forward flow proved restrictive physiology. The clinical background suggested pericardial disease so both patients had pericardiectomy. This proved the pericardium to be thickened; the extent of fibrosis also involved the epicardium. CONCLUSIONS: Although rare, restrictive pericarditis (restrictive ventricular physiology resulting from pericardial disease) should be considered to be a separate diagnostic entity because its pathological basis and treatment are different from intrinsic myocardial disease. This diagnosis may be confirmed by standard investigational techniques or may require diagnostic thoracotomy.- - - - - - - - - - ranking = 3keywords = cardiac (Clic here for more details about this article) |
8/220. coxiella burnetii pericarditis: report of 15 cases and review.q fever is characterized by its clinical polymorphism, and pericarditis associated with q fever has occasionally been described. Herein we report 15 cases of coxiella burnetii pericarditis, 9 from our data bank and 6 encountered within the past 12 months. Three patients presented with life-threatening tamponade. We compare our cases with the 18 previously reported and with 60 q fever-matched controls at our center. This study showed that q fever pericarditis can present as acute as well as chronic disease; we describe relapse after 6 months in association with a serological profile compatible with the chronic form of disease (phase I C. burnetii IgG titer of > or = 800). Discriminant factors among patients and controls are age of > 52 years (adjusted odds ratio [OR], 5.66), the occurrence of general symptoms such as arthralgias or myalgias (adjusted OR, 6.54), and a normal erythrocyte sedimentation rate (adjusted OR, 16.37). No specific symptoms or underlying cardiac predispositions are observed.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
9/220. cardiac tamponade preceding adrenal insufficiency--an unusual presentation of Addison's disease: a report of two cases.Two cases of young healthy males presenting with cardiac tamponade and developing clinical adrenal insufficiency within a few weeks are described. On presentation they had a brisk inflammatory response with complement activation. Both had signs of subclinical hepatitis, and both have later shown evidence of thyroid involvement. The possibility of a connection between pericarditis and adrenal insufficiency is discussed.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
10/220. Non-surgical treatment of purulent pericarditis, due to non-encapsulated haemophilus influenzae, in an immunocompromised patient.A 59-year-old woman suffering from rheumatoid arthritis was admitted with pleural empyema and pericarditis due to non-encapsulated H. influenzae, and developed signs of cardiac tamponade. Purulent pericarditis resolved after ultrasound-guided percutaneous aspiration and systemic antimicrobial therapy. Serial echocardiographic examinations showed a slowly vanishing effusion. Long term follow-up revealed no evidence of pericardial constriction. This case illustrates that life-threatening purulent pericarditis in an immunocompromised patient may respond well to non-surgical treatment.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
