A simple method for continuous pericardial drainage

Needle pericardiocentesis is performed routinely for relief of symptoms in patients with pericardial effusion and cardiac tamponade. In many patients however, reaccumulation of fluid requires further aspiration or surgical drainage, occasionally as a matter of urgency. Both procedures carry significant risks which may be avoided by insertion of an indwelling catheter. The Viggo subclavian cannula proves ideal for prolonged drainage of pericardial effusions and for relief of tamponade in an emergency situation. Introduction into the pericardium is simple, safe, and can be performed quickly without specialised equipment. This procedure is described and illustrated in patients with tuberculous and rheumatoid pericarditis.     

MR imaging of the pericardium

Imaging of the pericardium requires understanding of anatomy and the normal and abnormal physiology of the pericardium. MR imaging is well-suited for answering clinical questions regarding suspected pericardial disease. Pericardial diseases that may be effectively imaged with MR imaging include pericarditis, pericardial effusion, cardiac-pericardial tamponade, constrictive pericarditis, pericardial cysts, absence of the pericardium, and pericardial masses. Although benign and malignant primary tumors of the pericardium may be occasionally encountered, the most common etiology of a pericardial mass is metastatic disease.     

Pericarditis: inflammation or infarction?

Pericarditis occurs when there is inflammation of the pericardium, a 2-layer sac that surrounds the myocardium. These layers are separated by 15 to 20 mL of thin serous fluid. The accumulation of serous fluid along with the presence of inflammatory cells and fibrin can compromise cardiac function. The cause of pericarditis can be related to many disorders and often mimics signs of myocardial ischemia or acute myocardial infarction (AMI). Complications such as cardiac tamponade can occur with a large effusion and can be life threatening. It is essential to differentiate pericarditis from AMI. Preservation of heart muscle in AMI is essential as is proper treatment and prevention of complications such as cardiac tamponade, which can occur as a result of pericarditis. This article discusses the common causes, clinical manifestations, diagnostic procedures, and treatment associated with pericarditis.     

AMOEBIC PERICARDITIS

Twenty-five patients with amoebic pericarditis were studiedand the clinical findings described. Two types were recognized,one with a serous effusion associated with a left lobe liverabscess and the other with a purulent effusion resulting fromrupture of a liver abscess into the pericardium. These havebeen termed presuppurative and suppurative amoebic pericarditisrespectively. The first type may progress to the second. Five patients suffered from the presuppurative variety of pericarditisand all recovered following treatment of the liver abscess. Of the 20 patients with suppurative pericarditis 12 recoveredand had no residual disability. In the eight patients who succumbed,death was due to cardiac tamponade (usually when the correctdiagnosis had not been made) or to constrictive pericarditisin which surgery was unsuccessful. It appears from this series that if suppurative amoebio pericarditisis treated by pericardial aspiration to relieve tamponade, andby the anti-amoebic drugs emetine hydrochloride and chloroquine,a proportion of patients recover fully without developing constriction.When constrictive pericarditis develops, conservative treatmentshould be continued as resolution often occurs. Pericardectomyshould be reserved for cases in which death seems inevitableunless constriction is relieved. ² The Amoebiasis Research Unit is sponsored by the followingbodies: The South African Council for Scientific and IndustrialResearch, University of Natal, Natal Pro vincial Administration,United States Public Health Service (Grant E-1592).     

Chronic constrictive pericarditis induced by long-term bromocriptine therapy: report of two cases.

OBJECTIVE: To report two cases of chronic constrictive pericarditis that appear to be related to the intake of bromocriptine for Parkinson's disease. CASE SUMMARY: Two white men (aged 63 and 69 y) were treated with bromocriptine for four (40 mg/d) and two years (30 mg/d), respectively, with a cumulative dose intake of 58.4 and 21.9 g, respectively. The patients experienced dyspnea with bilateral lower-limb edema and pleural effusion, suggesting right cardiac dysfunction. Echocardiography, computed tomography, and cardiac catheterization results were compatible with a diagnosis of constrictive pericarditis, so pericardectomy was performed on both patients. The anatomic pathology examination showed a fibrous pericardium; cultures were sterile. In the first case, pleural effusion recurred seven months after the pericarditis; bromocriptine was suspected and treatment was discontinued. In the second case, just prior to the pericardectomy, an episode of mental confusion occurred and prompted the cessation of bromocriptine therapy. DISCUSSION: To the best of our knowledge, only one case of constrictive pericarditis induced by bromocriptine therapy has previously been described in the literature. CONCLUSIONS: Our cases call attention to a possible association between bromocriptine use in patients who have Parkinson's disease and constrictive pericarditis.     

Post-cardiac injury syndrome: an atypical case following percutaneous coronary intervention

Post-cardiac injury syndrome (PCIS) is a syndrome characterized by pericardial and/or pleural effusion, triggered by a cardiac injury, usually a myocardial infarction or cardiac surgery, rarely a minor cardiovascular percutaneous procedure. Nowadays, the post-cardiac injury syndrome, is regaining importance and interest as an emerging cause of pericarditis, especially in developed countries, due to a great and continuous increase in the number and complexity of percutaneous cardiologic procedures. The etiopathogenesis seems mediated by the immunitary system producing immune complexes, which deposit in the pericardium and pleura and trigger an inflammatory response. We present the atypical case of a 76-year-old man presenting with a hydro-pneumothorax, low-grade fever and elevated inflammation markers, after two complex percutaneous coronary interventions, executed 30 and 75 days prior. The clinical features of our case are consistent with the diagnostic criteria of PCIS: prior injury of the pericardium and/or myocardium, fever, leucocytosis, elevated inflammatory markers, remarkable steroid responsiveness and latency period. Only one element does not fit with this diagnosis and does not find any further explanation: the air accompanying the pleural effusion, determining a hydro-pneumothorax and requiring a pleural drainage catheter positioning.     

Acute pericarditis

Although acute pericarditis is most often associated with viral infection, it may also be caused by many diseases, drugs, invasive cardiothoracic procedures, and chest trauma. Diagnosing acute pericarditis is often a process of exclusion. A history of abrupt-onset chest pain, the presence of a pericardial friction rub, and changes on electrocardiography suggest acute pericarditis, as do PR-segment depression and upwardly concave ST-segment elevation. Although highly specific for pericarditis, the pericardial friction rub is often absent or transient. Auscultation during end expiration with the patient sitting up and leaning forward increases the likelihood of observing this physical finding. Echocardiography is recommended for most patients to confirm the diagnosis and to exclude tamponade. Outpatient management of select patients with acute pericarditis is an option. Complications may include pericardial effusion with tamponade, recurrence, and chronic constrictive pericarditis. Use of colchicine as an adjunct to conventional nonsteroidal anti-inflammatory drug therapy for acute viral pericarditis may hasten symptom resolution and reduce recurrences.     

Pericardial Disease: Diagnosis and Management

Pericardial diseases can present clinically as acute pericarditis, pericardial effusion, cardiac tamponade, and constrictive pericarditis. Patients can subsequently develop chronic or recurrent pericarditis. Structural abnormalities including congenitally absent pericardium and pericardial cysts are usually asymptomatic and are uncommon. Clinicians are often faced with several diagnostic and management questions relating to the various pericardial syndromes: What are the diagnostic criteria for the vast array of pericardial diseases? Which diagnostic tools should be used? Who requires hospitalization and who can be treated as an outpatient? Which medical management strategies have the best evidence base? When should corticosteroids be used? When should surgical pericardiectomy be considered? To identify relevant literature, we searched PubMed and MEDLINE using the keywords diagnosis, treatment, management, acute pericarditis, relapsing or recurrent pericarditis, pericardial effusion, cardiac tamponade, constrictive pericarditis, and restrictive cardiomyopathy. Studies were selected on the basis of clinical relevance and the impact on clinical practice. This review represents the currently available evidence and the experiences from the pericardial clinic at our institution to help guide the clinician in answering difficult diagnostic and management questions on pericardial diseases.CMR = cardiac magnetic resonance imaging; CT = computed tomography; CYP = cytochrome P450; ECG = electrocardiographic; ESC = European Society of Cardiology; IVC = inferior vena cava; LV = left ventricular; NSAID = nonsteroidal anti-inflammatory drug; RA = right atrium; RV = right ventricleThe pericardium is a thin covering that separates the heart from the remaining mediastinal structures and provides structural support while also having a substantial hemodynamic impact on the heart. The pericardium is not essential—normal cardiac function can be maintained in its absence—however, diseased pericardium presenting clinically as acute or chronic recurrent pericarditis, pericardial effusion, cardiac tamponade, and pericardial constriction can be challenging to manage and life-threatening in some cases. The etiology of pericardial disease is often difficult to determine or remains idiopathic. However, microorganisms, including viruses and bacteria; systemic illnesses, including neoplasia, autoimmune disease, and connective tissue disease; renal failure; previous cardiac surgery; previous myocardial infarction; trauma; aortic dissection; radiation; and, rarely, drugs have been associated with pericardial diseases.The diagnosis and management of pericardial diseases remain challenging because of the vast spectrum of manifestations and the lack of clinical data on which to base guidelines by the American College of Cardiology and the American Heart Association. However, the European Society of Cardiology (ESC) published guidelines on pericardial disease in 2004.¹ This review aims to describe the methods of diagnosing and managing major pericardial syndromes on the basis of the literature and the clinical experience of our pericardial clinic. Searches were performed on PubMed and MEDLINE using the keywords diagnosis, treatment, management, acute pericarditis, relapsing or recurrent pericarditis, pericardial effusion, cardiac tamponade, constrictive pericarditis, and restrictive cardiomyopathy. No date limitations were set. Studies were selected on the basis of clinical relevance and the impact on clinical practice.     

Diagnostic issues in the clinical management of pericarditis

Aims: To review the current major diagnostic issues on the diagnosis of acute and recurrent pericarditis. Methods: To review the current available evidence, we performed a through search of several evidence‐based sources of information, including Cochrane Database of Systematic Reviews, Clinical Evidence, Evidence‐based guidelines from National Guidelines Clearinghouse and a comprehensive Medline search with the MeSH terms ‘pericarditis’, ‘etiology’ and ‘diagnosis’. Results: The diagnosis of pericarditis is based on clinical criteria including symptoms, presence of specific physical findings (rubs), electrocardiographical changes and pericardial effusion. Although the aetiology may be varied, most cases are idiopathic or viral, even after an extensive diagnostic evaluation. In such cases, the course is often benign following anti‐inflammatory treatment, and management would be not affected by a more precise diagnostic evaluation. A triage of pericarditis can be safely performed on the basis of the clinical and echocardiographical presentation. Specific diagnostic tests are not warranted if no specific aetiologies are suspected on the basis of the epidemiological background, history and presentation. High‐risk features associated with specific aetiologies or complications include: fever > 38 °C, subacute onset, large pericardial effusion, cardiac tamponade, lack of response to aspirin or a NSAID. Conclusions: A targeted diagnostic evaluation is warranted in acute and recurrent pericarditis, with a specific aetiological search to rule out tuberculous, purulent or neoplastic pericarditis, as well as pericarditis related to a systemic disease, in selected patients according to the epidemiological background, presentation and clinical suspicion.     

Pericardial conditions: signs, symptoms and electrocardiogram changes.

This article describes the anatomy and physiology of the pericardium and the signs and symptoms of acute pericarditis, pericardial effusion and cardiac tamponade. It illustrates the likely electrocardiogram findings in each of these conditions and discusses how the results, combined with patient history and physical examination, can help emergency nurses make accurate diagnoses.     

Pericarditis: a probably overlooked complication of endoscopic variceal sclerotherapy

Two cases of acute pericarditis following endoscopic variceal sclerotherapy (EVS) that were resolved with conservative management are described. This complication arose respectively one and three days after EVS. The possible pathogenesis is the involvement of the pericardium in an inflammatory reaction that develops in the esophageal wall and surrounding tissues. Only five cases have been previously reported in the literature; the authors suppose that this fact may be due to the mild symptoms presented by the patients, which may result in underestimation of this complication. The technical details of EVS in the seven patients with pericarditis were analyzed, but no common etiologic factor was found. The authors strongly advise regular checks for clinical and instrumental signs of acute pericarditis after every session of EVS, so that appropriate management can be undertaken in an early phase and, if necessary, further EVS sessions delayed, in order to avoid cardiac tamponade or constrictive pericarditis.     

Cardiovascular magnetic resonance in pericardial diseases

The pericardium and pericardial diseases in particular have received, in contrast to other topics in the field of cardiology, relatively limited interest. Today, despite improved knowledge of pathophysiology of pericardial diseases and the availability of a wide spectrum of diagnostic tools, the diagnostic challenge remains. Not only the clinical presentation may be atypical, mimicking other cardiac, pulmonary or pleural diseases; in developed countries a shift for instance in the epidemiology of constrictive pericarditis has been noted. Accurate decision making is crucial taking into account the significant morbidity and mortality caused by complicated pericardial diseases, and the potential benefit of therapeutic interventions. Imaging herein has an important role, and cardiovascular magnetic resonance (CMR) is definitely one of the most versatile modalities to study the pericardium. It fuses excellent anatomic detail and tissue characterization with accurate evaluation of cardiac function and assessment of the haemodynamic consequences of pericardial constraint on cardiac filling. This review focuses on the current state of knowledge how CMR can be used to study the most common pericardial diseases.     

Spectrum of pericardial disease: part II

Pericardial disease is a common disorder seen in varying clinical settings, and may be the first manifestation of an underlying systemic disease. In part I, we focused on the current knowledge and management of the more common pericardial diseases: acute pericarditis, pericardial effusion, cardiac tamponade, chronic pericarditis and relapsing pericarditis. In part II, we will focus on the knowledge and management of pericardial involvement in chylous pericardial effusion cholesterol pericarditis, radiation pericarditis, pericardial involvement in systemic inflammatory diseases, autoreactive pericarditis, pericarditis in renal failure, pericardial constriction and effusive constrictive pericarditis.     

Usefulness of the transgastric view by transesophageal echocardiography in evaluating thickened pericardium in patients with constrictive pericarditis.

Detection of thickened pericardium in patients with constrictive pericarditis is essential for pericardiectomy because restrictive cardiomyopathy and severe tricuspid regurgitation show similar hemodynamic data. The purpose of this study was to clarify whether transesophageal echocardiography can evaluate thickened pericardium. We investigated 7 patients with constrictive pericarditis who underwent pericardiectomy. Thickened pericardium over the right atrium was detected in 6 patients, but the borders were not clear. Thickened pericardium over the left ventricle was not detected in any patients in the standard longitudinal and horizontal views. On the other hand, thickened pericardium over the ventricles was detected in all patients in the transgastric view as an echogenic area between the liver and ventricular wall. Tissue characteristics of the thickened pericardium could be evaluated because of the high-quality images in the transgastric view. The transgastric view by transesophageal echocardiography allows high-quality images of the pericardium, which might be useful in diagnosing constrictive pericarditis.

肺癌心脏转移21例临床治疗效果观察

1993年9月至1994年12月间我院共收治79例晚期肺癌患者，其中发现肺癌心脏转移21例。上述病例均经组织学、细胞学确诊。肺癌心脏转移早期，无典型心瓣股或心包病变的临床表现。临床上出现的症状多与转移癌在心脏受累的部位和范围有关，多数病人病情迅速恶化。由于肺癌心脏转移已属癌肿晚期，除积极支持和对症处理外，同时进行全身和局部化疗。大量心包积液出现心包填塞征象者给予心包穿刺放液，心包腔内注入地塞米松和倾钠等措施，个别病例则行心包切开引流术。本组15例病人平均存活期9个月，而未经治疗者一般仅能存活3个月。如何早期发现心脏转移癌和提高生存期，尚待进一步探索。     

Primary meningococcal pericarditis complicated by tamponade

Pericarditis as a complication of meningococcal meningitis or meningococcaemia is uncommon, occurring in approximately 5.1% of cases. Meningococcal infection of the pericardium in the absence of meningitis is even rarer, with only 22 cases previously described. We report a case of primary meningococcal pericarditis complicated by cardiac tamponade in a 27 year old male and review all previously reported cases. The clinical features, epidemiology, investigations and management of primary meningococcal pericarditis are discussed.     

Bacterial pericarditis caused by infected trichilemmal cyst

Bacterial pericarditis is a well-known although rare complication of Staphylococcus aureus infection in modern practice. We present a rare case of Staphylococcus pericarditis caused by an infected trichilemmal cyst present on patient’s scalp. Our case emphasizes that all cases of bacterial pericarditis should be thoroughly investigated for a source of infection. Constrictive changes can be seen in the pericardium postinfection, as in our patient, and should be treated aggressively. To our knowledge, a case of an infected cyst causing bacterial pericarditis has never been reported previously in the literature.     

Pericarditis mimicking Brugada syndrome

Introduction

Brugada syndrome (BrS) is a genetic heart disorder due to alteration of the ion channels function that causes an impaired in the cardiac conduction system. It is characterized by an abnormal electrocardiogram pattern and may be complicated by malignant ventricular arrhythmias.Pericarditis is an inflammation of the pericardium and 90% of isolated cases of acute pericarditis are idiopathic or viral. Acute pericarditis may appears with chest pain, fever, pericardial friction rub, and cardiac tamponade. Moreover, widespread ST segment changes occur due to involvement of the underlying epicardium.

MR imaging findings in 76 consecutive surgically proven cases of pericardial disease with CT and pathologic correlation

To describe findings of patients with surgically confirmed pericardial disease on state of the art MR sequences. Retrospective review was performed for patients who underwent pericardiectomy and preoperative MR over a 5 year period ending in 2009. Patients' records were reviewed to confirm the diagnosis of chronic recurrent pericarditis, constrictive pericarditis, or pericardial tumor. MR imaging findings of pericardial thickness, IVC diameter, presence or absence of pericardial or pleural effusion, pericardial edema, pericardial enhancement, and septal "bounce" were recorded. Patients with constriction had a larger IVC diameter (3.1 ± 0.4 cm) than patients with recurrent pain and no constriction (2.0 ± 0.4 cm). Mean pericardial thickness for the 16 patients with chronic recurrent pericarditis but no evidence of constriction was 4.8 ± 2.9 mm. Mean pericardial thickness for patients with constriction was 9.2 ± 7.0 cm with calcification, and 4.6 ± 2.1 cm without calcification. 94% of patients with chronic recurrent pericarditis had gadolinium enhancement of the pericardium, while 76% of patients with constriction had pericardial enhancement. Septal "bounce" was present in 19% of chronic recurrent pericarditis cases and 86% of constriction cases. 5 patients had a pericardial neoplasm, 1 of which was not identified preoperatively. State of the art MR techniques can identify significant and distinct findings in patients with chronic recurrent pericarditis, constrictive pericarditis, and pericardial tumors.
