Cardiac Tamponade and Pericardiocentesis: Recognition, Standard Techniques, and Modern Advancements.

Pericardiocentesis is an important diagnostic and therapeutic procedure. In the setting of cardiac tamponade, pericardiocentesis can rapidly improve hemodynamics, and in cases of diagnostic uncertainty, pericardiocentesis allows for fluid analysis to aid in diagnosis. In contemporary practice, the widespread availability of ultrasonography has made echocardiographic guidance the standard of care. Additional tools such as micropuncture technique, live ultrasonographic guidance, and adjunctive tools including fluoroscopy continue to advance and enhance procedural efficiency and safety. When performed by experienced operators, pericardiocentesis is a safe, effective, and potentially life-saving procedure.

Pericardial Effusion in Association With Periodontitis: Case Report and Review of 8 Patients in Literature.

Periodontal diseases are well-known background for infective endocarditis. Here, we show that pericardial effusion or pericarditis might have origin also in periodontal diseases. An 86-year-old man with well-controlled hypertension and diabetes mellitus developed asymptomatic increase in pericardial effusion. Two weeks previously, he took oral new quinolone antibiotics for a week because he had painful periodontitis along a dental bridge in the mandibular teeth on the right side and presented cheek swelling. The sputum was positive for Streptococcus species. He was healthy and had a small volume of pericardial effusion for the previous 5 years after drug-eluting coronary stents were inserted at the left anterior descending branch 10 years previously. The differential diagnoses listed for pericardial effusion were infection including tuberculosis, autoimmune diseases, and metastatic malignancy. Thoracic to pelvic computed tomographic scan demonstrated no mass lesions, except for pericardial effusion and a small volume of pleural effusion on the left side. Fluorodeoxyglucose positron emission tomography disclosed many spotty uptakes in the pericardial effusion. The patient denied pericardiocentesis, based on his evaluation of the risk of the procedure. He was thus discharged in several days and followed at outpatient clinic. He underwent dental treatment and pericardial effusion resolved completely in a month. He was healthy in 6 years until the last follow-up at the age of 92 years. We also reviewed 8 patients with pericarditis in association with periodontal diseases in the literature to reveal that periodontal diseases would be the background for developing infective pericarditis and also mediastinitis on some occasions.

Chylopericardium following esophagectomy: a case report and systematic review.

BACKGROUND: Chylopericardium is a rare condition characterized by the accumulation of chyle in the pericardial space. It is most commonly caused by thoracic duct injury. Chylopericardium following esophagectomy is extremely rare but can cause life-threatening complications. This report presents a case of chylopericardium post-esophagectomy, resulting in cardiac tamponade and cardiac arrest. A systematic literature review was also conducted to facilitate the understanding of this rare condition. CASE PRESENTATION: A 41-year-old male was admitted to our hospital with intermediate to highly differentiated squamous cell carcinoma of the mid-thoracic esophagus (clinical T4NxM0). He underwent thoracoscopic-laparoscopic esophagectomy with cervical anastomosis. On postoperative day 1, patient had a cardiac arrest secondary to cardiac tamponade, requiring emergency ultrasound-guided drainage. The drained fluid was initially serous but became chylous after the administration of enteral nutritional emulsion. As a result of significant daily pericardial drainage, patient subsequently underwent thoracic duct ligation. The amount of drainage was substantially reduced post-thoracic duct ligation. Over a period of 2 years and 7 months, patient recovered well and tolerated full oral diet. A comprehensive literature review was conducted and 4 reported cases were identified. Among these cases, three patients developed pericardial tamponade secondary to chylopericardium post-esophagectomy. CONCLUSION: Chylopericardium is a rare but serious complication post-esophagectomy. Prompt echocardiography and thorough pericardial fluid analysis are crucial for diagnosis. Thoracic duct ligation has been shown to be an effective management approach for this condition.

Initial diagnosis of extranodal NK/T-cell lymphoma in pericardial fluid with concomitant hemophagocytic lymphohistiocytosis (HLH).

Extranasal natural killer/T-cell lymphoma arising in the heart is rare and typically presents with non-specific clinical symptoms, necessitating a biopsy for a definitive diagnosis. We report an unusual case of a 48-year-old male who initially presented with chest pain and shortness of breath. Subsequent diagnosis via pericardial fluid analysis, including flow cytometry and immunohistochemical stains, revealed extranasal NK/T-cell lymphoma without sinonasal involvement. The analysis identified neoplastic lymphoid cells expressing CD2, cytoplasmic CD3, Epstein-Barr virus, and CD56 and exhibiting increased Ki-67 staining. Additionally, the patient developed hemophagocytosis lymphocytosis secondary to NK/T cell lymphoma. Treatment included an interleukin-1 receptor antagonist (anakinra), dexamethasone, rituximab, and etoposide. Unfortunately, the patient's condition rapidly deteriorated, leading to multiorgan failure and eventual demise. Given the rarity of this lymphoma, early diagnosis based on a high suspicion level provides the best chance for improved overall survival.

Cardiac Tuberculosis: A Case Series from Ethiopia, Italy, and Uganda and a Literature Review.

Extrapulmonary tuberculosis (TB) is estimated to account for up to 20% of active cases of TB disease, but its prevalence is difficult to ascertain because of the difficulty of diagnosis. Involvement of the heart is uncommon, with constrictive pericarditis being the most common cardiac manifestation. Diagnostic research for cardiac disease is frequently lacking, resulting in a high mortality rate. In addition to direct cardiac involvement, instances of cardiac events during antitubercular therapy are described. This case series describes five cases of TB affecting the heart (cardiac TB) from Italy and high-burden, low-income countries (Ethiopia and Uganda), including a case of Loeffler syndrome manifesting as myocarditis in a patient receiving antitubercular therapy. Our study emphasizes how cardiac TB, rare but important in high-burden areas, is a leading cause of pericardial effusion or pericarditis. Timely diagnosis and a comprehensive approach, including imaging and microbiological tools, are crucial. Implementing high-sensitivity methods and investigating alternative samples, such as detection of tuberculosis lipoarabinomannan or use of the GeneXpert assay with stool, is recommended in TB control programs.

Blunt cardiac injury in the hemodynamically stable patient.

ABSTRACT: Blunt cardiac injury (BCI) describes a spectrum of problems including severe, potentially life-threatening injuries from trauma. Pericardial effusion is an example of a BCI that has generally been assumed to imply serious underlying injury to the heart and should be considered hemopericardium until proven otherwise. A standard of care has been established to screen for BCI and treat hemodynamically unstable patients with an acute pericardial effusion presumably related to BCI. Less agreement exists on definitive treatment for hemodynamically stable patients with pericardial effusion after blunt cardiac trauma. This case study explores a new treatment for small to moderate hemopericardium in a stable patient after BCI.

Pleural and pericardial effusions with fever and altered mental status: an atypical presentation of bartonellosis.

A male in his 60s presented to the emergency department (ED) with a 3-week history of fever and progressive confusion. Initial laboratory and radiographic workup was largely unremarkable except for moderate bilateral pleural effusions. The patient was admitted on broad-spectrum antibiotics and further workup for fever of unknown aetiology. The differential diagnosis was broadened to different zoonotic infections, and subsequent laboratory testing showed a markedly elevated Bartonella henselae IgG and Bartonella quintana IgG (1:4096 and 1:512, respectively) in addition to positive B. henselae IgM titre (>1:20). During hospitalisation, the patient became more hypoxic and was found to have enlarging pleural effusions as well as a new pericardial effusion. The patient was treated with intravenous then oral doxycycline 100 mg two times per day and oral rifampin 300 mg two times per day for 4 weeks with subsequent improvement in clinical status as well as both effusions. This case highlights a unique presentation of Bartonella and its rare manifestation of pleural and pericardial effusions.

Spontaneous resolution of an intrapericardial thrombus as a complication of pericardiocentesis in a neonate.

We present the case of a premature neonate with pericardial effusion secondary to extravasation of total parenteral nutrition from a mispositioned/migrated umbilical venous catheter. Emergency pericardiocentesis was complicated by an intrapericardial thrombus, which was managed conservatively with spontaneous resolution within 24 hours. This case illustrates that the rare complication of an intrapericardial thrombus after pericardiocentesis can be successfully managed conservatively with close monitoring in haemodynamically stable paediatric patients.

A Transesophageal Cardiovascular Intervention.

Endoscopic ultrasonography-guided transesophageal pericardiocentesis was performed for a posteriorly located effusion not amenable to transthoracic drainage in a 58-year-old woman with a history of recurrent breast adenocarcinoma who presented with dyspnea. The patient had a pericardial effusion that resulted in cardiac tamponade. Transthoracic pericardiocentesis was unsuitable because of the posterior location of the effusion. Pericardiocentesis via the transesophageal route was performed. The pericardial sac was punctured with a 19-gauge needle, and 245 mL of pericardial fluid were aspirated, resulting in the resolution of the tamponade physiology. Endoscopic ultrasonography-guided transesophageal drainage is a novel and promising therapeutic option for posteriorly located pericardial effusions.

[Exudative pericarditis with tamponade after COVID-19. Case report].

A description of a COVID-19 patient with the development of exudative pericarditis complicated by cardiac tamponade is provid. A peculiarity of this case is the presence of an underlying disease in the patient (chronic lymphocytic leukemia), which was in remission for 1.5 years after chemotherapy. Another feature of the patient was the relatively small area of lung damage and the hemorrhagic nature of the pericardial effusion, which persisted for a long time. The insignificant activity of inflammatory markers was noteworthy. Possible mechanisms of development and features of the course of exudative pericarditis in the described patient, issues of diagnosis and treatment of this category of patients are discusse.

Pyopericardium presenting as pericardial tamponade in a patient with common variable immunodeficiency disorder.

A male patient in his 20s with a medical history of common variable immunodeficiency disorder, non-compliant with therapy, presented to the emergency department with respiratory distress and severe hypoxaemia. Chest radiography demonstrated extensive bilateral infiltrates and an increased cardiothoracic ratio. Streptococcus pneumoniae urine antigen test was positive. ECG demonstrated diffuse ST-segment elevation. An arterial line was placed and demonstrated pulsus paradoxus. Transthoracic echocardiography revealed an extensive pericardial effusion, with echocardiographic signs of cardiac tamponade. Emergency subxiphoid pericardiocentesis was performed with an initial drainage of 750 mL of purulent fluid consistent with pyopericardium. Immediate haemodynamic improvement was observed. The patient required a second pericardiocentesis for drainage of a relapsing pericardial effusion. The course was complicated by effusive-constrictive pericarditis requiring anterior interphrenic pericardiectomy. Treatment with intravenous immunoglobulin and antibiotics led to a complete recovery.

Pericardial Windows: The Limited Diagnostic Value of Non-Targeted Pericardial Biopsy. / Janelas Pericárdicas: O Valor Limitado do Diagnóstico da Biópsia Pericárdica não Guiada.

BACKGROUND: Pericardial window, in addition to promoting pericardial drainage, can also provide samples of the pericardium for anatomopathological examination. However, such biopsies' contribution to clarifying the etiology of pericardial effusion has been debated. OBJECTIVE: To analyze the diagnostic value of non-targeted pericardial biopsy obtained from pericardial window procedures. METHODS: Data from 80 patients who had undergone parietal pericardial biopsies from 2011 to 2020 were retrospectively reviewed. Statistical significance was considered if p < 0.05. RESULTS: Fifty patients were male (62.5%,) and 30 were female (37.5%). The median age was 52 years (interquartile range: 29 to 59) and 49 years (interquartile range: 38 to 65), respectively (p = 0.724). The suspected etiology of pericardial effusion was neoplastic in 31.3%, unclear in 25%, tuberculosis in 15%, autoimmune in 12.5%, edemagenic syndrome in 7.5%, and other miscellaneous conditions in 8.8%. The most frequent approach for pericardial drainage and biopsy was subxiphoid (74%), followed by video-assisted thoracoscopy (22%). Overall, in 78.8% of the biopsies, the histopathologic findings were compatible with nonspecific inflammation, and only 13.7% of all biopsies yielded a conclusive histopathological diagnostic. Those suffering from cancer and pericardial effusion had a higher proportion of conclusive histopathologic findings (32% had pericardial neoplastic infiltration). The hospital mortality rate was 27.5%, and 54.5% of the patients who died in the hospital had cancer. No deaths were attributed to cardiac tamponade or the drainage procedure. CONCLUSION: Our results showed that pericardial window is a safe procedure, but it had little value to clarify the pericardial effusion etiology and no impact on the planned therapy for the primary diagnosis besides the cardiac decompression.

FUNDAMENTO: A janela pericárdica, além de promover a drenagem pericárdica, também pode fornecer amostras do pericárdio para exame anatomopatológico. No entanto, a contribuição dessas biópsias para a elucidação da etiologia do derrame pericárdico tem sido debatida. OBJETIVO: Analisar o valor diagnóstico da biópsia pericárdica não guiada obtida de procedimentos de janela pericárdica. MÉTODOS: Foram revisados retrospectivamente dados de 80 pacientes submetidos a biópsia pericárdica parietal de 2011 a 2020. A significância estatística foi considerada quando p < 0,05. RESULTADOS: Cinquenta pacientes eram do sexo masculino (62,5%) e 30 do sexo feminino (37,5%). A mediana de idade foi de 52 anos (intervalo interquartil: 29 a 59) e 49 anos (intervalo interquartil: 38 a 65), respectivamente (p = 0,724). A etiologia suspeita do derrame pericárdico foi neoplásica em 31,3%, incerta em 25%, tuberculose em 15%, autoimune em 12,5%, síndrome edemigênica em 7,5% e outras condições diversas em 8,8%. A abordagem mais frequente para drenagem pericárdica e biópsia foi a subxifoide (74%), seguida pela videotoracoscopia (22%). Em 78,8% das biópsias, os achados histopatológicos foram compatíveis com inflamação inespecífica, e apenas 13,7% de todas as biópsias produziram um diagnóstico histopatológico conclusivo. Aqueles que sofriam de câncer e derrame pericárdico apresentaram maior proporção de achados histopatológicos conclusivos (32% apresentavam infiltração neoplásica pericárdica). A taxa de mortalidade hospitalar foi de 27,5% e 54,5% dos pacientes que morreram no hospital tinham câncer. Nenhuma morte foi atribuída ao tamponamento cardíaco ou ao procedimento de drenagem. CONCLUSÃO: Nossos resultados mostraram que a janela pericárdica é um procedimento seguro, mas teve pouco valor para esclarecer a etiologia do derrame pericárdico e nenhum impacto na terapia planejada para o diagnóstico primário além da descompressão cardíaca.

Pericardial malignant mesothelioma diagnosed in a dog by immunocytochemistry of the pericardial fluid: a case report.

BACKGROUND: Pericardial effusions are one of the most common cardiac diseases in dogs. Common causes of haemorrhagic pericardial effusions include neoplasia, such as hemangiosarcoma, mesothelioma, chemodectoma, and ectopic thyroid tumours, and benign idiopathic pericardial effusion. Distinguishing among reactive mesothelial cells, malignant mesothelioma, and adenocarcinoma in body effusions is a diagnostic challenge. Therefore, the author aimed to discover whether the observed cells were reactive mesothelial, mesothelioma, or adenocarcinoma cells through immunocytochemistry using five markers (cytokeratin, vimentin, desmin, E-cadherin, and calretinin) in a canine patient. CASE PRESENTATION: A 2.1 kg, spayed female, 10-year-old Yorkshire Terrier dog presented to a local hospital with dyspnoea and was evaluated for pericardial effusion. The presence of pericardial fluid was confirmed, and she was referred to our hospital for further evaluation. In cytological evaluation, cells shed individually or in clusters were observed, along with numerous non-degenerative neutrophils and macrophages. The cells showed binucleation, anisocytosis, anisokaryosis, abnormal nucleoli, abundant basophilic cytoplasm, high nuclear-cytoplasmic ratio, and coarse chromatin. Large atypical multinucleate cells were also observed. Erythrophagia was observed, indicating chronic haemorrhage. Immunocytochemistry using pericardial fluid was positive for cytokeratin, vimentin, desmin, E-cadherin, and calretinin. Therefore, malignant mesothelioma was diagnosed. CONCLUSIONS: Immunocytochemistry is a very useful diagnostic technique because it can determine whether several fluorescent markers are simultaneously expressed in the same cell. Further, E-cadherin and calretinin can be used for the differential diagnosis of reactive mesothelial cells, malignant mesothelioma, and adenocarcinoma in dogs.

Safety and efficacy of ablation for atrial fibrillation in combination with left atrial appendage occlusion in octogenarians.

BACKGROUND: Catheter ablation (CA) combined with left atrial appendage occlusion (LAAO) is a feasible approach for atrial fibrillation (AF) patients. Its role in octogenarians with AF is unclear. HYPOTHESIS: In AF patients over 80 years, CA combined with LAAO is a feasible way in restoring sinus rhythm and preventing stroke. METHODS: This is a single-center retrospective study. Patients who underwent CA and LAAO in a single procedure between March 2018 and December 2020 were included. Efficacy endpoints included procedural success rate, AF recurrence rate, and thromboembolic events. Safety endpoints included pericardial effusion/cardiac tamponade, device-related thrombus (DRT), all-cause death, and major bleeding. RESULTS: Five hundred and five patients (mean age 69.5 ± 7.7 years; 230 [45.5%] female) were included, with 46 (9.1%) patients aged ≥80 years old (octogenarian group). Prevalence of paroxysmal AF (25 [54.3%] vs. 207 [45.1%], p < 0.001) and CHA2DS2VASc score (4.1 ± 1.3 vs. 3.1 ± 1.4, p < 0.0001) were higher in octogenarian patients. There were six cases (1.2%) of pericardial effusion (all in nonoctogenarian patients). At 3 months postprocedure, 437 patients underwent TEE/CT. Thirty-two (80%) octogenarian patients and 308 (77.6%) nonoctogenarian patients had no peri-device leak. After a mean follow-up of 26.9 ± 9.1 months, AF was documented in 10 (21.7%) patients in octogenarian group and in 103 (22.4%) patients in nonoctogenarian group (p = 0.99). The annual thromboembolic risk was 2.1% and 0.8% in the octogenarian group and nonoctogenarian group, respectively. Death occurred in 16 nonoctogenarian patients. One major bleeding was recorded in the octogenarian group. CONCLUSIONS: The combination of CA and LAAO in a single procedure is a feasible treatment option in octogenarians with comparable efficacy and safety profile.

Haemorrhagic Mycobacterium avium complex pericarditis presenting with cardiac tamponade in an immunocompetent woman.

A young woman in her mid-40s was referred by her primary care physician for fever, worsening shortness of breath, pleuritic chest pain and tachycardia. CT angiogram of the chest revealed a large pericardial effusion. Echocardiogram confirmed tamponade physiology despite her being haemodynamically stable. She had an emergency pericardiocentesis which revealed evidence of a haemorrhagic pericardial effusion. However, the patient was still symptomatic after treatment and had to undergo video-assisted thoracoscopic surgery with a pericardial window and chest tube. Postoperatively, her fevers resolved. Pan-culture was initially negative, and all antibiotics were discontinued. Acid-fast bacilli cultures later grew Mycobacterium avium complex. She continued to have chest discomfort postoperatively, but follow-up CT of the chest 3 months postoperatively showed continued resolution of her pericardial effusion. The patient's symptoms improved, and she has had no recurrence of effusion without the need for anti-tuberculosis drugs.

Cardiac tamponade.

Cardiac tamponade is a medical emergency caused by the progressive accumulation of pericardial fluid (effusion), blood, pus or air in the pericardium, compressing the heart chambers and leading to haemodynamic compromise, circulatory shock, cardiac arrest and death. Pericardial diseases of any aetiology as well as complications of interventional and surgical procedures or chest trauma can cause cardiac tamponade. Tamponade can be precipitated in patients with pericardial effusion by dehydration or exposure to certain medications, particularly vasodilators or intravenous diuretics. Key clinical findings in patients with cardiac tamponade are hypotension, increased jugular venous pressure and distant heart sounds (Beck triad). Dyspnoea can progress to orthopnoea (with no rales on lung auscultation) accompanied by weakness, fatigue, tachycardia and oliguria. In tamponade caused by acute pericarditis, the patient can experience fever and typical chest pain increasing on inspiration and radiating to the trapezius ridge. Generally, cardiac tamponade is a clinical diagnosis that can be confirmed using various imaging modalities, principally echocardiography. Cardiac tamponade is preferably resolved by echocardiography-guided pericardiocentesis. In patients who have recently undergone cardiac surgery and in those with neoplastic infiltration, effusive-constrictive pericarditis, or loculated effusions, fluoroscopic guidance can increase the feasibility and safety of the procedure. Surgical management is indicated in patients with aortic dissection, chest trauma, bleeding or purulent infection that cannot be controlled percutaneously. After pericardiocentesis or pericardiotomy, NSAIDs and colchicine can be considered to prevent recurrence and effusive-constrictive pericarditis.
