A case of effusive-constrictive pericarditis after cardiac surgery

A 60-year-old woman who had undergone repair of an atrial septal defect was readmitted to the hospital with dyspnea, abdominal distention, and leg edema 31 months after surgery. An echocardiogram demonstrated massive pericardial effusion. Cardiac catheterization revealed elevation and equilibrium of the 4-chamber diastolic pressure and a dip-and-plateau pattern in the right and the left ventricular pressures. Despite removal of pericardial fluid by pericardiocentesis, the findings and symptoms did not improve. The patient underwent both parietal and visceral pericardiectomy after which striking hemodynamic and symptomatic improvement occurred. Effusive-constrictive pericarditis is uncommon but should be considered in patients with refractory heart failure and massive pericardial effusion showing no improvement after removal of pericardial fluid.     

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.     

Diagnosing pericarditis

Pericarditis, or inflammation of the pericardium, is most often caused by viral infection. It can also develop as a result of bacterial or other infection, autoimmune disease, renal failure, injury to the mediastinal area, and the effects of certain drugs (notably hydralazine and procainamide). The clinical features of pericarditis depend on its cause, as well as the volume and type of effusion. Patients with uncomplicated pericarditis have pleuritic-type chest pain that radiates to the left shoulder and may be relieved by leaning forward. Chest radiographs, Doppler studies, and laboratory tests confirm the diagnosis and provide information about the degree of effusion. In most patients, pericarditis is mild and resolves spontaneously, although treatment with a nonsteroidal anti-inflammatory drug or a short course of a corticosteroid may be helpful. When a large pericardial effusion is produced, cardiac function may be compromised, and cardiac tamponade can occur. In patients with longstanding inflammation, the pericardium becomes fibrous or calcified, resulting in constriction of the heart. Drainage or surgical intervention may be necessary in patients with complicated pericarditis.     

Transitory effusive-constrictive pericarditis

Pericardial effusion of various sizes is a quite common clinical finding, while its progression to effusive-constrictive pericarditis occurs in about 1.4–14% of cases. Although available evidence on prevalence and prognosis of this rare pericardial syndrome is poor, apparently a considerable proportion of patients conservatively managed has a spontaneous resolution after several weeks.A 61-year-old female presented to our emergency department reporting fatigue, effort dyspnea and abdominal swelling. The echocardiography showed large pericardial effusion with initial hemodynamic impact, so she underwent a pericardiocentesis with drainage of 800–850 cm³ of exudative fluid, on which diagnostic investigations were undertaken: possible viral and bacterial infections, medical conditions, iatrogenic causes, neoplastic and connective tissue diseases were all excluded. Despite empirical therapy with NSAIDs and colchicine, after about one week she had a recurrence of pericardial effusion and progressive development of constriction. Echocardiography performed after a few weeks of anti-inflammatory therapy showed resolution of constriction and PE, with clinical improvement.If progression of pericardial syndromes to a constrictive form is rarely described in literature, cases of transitory effusive-constrictive phase are even more uncommon, mainly reported during the evolution of pericardial effusion. According to the available data, risk of progression to a constrictive form is very low in case of idiopathic pericardial effusion. We report a case of large idiopathic subacute pericardial effusion, treated with pericardiocentesis and then evolved into an effusive-constrictive pericarditis. A prolonged anti-inflammatory treatment leads to complete resolution of pericardial syndrome without necessity of pericardiectomy.     

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 infusion of tissue plasminogen activator in fibropurulent pericarditis

A 61-year-old man developed a loculated fibropurulent pericarditis, a rare complication of bacteremia. This occurred as a complication of a Staphylococcal aureus bacteremia from a head and neck abscess following self-extraction of a tooth. Despite surgical intervention and placement of 2 pericardial drains, a refractory, inadequately drained infected pericardial effusion persisted. Although there is limited experience with thrombolytic therapy to dissolve a fibrin clot in the pericardium, break down loculated adhesions, and facilitate free drainage of infected material, lysis is well described in the management of exudative pleural effusions. After infusion of 30 mg of tissue plasminogen activator in 100 cc normal saline through the pericardial drain of the patient, a large amount of infected serosanginous material subsequently drained during the next 2 days. The patient became afebrile and culture negative, remained hemodynamically stable, and had resolution of his pericarditis and pericardial effusion on electrocardiogram and echocardiogram, respectively.     

Polymicrobial bacterial pericarditis with mediastinitis after endotracheal intubation

Polymicrobial bacterial pericarditis with mediastinitis after traumatic endotracheal intubation is an unusual condition. We report a 54-year-old man, a victim of nasopharyngeal carcinoma, who developed pericardial effusion with tamponade after traumatic endotracheal intubation. The diagnosis of polymicrobial bacterial pericarditis was made when pericardiocentesis revealed purulent fluid that grew a mixed culture of anaerobic and aerobic bacteria, reflecting the normal upper airway flora. By bronchoscopic study, a laceration over the lower trachea was detected. The patient received prolonged aggressive antibiotic therapy and pericardial drainage. The infection improved, but the patient later died from another episode of nosocomial infection.     

Constrictive pericarditis complicating endovascular pacemaker implantation

A patient is described who has 6 months of progressive dyspnea and peripheral edema for 4 years following implantation of an endovascular pacemaker, which was complicated by a large hemorrhagic pericardial effusion. Evaluation was consistent with constrictive pericarditis, which is an extremely unusual complication of pacemaker implantation.     

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.     

Subacute effusive-constrictive pericarditis: diagnosis by serial echocardiography.

We report the case of a 30-year-old man with acute pericarditis in whom effusive-constrictive physiology developed rapidly in less than 2 weeks. Serial echocardiography demonstrated a dramatic change in the appearance of the pericardial effusion and the pericardial space. The patient underwent pericardiectomy with symptom relief. The findings at operation included a markedly thickened and inflamed pericardium. The case highlights the role of echocardiography in the evaluation of patients with pericardial disease and the echocardiographic features that prompted early surgical intervention.     

Haemophilus influenzae pericarditis with tamponade as the initial presentation of systemic lupus erythematosus

Although cardiac tamponade is an important and emergent complication of systemic lupus erythematosus (SLE), purulent pericarditis is rare despite the high frequency of pericardial effusion in SLE. We describe the first SLE case of Haemophilus influenzae type-f pericarditis with cardiac tamponade with SLE as the initial presentation. The pathophysiology and therapy are discussed.     

Clinical review: Intrapericardial fibrinolysis in management of purulent pericarditis

Purulent pericarditis (PP) is a potentially life-threatening disease. Reported mortality rates are between 20 and 30%. Constrictive pericarditis occurs over the course of PP in at least 3.5% of cases. The frequency of persistent PP (chronic or recurrent purulent pericardial effusion occurring despite drainage and adequate antibiotherapy) is unknown because this entity was not previously classified as a complication of PP. No consensus exists on the optimal management of PP. Nevertheless, the cornerstone of PP management is complete eradication of the focus of infection. In retrospective studies, compared to simple drainage, systematic pericardiectomy provided a prevention of constrictive pericarditis with better clinical outcome. Because of potential morbidity associated with pericardiectomy, intrapericardial fibrinolysis has been proposed as a less invasive method for prevention of persistent PP and constrictive pericarditis. Experimental data demonstrate that fibrin formation, which occurs during the first week of the disease, is an essential step in the evolution to constrictive pericarditis and persistent PP. We reviewed the literature using the MEDLINE database. We evaluated the clinical efficacy, outcome, and complications of pericardial fibrinolysis. Seventy-four cases of fibrinolysis in PP were analysed. Pericarditis of tuberculous origin were excluded. Among the 40 included cases, only two treated by late fibrinolysis encountered failure requiring pericardiectomy. No patient encountered clinical or echocardiographic features of constriction during follow-up. Only one serious complication was described. Despite the lack of definitive evidence, potential benefits of fibrinolysis as a less invasive alternative to surgery in the management of PP seem promising. Early consideration should be given to fibrinolysis in order to prevent both constrictive and persistent PP. Nevertheless, in case of failure of fibrinolysis, pericardiectomy remains the primary option for complete eradication of infection.     

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.     

A case of purulent pneumococcal pericarditis

Background

Purulent bacterial pericarditis is a rare and potentially fatal disease. The course may be fulminant, and the presentation may pose a diagnostic challenge.

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.     

Diagnosing tuberculous pericarditis

BACKGROUND: Definitive diagnosis of tuberculous pericarditis requires isolation of the tubercle bacillus from pericardial fluid, but isolating the organism is often difficult. AIM: To improve diagnostic efficiency for tuberculous pericarditis, using available tests. DESIGN: Prospective observational study. METHODS: Consecutive patients (n = 233) presenting with pericardial effusions underwent a predetermined diagnostic work-up. This included (i) clinical examination; (ii) pericardial fluid tests: biochemistry, microbiology, cytology, differential white blood cell (WBC) count, gamma interferon (IFN-gamma), adenosine deaminase (ADA) levels, polymerase chain reaction testing for Mycobacterium tuberculosis; (iii) HIV; (iv) sputum smear and culture; (v) blood biochemistry; and (vi) differential WBC count. A model was developed using 'classification and regression tree' analysis. The cut-off for the total diagnostic index (DI) was optimized using receiver operating characteristic (ROC) curves. RESULTS: Fever, night sweats, weight loss, serum globulin (>40 g/l) and peripheral blood leukocyte count (<10 x 10(9)/l) were independently predictive. The derived prediction model had 86% sensitivity and 84% specificity when applied to the study population. Pericardial fluid IFN-gamma >or=50 pg/ml, concentration had 92% sensitivity, 100% specificity and a positive predictive value (PPV) of 100% for the diagnosis of tuberculous pericarditis; pericardial fluid ADA >or=40 U/l had 87% sensitivity and 89% specificity. A diagnostic model including pericardial ADA, lymphocyte/neutrophil ratio, peripheral leukocyte count and HIV status had 96% sensitivity and 97% specificity; substituting pericardial IFN-gamma for ADA yielded 98% sensitivity and 100% specificity. DISCUSSION: Basic clinical and laboratory features can aid the diagnosis of tuberculous pericarditis. If available, pericardial IFN-gamma is the most useful diagnostic test. Otherwise we propose a prediction model that incorporates pericardial ADA and differential WBC counts.     

Management of tuberculous constrictive pericarditis and tuberculous pericardial effusion in Transkei: results at 10 years follow-up

BACKGROUND: Tuberculous pericarditis is common in Transkei (Eastern Cape). Two randomized trials showed benefits at two years for prednisolone in patients with constrictive pericarditis, and open drainage plus prednisolone in patients with pericardial effusion. AIM: To see whether the advantages of prednisolone and open drainage were maintained up to 10 years. DESIGN: Follow-up of randomized, double-blind, placebo-controlled trials. METHODS: All 383 patients (143 constriction, 240 effusion) received the same anti-tuberculosis chemotherapy. They were randomized to prednisolone or placebo for the first 11 weeks, and were followed-up over 10 years. Among the 240 with effusion, 122 were also randomized to immediate open surgical drainage of pericardial fluid versus pericardiocentesis as required. Adverse outcomes were: death from pericarditis, pericardiectomy, repeat pericardiocentesis, and subsequent open drainage. RESULTS: The 10-year follow-up rate was 96%. In constriction patients, adverse outcomes occurred in 19/70 (27%) prednisolone vs. 28/73 (38%) placebo (p = 0.15), deaths from pericarditis being 2 (3%) vs. 8 (11%), respectively (p = 0.098, Fisher's exact test). In effusion patients, adverse outcomes occurred in 14/27 (52%) with neither drainage nor prednisolone, vs. 4/29 (14%) drainage and prednisolone, 4/35 (11%) drainage and placebo, and 6/31 (19%) prednisolone and no drainage (p = 0.08 for interaction). Drainage eliminated the need for repeat pericardiocentesis. In the 176 with effusion and no drainage, adverse outcomes occurred in 17/88 (19%) prednisolone vs. 35/88 (40%) placebo patients (p = 0.003), with repeat pericardiocentesis 20 (23%) placebo vs. 9 (10%) prednisolone (p = 0.025). In a multivariate survival analysis (stratified by type of pericarditis), prednisolone reduced the overall death rate after adjusting for age and sex (p = 0.044), and substantially reduced the risk of death from pericarditis (p = 0.004). At 10 years, the great majority of surviving patients in all treatment groups were either fully active or out and about, even if activity was restricted. DISCUSSION: In the absence of a clear contraindication, a corticosteroid should be used in addition to antituberculosis chemotherapy in the management of patients with tuberculous pericarditis.     

Acute pericarditis complicated with pericardial effusion as first presentation of COVID‐19 in an adult sudanese patient: A case report

Acute pericarditis is an uncommon presentation of COVID‐19. Here, we described a case of a 50‐year‐old male patient who presented with chest pain without fever or cough and diagnosed with acute pericarditis complicated by pericardial effusion due to COVID‐19 after exclusion of other causes and received supportive treatment and improved over two weeks.     

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.     

Adjuvant corticosteroids for tuberculous pericarditis: promising,but not proven

BACKGROUND: There is controversy regarding the effectiveness of corticosteroids in tuberculous pericarditis, particularly in patients who are immunocompromised by HIV. AIM: To determine the effectiveness of adjuvant corticosteroids in tuberculous pericarditis. DESIGN: Systematic review of randomized controlled trials. METHODS: We searched the Cochrane Infectious Diseases Group trials register (June 2002), the Cochrane Controlled Trials Register (Issue 2, 2002), MEDLINE (January 1966 to March 2003), EMBASE (1980 to May 2002), and the reference lists of existing reviews, for randomized and quasi-randomized controlled trials of adjuvant corticosteroids in the treatment of suspected tuberculous pericarditis. We also contacted organizations and individuals working in the field. Two reviewers independently assessed trial quality and extracted data. We used meta-analysis with a fixed effects model to calculate the summary statistics, provided there was no statistically significant heterogeneity, and expressed results as relative risk. RESULTS: Four trials with a total of 469 participants met our criteria. Three (total n = 411) tested adjuvant steroids in participants with suspected tuberculous pericarditis in the pre-HIV era. Fewer participants died in the intervention group, but the potentially large reduction in mortality was not statistically significant (relative risk RR 0.65, 95%CI 0.36-1.16, n = 350; p = 0.14). One trial with 58 patients that enrolled HIV-positive individuals also showed a promising but non-significant trend on mortality (RR 0.50, 95%CI 0.19-1.28; p = 0.15). There was no significant beneficial effect of steroids on re-accumulation of pericardial effusion or progression to constrictive pericarditis. Patients with pericardial effusion were significantly more likely to be alive with no functional impairment at 2 years following treatment. However, the effect was not sustained in a sensitivity analysis that included patients who were lost to follow-up. DISCUSSION: Steroids could have large beneficial effects on mortality and morbidity in tuberculous pericarditis, but published trials are too small to be conclusive. Large placebo-controlled trials are required, and should include sufficient numbers of HIV-positive and HIV-negative participants, and an adequate adjuvant steroid dose.
