The Relationship of Pleural and Pericardial Effusion With Pulmonary Hemodynamics in Patients With Pulmonary Hypertension

BACKGROUND

The relationship between the presence of pleural and pericardial effusion in reference to hemodynamic parameters remains unclear in ambulatory patients with pulmonary hypertension (PH).

METHODS

Consecutive patients who underwent right catheterization (RHC) for the evaluation of pulmonary hypertension were enrolled. Point-of- care ultrasound was performed prior to the RHC to determine the presence of pleural effusion and pericardial effusion. We conducted a cross-sectional study to determine the association between presence of pericardial and pleural effusion with pulmonary hemodynamic variables.

RESULTS

Twenty-five (78.1%) of 32 patients had evidence of PH by RHC. Mean pulmonary artery pressure of the population was 40.6 mmHg, and 68% (17/25) had WHO group I PH. Six (24.0%) of 25 PH patients had pleural effusions identified, of which 4 out of 6 (66.7%) had a pulmonary artery wedge pressure >15 mmHg. Eleven (44.0%) of the 25 PH patients were also found to have pericardial effusions, and most of those patients 10/11(90.9%) had an elevated right atrial pressure >10 mmHg. The presence of a pleural effusion was associated with a pulmonary artery wedge pressure >15 mmHg (p = 0.032) and the presence of a pericardial effusion was associated with a right atrial pressure >10 mmHg (p = 0.004). Detection of pleural effusion had a poor positive predictive value (67%) for the presence of pulmonary venous hypertension, whereas presence of a pericardial effusion was highly predictive (89%) of the presence of systemic venous hypertension.

CONCLUSIONS

Systemic venous hypertension was associated with the presence of pericardial effusions, while pulmonary venous hypertension is associated with pleural effusion development in ambulatory patients with pulmonary hypertension.

Tuberculous pericarditis with tamponade diagnosed concomitantly with COVID-19: a case report

Background

Tuberculous pericarditis is a rare manifestation of tuberculosis infection. COVID-19 pandemic poses a challenge in detecting uncommon diseases.

Case summary

A 47-year-old man was admitted with symptoms of COVID-19 infection. Rapid progression of cardiomegaly on radiograph with clinical deterioration were suggestive of pericardial tamponade. Urgent pericardiocentesis revealed haemoserous fluid, elevated adenosine deaminase, and positive tuberculous (TB) polymerase chain reaction (PCR). He was started on anti-TB therapy and Remdesivir with marked improvement of symptoms. Repeat echocardiogram and CT thorax showed resolution of pericardial fluid, and the patient remained well on discharge.

Discussion

This case highlights the difficulty in detecting a concomitant rare but important disease. The development of massive pericardial tamponade acutely is not pathognomonic for COVID-19, and a careful diagnostic process involving multi-modality imaging occurred to arrive at a diagnosis of tuberculosis.

What is the ideal approach for emergent pericardiocentesis using point-of-care ultrasound guidance?

BACKGROUND

Traditionally performed using a subxiphoid approach, the increasing use of point-of-care ultrasound in the emergency department has made other approaches (parasternal and apical) for pericardiocentesis viable. The aim of this study is to identify the ideal approach for emergency-physician-performed ultrasound-guided pericardiocentesis as determined by ultrasound image quality, distance from surface to pericardial fluid, and likely obstructions or complications.

METHODS

A retrospective review of point-of-care cardiac ultrasound examinations was performed in two urban academic emergency departments for the presence of pericardial effusions. The images were reviewed for technical quality, distance of effusion from skin surface, and predicted complications.

RESULTS

A total of 166 pericardial effusions were identified during the study period. The mean skin-to-pericardial fluid distance was 5.6 cm (95% confidence interval [95% CI] 5.2-6.0 cm) for the subxiphoid views, which was significantly greater than that for the parasternal (2.7 cm [95% CI 2.5-2.8 cm], P<0.001) and apical (2.5 cm [95% CI 2.3-2.7 cm], P<0.001) views. The subxiphoid view had the highest predicted complication rate at 79.7% (95% CI 71.5%-86.4%), which was significantly greater than the apical (31.9%; 95% CI 21.4%-44.0%, P<0.001) and parasternal (20.2%; 95% CI 12.8%-29.5%, P<0.001) views.

CONCLUSIONS

Our results suggest that complication rates with pericardiocentesis will be lower via the parasternal or apical approach compared to the subxiphoid approach. The distance from skin to fluid collection is the least in both of these views.

Pericardial effusion in anti-complement factor H antibody-associated atypical hemolytic uremic syndrome: two case reports

Hemolytic uremic syndrome (HUS), a cause of pediatric acute kidney injury (AKI), has a spectrum of extra-renal manifestations. While neurological and gastrointestinal system involvement is common, cardiac involvement is rare. This is more so with pericardial involvement, though it has been reported in a handful of HUS cases associated with shiga toxin-producing Escherichia coli (STEC HUS). However, this complication has scarcely been reported in atypical HUS (aHUS) where there is alternate complement abnormality or DKGE (diacylglycerol kinase epsilon) mutation. We describe two children diagnosed with anti-complement factor H (CFH) antibody-associated aHUS who had pericardial involvement. Two boys, one 10-year-old and another 8-year-old, presented with pallor, oliguria and hypertension. They both had microangiopathic haemolytic anemia, thrombocytopenia and AKI suggestive of HUS. Complement workup revealed elevated anti-CFH antibody titres. With a diagnosis of anti-CFH antibody aHUS, they were started on plasmapheresis, pulse methylprednisolone and cyclophosphamide. The first case developed cardiac tamponade during the second week of hospital stay for which he needed pigtail drainage and further immunosuppression with rituximab. He gradually improved and pigtail was removed. The second case presented with pericardial effusion which subsequently resolved during the course of treatment. Thus, our patients developed pericardial effusion, with one of them progressing to life-threatening cardiac tamponade. Therefore, it is prudent that we are aware of this complication while treating children with aHUS.

Chronic massive pericardial effusion: a case report and literature review

Chronic massive pericardial effusion without cardiac tamponade is relatively rare. Nearly half of all patients with chronic large pericardial effusion are asymptomatic. We report a case of a 77-year-old man who presented with an asymptomatic chronic massive pericardial effusion, with no evidence of cardiac tamponade or pericardial constriction during a 10-year follow-up. The patient had a complex history of lymph node tuberculosis, hypertension, hypothyroidism, and polycythemia vera, as well as high-dose ³¹P radiation exposure 45 years ago. There was no evidence of tuberculosis infection, hypothyroidism, malignant tumor, severe heart failure, uremia, trauma, severe bacterial or fungal infection, chronic myeloid leukemia, or bone marrow fibrosis after admission. The patient underwent pericardiocentesis twice. The pericardial effusion comprised exudate fluid with a high proportion of monocytes. The patient refused indwelling catheter drainage or pericardiectomy. The likely final diagnosis was recurrent chronic large idiopathic pericardial effusion.

Cardiac adverse events of immune checkpoint inhibitors in oncology patients: A systematic review and meta-analysis

BACKGROUND

Immune checkpoint inhibitors (ICIs) are novel therapeutic agents used for various types of cancer. ICIs have revolutionized cancer treatment and improved clinical outcomes among cancer patients. However, immune-related adverse effects of ICI therapy are common. Cardiovascular immune-related adverse events (irAEs) are rare but potentially life-threatening complications.

AIM

To estimate the incidence of cardiovascular irAEs among patients undergoing ICI therapy for various malignancies.

METHODS

We conducted this systematic review and meta-analysis by searching PubMed, Cochrane CENTRAL, Web of Science, and SCOPUS databases for relevant interventional trials reporting cardiovascular irAEs. We performed a single-arm meta-analysis using OpenMeta [Analyst] software of the following outcomes: Myocarditis, pericardial effusion, heart failure, cardiomyopathy, atrial fibrillation, myocardial infarction, and cardiac arrest. We assessed the heterogeneity using the I² test and managed to solve it with Cochrane’s leave-one-out method. The risk of bias was performed with the Cochrane’s risk of bias tool.

RESULTS

A total of 26 studies were included. The incidence of irAEs follows: Myocarditis: 0.5% [95% confidence interval (CI): 0.1%-0.9%]; Pericardial effusion: 0.5% (95%CI: 0.1%-1.0%); Heart failure: 0.3% (95%CI: 0.0%-0.5%); Cardiomyopathy: 0.3% (95%CI: -0.1%-0.6%); atrial fibrillation: 4.6% (95%CI: 1.0%-14.1%); Myocardial infarction: 0.4% (95%CI: 0.0%-0.7%); and Cardiac arrest: 0.4% (95%CI: 0.1%-0.8%).

CONCLUSION

The most common cardiovascular irAEs were atrial fibrillation, myocarditis, and pericardial effusion. Although rare, data from post market surveillance will provide estimates of the long-term prevalence and prognosis in patients with ICI-associated cardiovascular complications.

Percutaneous closure of an iatrogenic right ventricular perforation with an angio-seal vascular closure device: a case report

Background

Iatrogenic perforation of the right ventricle (RV) is a rare but recognized complication of pericardiocentesis. Treatment strategies for RV perforation include surgical repair and percutaneous closure. In this case report, we describe the use of an angio-seal vascular closure device (Terumo Interventional Systems) to seal an iatrogenic RV perforation secondary to incorrect placement of a pericardial drain.

Case summary

A 55-year-old female presented with an anterior ST-elevation myocardial infarction. Coronary angiography demonstrated occlusion of the left anterior descending artery. The patient went on to have primary percutaneous coronary intervention and both the left anterior descending and D1 were wired. During kissing balloon inflation, the Sion Blue wire migrated distally in the D1 causing an Ellis type 3 wire tip perforation in the distal D1. Emergency pericardiocentesis was performed however the 8 French (8 Fr) pericardial drain was inadvertently inserted into the RV. It was decided to attempt percutaneous closure with an 8 Fr angio-seal in the catheter lab under echocardiographic and fluoroscopic guidance. Our patient did not demonstrate any recurrence of pericardial effusion on repeat echocardiography over 60 days post-procedure.

Discussion

Our patient did not demonstrate any recurrence of pericardial effusion on repeat echocardiography over 60 days post-procedure. We feel that the angio-seal vascular closure device represents an effective, minimally invasive treatment for this rare but potentially catastrophic complication of pericardiocentesis. In this case, the technique spared our patient a sternotomy with its associated morbidity.

Case report of simultaneous presentation of pulmonary embolism and pericardial effusion following an oncological esophagectomy

•

First reported case of simultaneous pulmonary embolism and pericardial effusion following esophageal resection.

•

Contradicting anticoagulation indications poses a therapeutic challenge.

•

Rivaroxaban as possible cause of pericardial bleed.

Introduction

This is the first reported case of simultaneous presentation of pulmonary embolism and pericardial effusion following esophagectomy. This case illustrates a diagnostic and therapeutic challenge exemplifying the difficulties arising from complex anticoagulant considerations in esophageal cancer.

Patient case

A 72 year old male undergoes an oncological esophageal resection. Postoperatively the patient develops pulmonary embolism for which he is treated with Rivaroxaban. After starting Rivaroxaban the patient develops a large pericardial effusion.

Discussion

We suspect that the treatment of pulmonary embolism with Rivaroxaban had a causative role in the development of pericardial effusion. Based on literature we suspect that chemoradiotherapy increased susceptibility.

Conclusion

Diagnosis and treatment of simultaneous pulmonary embolism and pericardial effusion remains a challenge. Special consideration should be taken when using Rivaroxaban in esophageal cancer patients; this should always be conducted in consultation with a coagulation specialist.

Pericardial disease as a rare complication of pediatric appendicitis: a systematic literature search

BACKGROUND

Classic symptoms of acute appendicitis are well known but are uncommon and often misinterpreted in pediatric patients, potentially delaying diagnosis and resulting in rare sequelae.

METHODS

We conducted a comprehensive systematic literature search of case reports detailing pericardial disease as a rare complication of pediatric appendicitis through MEDLINE, Embase, and Cochrane Databases. Inclusion criteria was that the patient must be < 18 years old and present with both pericardial disease and appendicitis.

RESULTS

Our search yielded 7 cases with an average age of 10.3 ± 3.9 years old. The cases involved cardiac tamponade, pericarditis, and/or pericardial effusion. Five cases were diagnosed with appendicitis before complicated by pericardial disease. Most cases had an infectious component, but a majority had negative pericardial fluid cultures. Pleural effusion and abdominal abscesses were other common complications of pediatric appendicitis.

CONCLUSION

Awareness of this uncommon relationship may have prognostic value as this may facilitate appropriate management of pericardial effusions, tamponade, and/or appendicitis.

Development and validation of a novel prediction score for cardiac tamponade in emergency department patients with pericardial effusion

Aims

Determining which patients with pericardial effusion require urgent intervention can be challenging. We sought to develop a novel, simple risk prediction score for patients with pericardial effusion.

Methods and results

Adult patients admitted through the emergency department (ED) with pericardial effusion were retrospectively evaluated. The overall cohort was divided into a derivation and validation cohort for the generation and validation of a novel risk score using logistic regression. The primary outcome was a pericardial drainage procedure or death attributed to cardiac tamponade within 24 h of ED arrival. Among 195 eligible patients, 102 (52%) experienced the primary outcome. Four variables were selected for the novel score: systolic blood pressure < 100 mmHg (1.5 points), effusion diameter [1–2 cm (0 points), 2–3 cm (1.5 points), >3 cm (2 points)], right ventricular diastolic collapse (2 points), and mitral inflow velocity variation > 25% (1 point). The need for pericardial drainage within 24 h was stratified as low (<2 points), intermediate (2–4 points), or high (≥4 points), which corresponded to risks of 8.1% [95% confidence interval (CI) 3.0–16.8%], 63.8% [95% CI 50.1–76.0%], and 93.7% [95% CI 84.5–98.2%]. The area under the curve of the simplified score was 0.94 for the derivation and 0.91 for the validation cohort.

Conclusion

Among ED patients with pericardial effusion, a four-variable prediction score consisting of systolic blood pressure, effusion diameter, right ventricular collapse, and mitral inflow velocity variation can accurately predict the need for urgent pericardial drainage. Prospective validation of this novel score is warranted.

Purulent pericarditis in a patient with community-acquired methicillin-resistant Staphylococcus aureus: a case report with mini-review

Introduction

The etiopathogenesis of purulent pericarditis has changed significantly in modern antibiotic era with the emergence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) in the last few decades. Pericarditis due to MRSA is rarely reported in the literature without risk factors like immunosuppression, thoracic surgery, chest trauma or pre-existing pericardial diseases.

Case report

We describe an 18-year-old male who presented with 5 days history of fever, chest pain and shortness of breath. Echocardiogram and thorax CT showed significant pericardial effusion. The patient underwent pericardiocentesis, MRSA was isolated from blood and pericardial fluid. The patient improved with intravenous antibiotics (linezolid). Follow-up echocardiography at 3 months was unremarkable, without any residual fluid or features of constrictive pericarditis.

Discussion

In the absence of known risk factors, MRSA is an extremely rare cause of pericarditis in modern antibiotics era. The possibility of MRSA pericarditis should be sought in every case of pericarditis to achieve prompt diagnosis and treatment.

Conclusions

Our case highlights the role of aggressive pericardiocentesis and appropriate antibiotic therapy in purulent pericarditis.

Parameters predicting COVID-19-induced myocardial injury and mortality

Clinical manifestations of COVID-19 affect many organs, including the heart. Cardiovascular disease is a dominant comorbidity and prognostic factors predicting risk for critical courses are highly needed. Moreover, immunomechanisms underlying COVID-induced myocardial damage are poorly understood.

OBJECTIVE

To elucidate prognostic markers to identify patients at risk.

RESULTS

Only patients with pericardial effusion (PE) developed a severe disease course, and those who died could be identified by a high CD8/Treg/monocyte ratio. Ten out of 19 COVID-19 patients presented with PE, 7 (78%) of these had elevated APACHE-II mortality risk-score, requiring mechanical ventilation. At admission, PE patients showed signs of systemic and cardiac inflammation in NMR and impaired cardiac function as detected by transthoracic echocardiography (TTE), whereas parameters of myocardial injury e.g. high sensitive troponin-t (hs-TnT) were not yet increased. During the course of disease, hs-TnT rose in 8 of the PE-patients above 16 ng/l, 7 had to undergo ventilatory therapy and 4 of them died. FACS at admission showed in PE patients elevated frequencies of CD3⁺CD8⁺ T cells among all CD3+ T-cells, and lower frequencies of Tregs and CD14⁺HLA^-DR⁺-monocytes. A high CD8/Treg/monocyte ratio predicted a severe disease course in PE patients, and was associated with high serum levels of antiviral cytokines. By contrast, patients without PE and PE patients with a low CD8/Treg/monocyte ratio neither had to be intubated, nor died.

CONCLUSIONS

PE predicts cardiac injury in COVID-19 patients. Therefore, TTE should be performed at admission. Immunological parameters for dysfunctional antiviral immunity, such as the CD8/Treg/monocyte ratio used here, supports risk assessment by predicting poor prognosis.

Assessment of Pericardial Disease with Cardiovascular MRI

Disorders of the pericardium are common and can result in significant morbidity and mortality. Advances in multimodality imaging have enhanced our ability to diagnose and stage pericardial disease and improve our understanding of the pathophysiology of the disease. Cardiovascular MRI (CMR) can be used to define pericardial anatomy, identify the presence and extent of active pericardial inflammation, and assess the hemodynamic consequences of pericardial disease. In this way, CMR can guide the judicial use of antiinflammatory and immune modulatory medications and help with timing of pericardiectomy. CMR can also be used to diagnose congenital disorders of the pericardium. Furthermore, CMR can be used to define pericardial masses and understand their malignant potential.

[Infectious and inflammatory complications occurring after cardiac surgery in cardiac rehabilitation centres]

Patients undergoing cardiac surgery are older, have complex pathologies and several comorbidities, but need to leave the hospital quickly! Therefore, the mission of cardiac rehabilitation centres has substantially changed. Indeed, if 15 to 25% of patients undergoing cardiac surgery will have a postoperative complication requiring a hospital management (infectious, pericardial, rhythmic, neurologic, pulmonary, digestive, etc.), more than 2/3 of these acute events could be managed by cardiac rehabilitation centres for a lower cost. Therefore, the quickest the patient is transferred to a cardiac rehabilitation centre, the easier the cardiac surgery centre could manage his beds. Infectious complications are the most dreadful, particularly mediastinitis.

Massive pericardial effusion and cardiac tamponade revealed undiagnosed Turner syndrome: a case report

Background

Patients with Turner syndrome (TS) are prone to autoimmune disorders. Although most patients with TS are diagnosed at younger ages, delayed diagnosis is not rare.

Case presentation

A 31-year-old woman was presented with facial edema, chest tightness and dyspnea. She had primary amenorrhea. Physical examination revealed short stature, dry skin and coarse hair. Periorbital edema with puffy eyelids were also noticed with mild goiter. Bilateral cardiac enlargement, distant heart sounds and pulsus paradoxus, in combination with hepatomegaly and jugular venous distention were observed. Her hircus and pubic hair was absent. The development of her breast was at 1st tanner period and gynecological examination revealed infantile vulva. Echocardiography suggested massive pericardial effusion. She was diagnosed with cardiac tamponade based on low systolic pressure, decreased pulse pressure and pulsus paradoxus. Pericardiocentesis was performed. Thyroid function test and thyroid ultrasound indicated Hashimoto’s thyroiditis and severe hypothyroidism. Sex hormone test revealed hypergonadotropin hypogonadism. Further karyotyping revealed a karyotype of 45, X [21]/46, X, i(X) (q10) [29] and she was diagnosed with mosaic + variant type of TS. L-T4 supplement, estrogen therapy, and antiosteoporosis treatment was initiated. Euthyroidism and complete resolution of the pericardial effusion was obtained within 2 months.

Conclusion

Hypothyroidism should be considered in the patients with pericardial effusion. The association between autoimmune thyroid diseases and TS should be kept in mind. Both congenital and acquired cardiovascular diseases should be screened in patients with TS.

[Delayed tamponade: Four cases of rare complication of blunt chest trauma]

Delayed post-traumatic pericardial effusion is a rare condition after blunt trauma. The diagnosis of the effusion can be made by the clinical signs, which is not very specific and the cardiac echography. The etiological diagnosis remains difficult because it requires the elimination of the other causes of pericarditis. Their treatment consists in evacuating the pericardial effusion. The evolution thereafter is simple. We report four cases of patients with pericardial effusion late after a thoracic injury. Imaging the blood test, the examination of the pericardial fluid and the anatomopathological examination of the pericardium, eliminates the other etiologies.

The management of cardiac implantable electronic device lead perforations: a multicentre study

AIMS

Lead perforation is a rare, well-known complication of cardiac implantable electronic device (CIED) implants, whose management is mostly not evidence-based. Main management strategies include conservative approach based on clinical and lead function follow-up vs. routine invasive lead revision approach. This study compared the complications of both strategies by composite endpoint, including recurrent perforation-related symptoms, recurrent pericardial effusion (PEf), lead dysfunction, and device infection during 12 month follow-up.

METHODS AND RESULTS

Multicentre retrospective analysis, inquiring data from imaging studies, device interrogation, pericardiocentesis, and clinical charts of patients with suspected perforating leads between 2007 and 2014 in five hospitals. All cases were reviewed by electrophysiologist and defined as definite perforations by suggestive symptoms along with lead perforation on imaging, bloody PEf on pericardiocentesis shortly after implant, or right ventricular (RV) lead non-capture along with diaphragmatic stimulation upon bipolar pacing. Clinical outcomes associated with both management approaches were compared, with respect to the composite endpoint. The study included 48 definitive perforation cases: 22 managed conservatively and 26 via lead revision. Conservative management was associated with an increased composite endpoint compared with lead revision (8/22 vs. 1/26; P = 0.007). The dominant complication among the conservative cohort was appearance of cardiac tamponade during follow-up; 5/6 occurring in cases which presented with no or only mild PEf and were treated by antiplatelets/coagulants during or shortly after CIED implantation.

CONCLUSION

A conservative management of CIED lead perforation is associated with increased complications compared with early lead revision. Lead revision may be the preferred management particularly in patients receiving antiplatelets/coagulants.

Cardiovascular images: constrictive pericarditis and tricavitary effusion in a dog with pericardial mesothelioma

This report describes the transthoracic echocardiographic findings and computed tomography features of a 12-year-old West Highland white terrier with constrictive pericarditis (CP) secondary to pericardial mesothelioma. Although pericardial mesothelioma is well described in dogs, its association with CP in the canine population is not as widely reported. In this clinical case, a multidisciplinary imaging approach was helpful to identify anatomical and hemodynamic abnormalities that allowed for a diagnosis of CP.

Extrapulmonary manifestations of COVID-19: Radiologic and clinical overview

COVID-19 is principally a respiratory illness and pulmonary manifestations constitute main presentations of the disease. According to the reported studies, SARS-CoV-2 infection is not limited to the respiratory system and other organs can be also affected. Renal dysfunction, gastrointestinal complications, liver dysfunction, cardiac manifestations, mediastinal findings, neurological abnormalities, and hematological manifestations are among the reported extrapulmonary features. Considering the broad spectrum of clinical manifestations and the increasing worldwide burden of the disease, there is an urgent need to rapidly scale up the diagnostic capacity to detect COVID-19 and its complications. This paper focuses on the most common extrapulmonary manifestations in patients with COVID-19 pneumonia. Further studies are needed to elaborate and confirm the causative relationship between SARS-CoV-2 and the reported extrapulmonary manifestations of COVID-19.

Cement-related embolism after lumbar vertebroplasty: A case report

BACKGROUND

Cement-related embolism is a rare but potentially fatal complication in spinal surgery. Cardiac echocardiography can provide valuable information for the early identification.

CASE SUMMARY

A 66-year-old woman who underwent lumbar vertebroplasty and internal fixation under general anesthesia experienced an episode of supraventricular tachycardia and ventricular tachycardia at the end of surgery. Point-of-care echocardiogram revealed a foreign body in the right heart. After conservative treatment in the intensive care unit, her family decided on comfort care and she expired.

CONCLUSION

Transthoracic echocardiography may provide early valuable information in patients undergoing vertebroplasty, and mild-moderate pericardial effusion may be a significant sign of a poor outcome.

Constrictive pericarditis after heart transplantation: a case report

Background

Constrictive pericarditis (CP) is a disease characterized by inflammation, progressive fibrosis, and thickening of the pericardium. Constrictive pericarditis after heart transplantation (HT) is a rare phenomenon, with a reported incidence of 1.4-3.9%. It is an important clinical problem which shares similar clinical features with entities such as restrictive cardiomyopathy. Therefore, it poses diagnostic challenges and therapeutic dilemmas even for experienced clinicians.

Case summary

A 53-year-old patient developed a zoster infection with pericardial effusion 9 months after HT for idiopathic dilated cardiomyopathy. Two months later, he presented with leg oedema and ascites and was treated by diuretics for volume overload. He was readmitted 8 months later with features of right heart failure. Multimodal imaging investigations were suggestive of CP. He successfully recovered after a radical pericardiectomy.

Discussion

Constrictive pericarditis is a rare complication in HT. Heart transplant recipients (HTR) with a history of post-operative pericardial effusion, or with rejection episodes are at high risk of developing CP. Differentiating CP from other conditions that cause apparent congestive heart failure in HTR is challenging. Management of CP is mainly surgical pericardiectomy.

Pericardial effusion with tamponade – an uncommon presentation leading to the diagnosis of eosinophilic granulomatosis polyangiitis: A case report

BACKGROUND

Eosinophilic granulomatosis polyangiitis (EGPA) is a small vessel necrotizing vasculitis that commonly presents as peripheral eosinophilia and asthma; however, it can rarely manifest with cardiac involvement such as pericarditis and cardiac tamponade. Isolated pericardial tamponade presenting as the initial symptom of EGPA is exceedingly rare. Early diagnosis and appropriate treatment are crucial to prevent life-threatening outcomes.

CASE SUMMARY

52-year-old woman with no past medical history presented with progressive dyspnea and dry cough. On physical exam she had a pericardial friction rub and bilateral rales. Vital signs were notable for tachycardia at 119 beats per minute and hypoxia with 89% oxygen saturation. On laboratory exam, she had 45% peripheral eosinophilia, troponin elevation of 1.1 ng/mL and N-terminal prohormone of brain natriuretic peptide of 2101 pg/mL. TTE confirmed a large pericardial effusion and tamponade physiology. She underwent urgent pericardial window procedure. Pericardial and lung biopsy demonstrated eosinophilic infiltration. Based on the American College of Radiology guidelines, the patient was diagnosed with EGPA which manifested in its rare form of cardiac tamponade. She was treated with steroid taper and mepolizumab.

CONCLUSION

This case highlights that when isolated pericardial involvement occurs in EGPA, diagnosis is recognized by performing pericardial biopsy demonstrating histopathologic evidence of eosinophilic infiltration.

Pericardial effusion and cardiac tamponade requiring pericardial window in an otherwise healthy 30-year-old patient with COVID-19: a case report

Background

This case report demonstrates pericardial effusion, acute pericarditis, and cardiac tamponade in an otherwise healthy woman who had a positive test result for coronavirus disease 2019. Few case reports have been documented on patients with this presentation, and it is important to share novel presentations of the disease as they are discovered.

Case presentation

A Caucasian patient with coronavirus disease 2019 returned to the emergency department of our hospital 2 days after her initial visit with worsening chest pain and shortness of breath. Imaging revealed new pericardial effusion since the previous visit. The patient became hypotensive, was taken for pericardial window for cardiac tamponade with a drain placed, and was treated for acute pericarditis.

Conclusion

Much is still unknown about the implications of coronavirus disease 2019. With the novel coronavirus disease 2019 pandemic, research is still in process, and we are slowly learning about new signs and symptoms of the disease. This case report documents a lesser-known presentation of a patient with coronavirus disease 2019 and will help to further understanding of a rare presentation.
