Unveiling the Intrusion: An Emergent Journey Into Tuberculous Pericarditis.

We present an interesting case of mycobacterial tuberculosis pericarditis presenting as effusive constrictive pericarditis with early cardiac tamponade in a young Mexican migrant of Haitian descent. The patient underwent a pericardial window and was treated with rifampin, isoniazid, pyrazinamide, ethambutol, and vitamin B6. After further receiving steroids, the patient was doing well and was discharged home safely.

The efficacy of colchicine in preventing atrial fibrillation recurrence and pericarditis post-catheter ablation for atrial fibrillation - A systematic review and meta-analysis of prospective studies.

Introduction: Catheter ablation (CA) initiates a proinflammatory process responsible for atrial fibrillation (AF) recurrence (25-40%) and pericarditis (0.8%). Due to its anti-inflammatory properties, colchicine, a microtubule inhibitor, is explored for the prevention of early AF recurrence and pericarditis after pulmonary vein isolation. We performed a pooled analysis to determine the rates of AF recurrence and pericarditis after CA in patients receiving colchicine. Methods: A comprehensive literature review was conducted on PubMed and SCOPUS from inception to December 2023 using medical subject headings and keywords, followed by a citation and reference search. We identified prospective studies reporting recurrent AF and pericarditis outcomes after catheter ablation in patients taking colchicine versus placebo. A binary random effects model was used to estimate pooled odds ratios and 95% confidence intervals. Sensitivity analysis was conducted using the leave-one-out method, and heterogeneity was assessed using the I2 statistic. Results: Of the 958 identified studies, 4 met our inclusion criteria. A total of 1,619 patients were analyzed; 743 received colchicine, and 875 were in the placebo group. Recurrent AF after CA occurred in 192 (29.0 %) of the colchicine group and 318 (39.5 %) of the placebo group. Post-ablation pericarditis occurred in 34 (5.3 %) of the colchicine group and 128 (16.5 %) of the placebo group. Pooled analysis of prospective studies showed that colchicine decreased the odds of recurrent AF [OR: 0.63 (95 % CI: 0.50-0.78), p < 0.01, I2  = 8 %] and post-ablation pericarditis [OR: 0.34 (95 % CI: 0.16-0.75), p < 0.01, I2  = 57 %]. Odds of GI disturbance were increased with colchicine use in our analysis [OR: 2.77 (95 % CI: 1.17-6.56), p = 0.02, I2  = 84 %]. Conclusion: Colchicine use is associated with decreased odds of recurrent AF and pericarditis post-CA from the analysis of prospective studies. These results underscore the potential for colchicine therapy for future exploration with randomized and controlled research with different dosages.

An Armored Heart: A Diagnosis Hidden in Plain Sight.

We report a case of an overtly symptomatic patient with delayed diagnosis of massive (>25-mm thickness), circular, constrictive pericarditis. Our patient underwent a successful surgical pericardiectomy-a high-risk procedure-revealing an armored heart, with an impressive clinical improvement. Diagnosis of constrictive pericarditis is challenging and requires high clinical suspicion.

D-Dimer and procalcitonin in patients with recurrent pericarditis: a prospective study.

Recurrent pericarditis, an inflammatory syndrome with a pathogenesis not fully elucidated, often presents diagnostic challenges. This study aims to assess the correlation of D-Dimer (D-D) and procalcitonin (PCT) levels with clinical, laboratory and imaging features in recurrent idiopathic pericarditis. We analyzed 412 patients with idiopathic recurrent pericarditis from 2019 to 2023 in our referral center. D-D and PCT values were obtained from emergency room in other Italian facilities. Among the cohort, PCT levels were assessed in 50 of 412 patients (12.1%), with only 4 showing marginal elevation. D-D levels were measured in 48 of 412 patients (11.6%), with 33 of them exhibiting elevated values. None of these patients had venous thromboembolism, and elevated D-D levels were significantly associated with pleural effusion, fever, higher CRP, increased white blood cell counts, higher neutrophil counts, reduced relative lymphocyte counts. Multivariate analysis revealed fever as the sole correlate of elevated D-D. PCT elevation was infrequent and unrelated to any variables. In idiopathic recurrent pericarditis unrelated to specific conditions, we observed a close association between elevated D-D levels and non-specific inflammation markers, including fever, increased CRP, and neutrophil leukocytosis. PCT levels were typically normal or mildly elevated.

SARS-CoV-2 mRNA vaccine-related myocarditis and pericarditis: An analysis of the Japanese Adverse Drug Event Report database.

BACKGROUND: The association between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccines and myocarditis/pericarditis in the Japanese population has not been systematically investigated. This study was aimed at clarifying the association between SARS-CoV-2 mRNA vaccines (BNT162b2 and mRNA-1273) and myocarditis/pericarditis as well as influencing factors by using the Japanese Adverse Drug Event Report database. METHODS: Reporting odds ratios (RORs) and 95 % confidence intervals (95 % CIs) for the association between the vaccines and myocarditis/pericarditis were calculated using data from the database (April 2004-December 2023). Age, sex, onset time, and outcomes in symptomatic patients were evaluated. RESULTS: The total number of reports was 880,999 (myocarditis: 1846; pericarditis: 761). The adverse events associated with the vaccines included myocarditis (919 cases) and pericarditis (321 cases), with the ROR [95 % CIs] being significant for both (myocarditis: 30.51 [27.82-33.45], pericarditis: 21.99 [19.03-25.40]). Furthermore, the ROR [95 % CIs] of BNT162b2 and mRNA-1273 were 15.64 [14.15-17.28] and 54.23 [48.13-61.10], respectively, for myocarditis, and 15.78 [13.52-18.42] and 27.03 [21.58-33.87], respectively, for pericarditis. Furthermore, most cases were ≤30 years or male. The period from vaccination to onset was ≤8 days, corresponding to early failure type based on analysis using the Weibull distribution. Outcomes were recovery or remission for most cases; however, they were severe or caused death in some cases. CONCLUSION: In the Japanese population, SARS-CoV-2 mRNA vaccination was significantly associated with the onset of myocarditis/pericarditis. The influencing factors included age of ≤30 years and male. Furthermore, although most adverse events occurred early after vaccination, overall outcomes were good.

A failing right heart in an eggshell: A case report of idiopathic constrictive pericarditis.

key Clinical Message: Constrictive Pericarditis is a rare fibrotic conversion of the pericardium that results in non-specific clinical symptoms such as hepatomegaly, ascites, pleural effusions, and lower extremity edema. A multi-modal diagnostic approach with cardiac imaging tools, cardiac hemodynamic measurements, and tissue biopsy can be used to diagnose Constrictive Pericarditis. Abstract: Constrictive Pericarditis is a rare complication resulting in the fibrotic conversion of the pericardium secondary to idiopathic, infective, post-surgical, or post-radiation etiologies. The rigid and restrictive nature of the pericardium can result in non-specific symptoms of volume overload that can mimic liver cirrhosis or congestive heart failure. We present the case of a 73-year-old female with constrictive pericarditis who presented with vague symptoms of abdominal pain, abdominal bloating, and bilateral lower extremity edema. This case report highlights the clinical manifestation, invasive, and non-invasive diagnostic work-up, and management of constrictive pericarditis.

Constrictive pericarditis in a patient with fiberglass lung disease: a case report.

BACKGROUND: Fiberglass has a larger aerodynamic diameter and is less likely to be inhaled into the lungs. Further, it will be cleared even if it is mechanically broken into smaller pieces and inhaled into the lungs. Fiberglass lung disease has been well documented if long term exposure but was thought reversible and would not cause severe diseases. The diagnosis of fiberglass lung disease depends on exposure history and histopathological findings. However, the exact occupational exposure history is often difficult to identify because mixed substance exposure often occurs and fiberglass disease is not as well-known as asbestosis. CASE PRESENTATION: A 66-year-old man had unexplained transudative pericardial effusion requiring pleural pericardial window operation twice at another medical center where asbestosis was told because of his self-reported long-term asbestosis exposure and the histopathological finding of a ferruginous body in his lung. Constrictive pericarditis developed two years later and resulted in congestive heart failure. Radical pericardiectomy combined with lung biopsy was performed following chest computed tomography imaging and the transudative nature of pericardial effusion not compatible with asbestosis. However, the histopathologic findings of his lung and pericardium at our hospital only showed chronic fibrosis without any asbestosis body. The patient's lung was found to be extremely fragile during a lung biopsy; histopathologic specimens were reviewed, and various fragments of fiberglass were found in the lung and pericardium. The patient's occupational exposure was carefully reevaluated, and he restated that he was only exposed to asbestosis for 1-2 years but was heavily exposed to fiberglass for more than 40 years. This misleading exposure history was mainly because he was only familiar with the dangers of asbestos. Since most fiberglass lung diseases are reversible and the symptoms of heart failure resolve soon after surgery, only observation was needed. Ten months after radical pericardiectomy, his symptoms, pleural effusion, and impaired pulmonary function eventually resolved. CONCLUSION: Fiberglass could cause inflammation of the pericardium, resulting in pericardial effusion and constrictive pericarditis, which could be severe and require radical pericardiectomy. Exact exposure history and histopathological examinations are the key to diagnosis.

Pericardial Diseases: International Position Statement on New Concepts and Advances in Multimodality Cardiac Imaging.

Pericardial diseases have gained renewed clinical interest, leading to a renaissance in the field. There have been many recent advances in pericardial diseases in both multimodality cardiac imaging of diagnoses, such as recurrent, transient constrictive and effusive-constrictive pericarditis, and targeted therapeutics, especially anti-interleukin (IL)-1 agents that affect the inflammasome as part of autoinflammatory pathophysiology. There remains a large educational gap for clinicians, leading to variability in evaluation and management of these patients. The latest pericardial imaging (American Society of Echocardiography, European Association of Cardiovascular Imaging) and clinical guidelines (European Society of Cardiology) are >8-10 years of age and may not reflect current practice. Recent clinical trials involving anti-IL-1 agents in recurrent pericarditis, including anakinra (AIRTRIP), rilonacept (RHAPSODY), and goflikicept have demonstrated their efficacy. The present document represents an international position statement from world leaders in the pericardial field, focusing on novel concepts and emphasizing the role of multimodality cardiac imaging as well as new therapeutics in pericardial diseases.

The "Old yet New" Echocardiographic Finding for Constrictive Pericarditis Following Purulent Pericarditis: A Case Report.

Purulent pericarditis (PP) is a localized infection of the pericardial cavity with suppuration that can be life-threatening. Treatment for PP consists of pericardial drainage and antimicrobial therapy. Constrictive pericarditis (CP), a form of diastolic heart failure that arises because an inelastic thickened pericardium, is a possible related dreadful complication of PP. Several echocardiographic findings suggestive of CP have been reported, but some require measurements or are difficult to reproduce. This case report presents a simple echocardiographic finding that reflects the clinical course of transient CP (TCP). A 76-year-old Japanese man presented to our hospital with chest pain and dyspnea. He was diagnosed with PP caused by Streptococcus pyogenes and treated with pericardial drainage and benzylpenicillin. The response to the treatment of the infection was favorable, but subsequent echocardiography and cardiac catheterization revealed a CP complication. Treatment with colchicine and ibuprofen was initiated, with improvement in CP within three months. During CP, a restricted right ventricular (RV) motion and movement of the liver towards the heart were observed before other echocardiographic findings suggestive of CP. Furthermore, this echocardiographic finding disappeared and normalized as CP improved. In this case of TCP following PP, changes in the echocardiographic "RV sliding" sensitively reflected the clinical course of CP. This simple finding may indicate inflammation of the pericardium and could be useful for the diagnosis and follow-up of CP.

An Atypical Presentation of Viral Myocarditis Masquerading as Non-ST-Elevation Myocardial Infarction (NSTEMI).

Coxsackie B virus is primarily associated with fever, pharyngitis, and gastrointestinal symptoms, while myocarditis is rarely reported. We present a rare case of a 47-year-old male with a history of hypertension and obesity, who developed Coxsackie B virus-induced myositis, myocarditis, and polyarthralgia. The patient presented with worsening back pain radiating to his chest, migratory arthralgia, exertional dyspnea, and bilateral shoulder pain with arm weakness. Initial investigations revealed elevated creatinine kinase (CK) levels and troponin I, alongside a high white blood cell (WBC) count and C-reactive protein (CRP) levels. Given the patient's symptoms and uptrending troponin without EKG changes, there was a high concern for non-ST-elevation myocardial infarction (NSTEMI), leading to initial treatment with aspirin and IV heparin. However, further questioning revealed a recent sore throat and contact with an ill family member, prompting investigations for an infectious etiology. A viral panel confirmed Coxsackie B virus infection. The patient made a full recovery with supportive care. This case highlights the importance of considering viral causes, particularly the Coxsackie B virus, in patients presenting with muscle pain, cardiac symptoms, and joint pain. Comprehensive viral testing is crucial for early identification and appropriate management to prevent long-term complications. Understanding the mechanisms of Coxsackie B virus infection is essential for developing effective treatment strategies addressing both the viral infection and the inflammatory response.

A case of acute purulent pericarditis due to MRSA treated with daily pericardial lavage for one month followed by pericardial fenestration.

Acute purulent pericarditis is a rare infection in developed countries. We herein report a case with diabetic nephropathy under maintenance hemodialysis who suffered from acute purulent pericarditis caused by methicillin-resistant Staphylococcus aureus (MRSA). The treatment of purulent pericarditis mainly involves rapid administration of appropriate antibiotics and drainage. However, in this case, the patient was unresponsive to vancomycin and performing early surgical intervention was challenging due to highly pathogenic MRSA. Therefore, we performed pericardial fenestration in the chronic phase to suppress the risk of fatal secondary infections after daily irrigation for one month to reduce bacterial load mechanically. Learning objective: In a case of purulent pericarditis caused by highly pathogenic methicillin-resistant Staphylococcus aureus resistant to antibiotics and resulting in constrictive pericarditis, it was possible to perform pericardial fenestration in the chronic phase, while mitigating the risk of fatal secondary infections, by controlling the inflammation through daily irrigation for a long time to reduce the bacterial load mechanically.

Coronary periarteritis and pericarditis are rare but distinct manifestations of heart involvement in IgG4-related disease: a retrospective cohort study.

BACKGROUND: The heart can be involved in immunoglobulin (Ig)-G4-related disease (IgG4-RD). This study aimed to summarize the clinical features and efficacy of treatment for IgG4-RD patients with heart involvement. METHODS: We conducted a retrospective study enrolling 42 IgG4-RD patients with heart involvement from the IgG4-RD cohorts of the Peking Union Medical College Hospital and Beijing An Zhen Hospital, from 2010 to 2022. Clinical, laboratory, radiological data were collected, and treatment responses to glucocorticoids and immunosuppressants were analyzed. RESULTS: IgG4-related cardiac involvement is a rare part of the IgG4-RD spectrum. The incidences of coronary periarteritis and pericarditis were 1.2%(13/1075) and 3.1%(33/1075), respectively in our cohort. Valvular disease possibly related to IgG4-RD was detected in two patients. None of the patients with myocardial involvement were identified. The average age was 58.2 ± 12.8 years, with a male predominance (76.7%). Coronary artery CT revealed that mass-like and diffuse wall-thickening lesions were the most frequently observed type of coronary periarteritis. Pericarditis presented as pericardial effusion, localized thickening, calcification and mass. After treatment with glucocorticoid and immunosuppressants, all patients achieved a reduced IgG4-RD responder index score and achieved radiological remission. Two patients with coronary peri-arteritis experienced clinical relapses during the maintenance period. CONCLUSIONS: Cardiac involvement in IgG4-RD is rare and easily overlooked since many patients are asymptomatic, and the diagnosis relies on imaging. Patients showed a satisfactory response to glucocorticoid based treatment.

Impact of pericardial calcification on early postoperative outcomes after pericardiectomy: a retrospective observational study.

BACKGROUND: Owing to the lack of understanding of the clinical significance of pericardial calcification during pericardiectomy, whether pericardial calcification should be considered when determining the optimal timing for pericardiectomy is debatable. We aimed to investigate the effect of pericardial calcification on early postoperative outcomes in patients who underwent pericardiectomy for constrictive pericarditis. METHODS: Altogether, 44 patients who underwent pericardiectomy for constrictive pericarditis were enrolled. After excluding three patients who underwent concurrent surgeries, a total of 41 patients were categorized into two groups based on the presence of pericardial calcification as determined by preoperative computed tomography and pathological examination. Preoperative clinical and imaging characteristics, intraoperative data, and early postoperative outcomes were compared between the two groups. A multivariable analysis was performed to identify the factors associated with postoperative complications. RESULTS: The group with and without PC comprised 21 and 20 patients, respectively. No significant differences were observed in 30-day mortality (n = 1 [5%]) in the group with pericardial calcification and no mortality in the group without pericardial calcification (p > 0.999). Other early postoperative outcome variables did not demonstrate any significant differences between the two groups. However, the use of cardiopulmonary bypass was associated with postoperative complications (p < 0.009, odds ratio: 63.5, 95% confidence interval: 5.13-3400). CONCLUSIONS: Pericardial calcification did not significantly affect the postoperative outcomes after pericardiectomy. Further comprehensive studies, including those with larger sample sizes and longitudinal designs, are necessary to determine whether pericardial calcification can significantly influence the timing of surgical intervention.

Acute graft rejection mimicking constrictive pericarditis after heart transplantation. A case report.

Constrictive pericarditis (CP) is an infrequent complication following heart transplantation (HTx) and arises from diverse postoperative occurrences, including mediastinitis, pericardial effusion, or allograft rejection. Indeed, this rare clinical entity can be misdiagnosed as a rejection episode or restrictive cardiomyopathy. In this report, we present the case of a 43-year-old male who underwent HTx 1.5 years prior and was subsequently admitted to our center due to the gradual onset of symptoms indicative of right congestive heart failure, with an initial diagnosis of constrictive pericarditis.

La pericarditis constrictiva (PC) representa una complicación rara después de un trasplante de corazón (TC), derivada de diversos eventos posoperatorios como mediastinitis, derrame pericárdico o rechazo del injerto. De hecho, esta entidad clínica poco común puede ser diagnosticada erróneamente como un episodio de rechazo o miocardiopatía restrictiva. En este informe presentamos el caso de un hombre de 43 años que se sometió a un TC 1,5 años antes y que fue ingresado posteriormente a nuestra institución debido al inicio gradual de síntomas indicativos de insuficiencia cardíaca congestiva derecha, con diagnóstico inicial de pericarditis constrictiva.

Calcific pericarditis strangling the heart, an answer to unexplained heart failurediagnostic modalities.

Pericardial calcification is often found incidentally from imaging studies and may be a clue to constrictive pericarditis. Constrictive pericarditis often mimics other causes of heart failure, pulmonary, or liver disease, making it hard to diagnose. Tuberculosis is the most common infectious aetiology of Constrictive Pericarditis. Living in developing countries, such as Indonesia, should warn us of the possibility of tuberculous constrictive pericarditis as a differential diagnosis of unexplained heart failure. The presented case came with complaints of shortness of breath, especially on exertion for five years, which worsened in the last 6 months. The past history of pulmonary Tuberculosis with the Cardiac CT findings confirmed the diagnosis of Constrictive Pericarditis.

Unstable angina pectoris in a young male after first dose of COVID-19 MRNA- vaccine.

Some side effects regarding COVID-19 vaccination have been reported. The most common reports of cardiovascular issues were myocarditis and pericarditis. Although inflammation is the most common cause in this matter, there were only a few reports about ischaemic cases related to COVID-19 vaccines. These reports also commonly included older men who received a second dose of mRNA vaccination. We present a 25-year-old man with chest pain mimicking a heart attack after receiving the first dose of the mRNA COVID-19 vaccine. There were no known preceding cardiovascular risk factors. Workups were done, and the diagnosis made was unstable angina pectoris. This may remind physicians to increase awareness of cardiovascular side effects in this vaccination era, as it may be encountered even in younger patients. The patient was seen at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, in August 2022.

Purulent Streptococcus intermedius Pericarditis in the Setting of Histoplasma Mediastinal Lymphadenitis: A Case Report and Literature Review.

Purulent pericarditis is a rare and potentially life-threatening condition characterized by infection of the pericardial space. We describe a case of purulent bacterial pericarditis in a 41-year-old male with no significant medical or surgical history who had concomitant pulmonary Histoplasma infection. Streptococcus intermedius was the bacteria directly responsible for the pericardial infection, though co-infection with histoplasmosis likely predisposed him to develop purulent pericarditis. We hypothesize histoplasmosis caused mediastinal lymphadenopathy, facilitating contact between a necrotic lymph node and the pericardium and contiguous suppuration of bacteria to the pericardial space. We treated S. intermedius and Histoplasma capsulatum with ceftriaxone and amphotericin B, respectively. Additionally, the patient presented in cardiac tamponade requiring emergent pericardiocentesis and drain placement. His course was also complicated by pericardial constriction. Cardiac magnetic resonance confirmed this, showing inflamed pericardium and abnormal septal motion with inspiration, and he had symptoms refractory to antimicrobials and anti-inflammatories. As such, he required pericardiectomy. This case demonstrates maintaining suspicion for secondary infectious foci as a contributor to the pathogenesis of purulent pericarditis is important, as pulmonary histoplasmosis played a pivotal role in allowing S. intermedius to spread to the pericardium but was not the primary infection. It also highlights the multifaceted evaluation and management of purulent pericarditis, highlighting the role of echocardiography and emergent pericardial drainage if cardiac tamponade is present, the importance of targeted antimicrobial therapy, the superior ability of cardiac magnetic resonance to identify pericardial constriction as a sequela of purulent pericarditis, and indications for pericardiectomy.

Uremic Pericarditis and Cardiac Tamponade Resolving With Intensive Hemodialysis.

We present an interesting and complex case of cardiac tamponade due to uremic pericarditis (UP), resolving with intensive hemodialysis (HD). HD should be considered as first line management for patients with UP and pericardial effusion. Intensification of HD should be considered based on clinical presentation and severity of presentation.

Rosai-Dorfman Disease as Constrictive Pericarditis: An Unusual Childhood Presentation.

Rosai-Dorfman disease (RDD) is a rare, multisystemic, histiocytic disorder that usually presents with painless cervical lymphadenopathy. We describe a case of constrictive effusive pericarditis with congestive cardiac failure in a six-year-old child as an initial presentation of RDD. The child underwent pericardiectomy and was treated with steroids, following which the symptoms resolved entirely. While tuberculosis accounts for the majority of cases presenting with constrictive pericarditis in developing countries, the presentation of RDD can be easily missed if not kept in mind as a possibility. This case report documents the unique presentation of a rare disease.

COVID-19 Presenting as Encephalitis and Myopericarditis: A Report of a Rare Case.

COVID-19 might present with a wide range of clinical manifestations, from mild respiratory distress to severe multi-organ dysfunction. We present a unique case of complex COVID-19 presentation in a 45-year-old female who initially developed general symptoms such as fever, cough, headache, and weakness, which escalated to coma, requiring intubation and ICU admission. A brain MRI revealed lesions compatible with encephalitis, the cause of which remained unexplained after an in-depth clinical, laboratory, and imaging investigation. While in the ICU, the patient also developed cardiac tamponade, requiring pericardiocentesis, and atypical electrocardiographic changes. After treatment with steroids, her condition improved, and the patient was extubated and transferred to the ward. Upon checkup, cardiac MRI revealed fibrous tissue in the inferior cardiac wall and the adjacent intraventricular septum. In the absence of an alternative diagnosis, it might be important to consider the central nervous system and cardiac involvement in patients with COVID-19.
