Purpose: Cardiothoracic surgeons are frequently called upon to perform surgical pericardial drainage procedures (pericardial window) for pericardial effusions. These procedures have therapeutic value, but the diagnostic value of such procedures is debated. We set out to determine the sensitivity of pericardial drainage to detect the disease when cytology, microbiology, and pathology are evaluated., Methods: A retrospective chart review of patients who underwent pericardial windows from 1 July 2011 to 1 January 2018 at a single academic institution was conducted. All patients who had undergone a recent trauma or cardiac procedure were excluded. Cytology, microbiology, and pathology were examined. The charts were then carefully reviewed to determine if a clinical diagnosis was reached. Sensitivity was then calculated for all diseases and for those that should have been able to be detected., Results: One hundred sixty-two patients who had undergone a pericardial drainage procedure were identified; 49 patients were excluded for recent cardiac procedure or trauma. Of the 113 patients who met our inclusion criteria, 56 patients (49.6%) were female with a mean age of 59.7 ± 15.1 years. A diagnosis based on the pathology, microbiology, or cytology was obtained for 27 patients. The most common pathologies detected were adenocarcinoma (11), bacteremia (9), and small cell lung cancer (3); 56 patients had underlying pathologies that would have been possible to detect with either pathology, microbiology, or cytology. The most common detectable diagnoses were adenocarcinoma (20), bacteremia (12), and lymphoma (7). The most common undetectable diagnoses were idiopathic (17), cardiorenal fluid overload (17), and viral (11). The sensitivity of a pericardial drainage procedure for detecting disease was 0.24 for all cases, and 0.48 when restricted to cases where a detectable disease was present., Conclusion: Cytology, microbiology, and pathology for pericardial drainage procedures were unable to detect a diagnosis for 76% of all cases and greater than 50% of cases with the theoretically detectable disease. Pericardial drainage procedures have a clear therapeutic value, but they have limited diagnostic utility., (© 2019 The Authors. Journal of Cardiac Surgery published by Wiley Periodicals, Inc.)

Background/purpose: Pericardial effusion (PE) is a complication of pulmonary hypertension (PHT) and, specifically, pulmonary arterial hypertension (PAH), that confers a worse prognosis. The safety of performing pericardiocentesis in patients with PHT has not been established. We aimed to assess the safety and feasibility of performing pericardiocentesis in patients with significant PHT., Methods/materials: We performed a retrospective analysis from August 2013 to December 2018 at our tertiary-care center of patients who underwent a pericardiocentesis procedure. Patients, procedure, echocardiographic findings, any major intraprocedural complications, and post-procedural related complications up to 30 days were recorded. Specifically, we studied patients with significant PHT., Results: The cohort included 170 patients, with an average age of 62.6 years and an even distribution of gender and co-morbidities. The etiology for the PE varied. Major complications were rare (1.7%) and only 10 patients (5.9%) required re-intervention for reaccumulation of fluid. There were 27 patients (15.9%) with significant PHT, 5 with World Health Organization (WHO) Group I PAH (2.94%). In the entire cohort, there were only 3 major complications (1.7%), none among PHT patients., Conclusions: Pericardiocentesis is a safe procedure, including in patients with significant PHT, including those with WHO Group I PAH. We advocate the use of invasive hemodynamic monitoring in patients with significant PHT., Summary: Pericardiocentesis tends to be a safe procedure. However, the safety of performing pericardiocentesis in patients with significant pulmonary hypertension has not been well established. We aimed to assess the safety and feasibility of performing pericardiocentesis, and specifically in patients with significant PHT out our tertiary center by performing a retrospective analysis., (Copyright © 2019 Elsevier Inc.

Purpose of Review: To review the echo-Doppler findings in effusive-constrictive pericarditis (ECP). ECP corresponds to the coexistence of a hemodynamically significant pericardial effusion and markedly reduced compliance of the pericardium, manifested by constrictive physiology post-pericardiocentesis., Recent Findings: We summarize herein the recent observations regarding the prevalence of ECP based on echocardiography as well as the pre- and post-pericardiocentesis echo-Doppler features of ECP. ECP diagnosed by echocardiography was seen in approximately 15% of patients with ECP pre- and post-pericardiocentesis echo-Doppler findings sharing features with both cardiac tamponade and constrictive pericarditis. ECP post-pericardiocentesis is common but its natural history in the current era might be better than previously reported. Further studies and (particularly simultaneous echocardiography-cardiac catheterization) are still critically needed to better understand the underlying hemodynamics of ECP. Moreover, it remains to be determined whether pre- and post-pericardiocentesis echo-Doppler findings can be used to prognosticate or to guide therapy of those undergoing pericardiocentesis.

A 70-year-old man underwent cardiac surgery including left atrial appendage closure. A pigtail catheter was inserted into the pericardial sac because of delayed tamponade. Removal of the catheter was planned for 2 days after drain insertion. However, the resistance was high and pulsatile. The patient was transferred to the catheterization laboratory and a guide wire was inserted through the catheter, revealing the catheter route around the left atrial appendage. The wire was exchanged for a stiff wire to uncurl the catheter as much as possible, then the catheter was removed. The left atrial appendage does not usually represent an obstacle to catheter removal because it is soft and shrinkable. However, once the left atrial appendage becomes closed off, it can become hard, unshrinkable and an obstacle that might be caught by the drainage catheter.

Objective: To describe a 3-port right-sided thoracoscopic subtotal pericardiectomy (TSP) to treat dogs with recurrent idiopathic pericardial effusion (RIPE) and report their long-term survival., Study Design: Retrospective case series., Animals: Sixteen client-owned dogs., Methods: Medical records were searched for dogs with idiopathic pericardial effusion that recurred after 1 or more pericardiocenteses and treated with a 3-port right-sided technique (1 subxiphoid camera port and 2 instrument ports on the right side of the dog). Follow-up consisted of direct examination or communication with referring veterinarians or owners., Results: Thoracoscopic subtotal pericardiectomy was successfully completed in all dogs, with no surgical complications. The median duration of postoperative follow-up was 191.5 days (range, 5-1345). The median survival time (MST) after surgery was 365 days (range, 5-1345); MST of dogs with a histopathological diagnosis of neoplasia (n = 4) was 76 days, whereas dogs with no evidence of neoplasia had an MST of 367 days (n = 12, P = .14). Recurrent pleural effusion was the ultimate cause of death or reason for euthanasia in 8 of 16 dogs., Conclusion: The technique described here resulted in similar surgical times and outcomes for dogs undergoing TSP for RIPE compared with previous studies. Neoplasia was identified in 4 of 16 dogs., Clinical Significance: Thoracoscopic subtotal pericardiectomy can be readily performed with only 2 instrument ports, both on the same side of the dog, and without 1-lung ventilation. Recurrent pleural effusion led to the death of half of the dogs in this series., (© 2019 The American College of Veterinary Surgeons.)

BACKGROUND Pericarditis is common in rheumatoid arthritis, mostly occurring as an extra-articular manifestation of the disease. We describe a patient with stable rheumatoid arthritis who presented with a large pericardial effusion and a compressive fibrotic pericardial mass. The patient had recently started treatment with a tumor necrosis factor-alpha (TNF-alpha) antagonist. CASE REPORT The patient was a 58-year-old woman with rheumatoid arthritis who presented with right ventricular compression caused by a pericardial fibrotic mass and a large pericardial effusion. The patient did not have active arthritis at the time of presentation. She had been started on treatment with a tumor necrosis factor-alpha (TNF-alpha) antagonist 4 months prior to this presentation. She was successfully treated with surgical pericardiectomy and resection of the pericardial mass. Pathologic analysis of the pericardial mass demonstrated fibrosis and no evidence of active inflammation, rheumatoid arthritis, opportunistic infection, or malignancy. CONCLUSIONS We describe a patient with stable rheumatoid arthritis who developed subacute right heart compression syndrome secondary to pericardial effusion and fibrous pericardial mass. The exact cause of pericarditis and the pericardial mass remain uncertain. There is a need for increased awareness of the association between use of TNF-alpha antagonists and the possible development of an intrapericardial fibrotic mass and effusion.

Mesothelioma is a very aggressive malignant tumor with low survival rates that is often diagnosed belatedly. Pericardial effusion is a common consequence in cases of mesothelioma, with pericardiocentesis and pericardiectomy indicated; therefor thoracocentesis is necessary to drain the contents no longer retained in the pericardium. The present report describes a mesothelioma-carrying dog with a history of cardiac tamponade that underwent thoracoscopic pericardiectomy and, later, thoracoscopic implantation of a fully implantable catheter to function as a thoracic drain. In the consulted literature, there is no use of a fully implantable catheter for this purpose. The authors consider that there was an improvement in the quality of life.

Purpose: In the treatment of the postsurgical pericardial effusions via pericardiocentesis, determination of the puncture site might be difficult. Contrast echocardiography may not be efficient due to surgical artefacts and pulmonary problems and therefore may lead to inaccurate evaluation. Alternative imaging methods might be helpful to perform the pericardiocentesis with decreased complications., Methods: We retrospectively analyzed the patients who had undergone pericardiocentesis in our department from January 2008 through April 2018. The procedure was performed in slightly semi-seated position with the guidance of the echocardiography and fluoroscopy. Following the catheterization, percutaneous drainage was performed., Results: There were 63 patients needed intervention due to pericardial effusion. 67% of the patients were using warfarin and the next patients were using acetyl salicylic acid and/or clopidogrel. All effusions were in the posterolateral localization. The mean volume of aspirated pericardial fluid was 404 ± 173 mL (150-980 mL). Control echocardiograms showed that almost all fluid was drained in all patients and there were no procedural or follow-up complications., Conclusion: In the treatment of postoperative pericardial effusion, fluoroscopy is an alternative method to locate the catheter accurately in challenging situations following cardiac surgery. Thus, procedural risk minimizes and drainage of pericardial fluid is performed safely.

Objectives: The pericardial effusion (PE) caused by paragonimiasis is rarely reported. This study aims to present experience in the diagnosis and surgical management of PE due to paragonimiasis., Methods: Medical records of 57 children who were diagnosed with PE due to paragonimiasis and underwent surgery at Children's Hospital of Chongqing Medical University between January 2012 and August 2018 were retrospectively reviewed., Results: The average age of this group was 7.6 ± 3.0 years. Patients were mainly from Chongqing and Sichuan areas. ELISA for Paragonimus skrjabini in all 57 patients showed positive results. Moderate or large PE were identified in 12 and 45 patients, respectively. All patients underwent surgery either by pericardectomy or thoracoscopic surgery. Pathological exams indicated massive eosinophil infiltration in all 57 specimens. After 3-4 courses of praziquantel therapy, the clinical outcomes were satisfactory., Conclusions: Typical endemic history, eosinophilia and multiple serous effusion raise suspicions of paragonimiasis. Once moderate to large PE is identified in patients with paragonimiasis, surgical treatment is necessary., (Copyright © 2019 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Objective: To report the outcome of dogs with presumptive echocardiographic idiopathic pericardial effusion treated with thoracoscopic pericardectomy and pericardioscopy., Study Design: Multi-institutional retrospective study (2011-2017)., Animals: Eighteen dogs., Methods: Records were searched for dogs with pericardial effusion and no identified cause by preoperative echocardiography and subsequent thoracoscopic pericardectomy and pericardioscopy. Collected data included presenting complaint, physical examination, laboratory results, imaging, and operative findings. Follow-up was obtained via telephone interview and/or recheck examination., Results: No evidence of mass lesions or cause for the effusion was identified in any of the dogs by preoperative echocardiography. Nine dogs had unremarkable pericardioscopic examination results. Nine dogs had pericardioscopic abnormalities consistent with masses, nodules, or adhesions. Median survival time (MST) for the 9 dogs with abnormalities identified by pericardioscopy was 66 days, whereas MST for the 9 dogs with unremarkable pericardioscopic examination results was not reached (P = .0067). Median survival time for dogs based on histopathologic diagnosis alone was not different between dogs with a diagnosis of neoplasia and dogs with a diagnosis of pericarditis (P = .1056). Among dogs with lesions identified during pericardioscopy, MST did not differ between those with a diagnosis of malignancy and those with a diagnosis of pericarditis (P = .78)., Conclusion: Dogs with presumptive idiopathic pericardial effusion without evidence of masses, nodules, and/or adhesions during thoracoscopic pericardectomy and pericardioscopy lived longer than dogs in which abnormalities were identified during pericardioscopy., Clinical Significance: Thoracoscopic pericardectomy/pericardioscopy and targeted biopsy of the pericardium and pleura are recommended in dogs with echocardiographic idiopathic pericardial effusion., (© 2018 The American College of Veterinary Surgeons.)

A rare case of extramedullary multiple myeloma causing cardiac tamponade secondary to a plasma cell-based pericardial effusion is described. A systematic search using PubMed (National Library of Medicine) was used to identify a further 27 cases dating back to 1970. Case characteristics, treatment strategies, and survival time following tamponade are discussed. Linear regression demonstrated a weak but statistically significant correlation between survival time following tamponade and treatment with systemic chemotherapy and steroids (β=16.8 weeks, P=.009). However, this manifestation of extramedullary multiple myeloma still conveys a dismal prognosis with a median survival following tamponade of only 6 weeks based on our review., (Copyright © 2019 Elsevier Inc.

Case reports have reported immune checkpoint inhibitors (ICI), especially nivolumab, are associated with recurrent pericardial effusions. Our objective was to determine how often patients being treated with ICI develop hemodynamically significant pericardial effusion requiring pericardiocentesis compared with other cancer therapeutics and whether the survival of patients who underwent pericardiocentesis differs according to ICI use versus standard cancer therapeutics. Our institutional review board approved catheterization laboratory data collection for all pericardiocenteses performed and all patients receiving ICI from January 1, 2015 to December 31, 2017. Retrospective review of the electronic medical record was performed to identify cancer therapeutics given preceding pericardiocentesis. Log-rank analysis was performed to compare survival in patients requiring pericardiocentesis between those on ICI and those not on ICI. Overall, 3,966 patients received ICI of which only 15 pericardiocenteses were required, including 1 repeat pericardiocentesis in a patient on nivolumab. The prevalence of pericardiocentesis among patients on ICI was 0.38% (15/3,966). Eleven pericardiocenteses were performed after nivolumab infusion, 3 after pembrolizumab, and 1 after atezolizumab, with pericardiocentesis prevalences for each agent of 0.61% (11/1,798), 0.19% (3/1,560), and 0.32% (1/309), respectively. One hundred and twenty pericardiocentesis were performed on patients receiving other cancer therapeutics although no therapeutic agent was associated with more pericardiocenteses than nivolumab. In conclusion, the prevalence of hemodynamically significant pericardial effusions and ICI administration is uncommon, and survival durations after pericardiocentesis for patients receiving ICI and those not receiving ICI are similar, suggesting that frequent echocardiographic monitoring for pericardial effusions is not necessary., (Copyright © 2019 Elsevier Inc.

Objective: In this retrospective study, we aimed to observe the efficacy of pericardial effusion (PE) treatments by a survey conducted at the Department of Cardiovascular Surgery, Faculty of Medicine, Atatürk University., Methods: In order to get comparable results, the patients with PE were divided into three groups - group A, 480 patients who underwent subxiphoid pericardiostomy; group B, 28 patients who underwent computerized tomography (CT)-guided percutaneous catheter drainage; and group C, 45 patients who underwent echocardiography (ECHO)-guided percutaneous catheter drainage., Results: In the three groups of patients, the most important symptom and physical sign were dyspnea and tachycardia, respectively. The most common causes of PE were uremic pericarditis in patients who underwent tube pericardiostomy, postoperative PE in patients who underwent CT-guided percutaneous catheter drainage, and cancer-related PE in patients who underwent ECHO-guided percutaneous catheter drainage. In all the patients, relief of symptoms was achieved after surgical intervention. There was no treatment-related mortality in any group of patients. In patients with tuberculous pericarditis, the rates of recurrent PE and/or constrictive pericarditis progress were 2,9% and 2,2% after tube pericardiostomy and ECHO-guided percutaneous catheter drainage, respectively., Conclusion: Currently, there are many methods to treat PE. The correct treatment method for each patient should be selected according to a very careful analysis of the patient's clinical condition as well as the prospective benefit of surgical intervention.

Background: Pericardial effusion is a common feature of end-stage liver disease. In this case report we describe the intraoperative management of recurrent pericardial effusion, without re-pericardiocentesis, to prevent circulatory collapse during a critical surgical time-point; that is, during manipulation of the major vessels and graft reperfusion., Methods: A 47-year-old woman with hepatitis B was scheduled to undergo deceased donor liver transplantation (LT). A large pericardial effusion was preoperatively identified using transthoracic echocardiography (TTE). The patient also had paroxysmal atrial fibrillation. Two days before surgery, preemptive pericardiocentesis was performed and the 1150-mL effusion was drained. Intraoperatively, recurrence of the large pericardial effusion was identified using transesophageal echocardiography (TEE). During inferior vena cava manipulation, the surgeon consulted the anesthesiologist to evaluate the hemodynamic changes in the patient. After 3 attempts, the transplant team was able to determine the most appropriate anastomosis site, defined as that with the least impact on cardiac function. To prevent the development of severe postreperfusion syndrome, 10% MgSO 4 (2 g) was gradually infused 20 minutes before portal vein declamping, and immediately before graft reperfusion a 100-μg bolus of epinephrine was administered., Results: During graft reperfusion, there was no evidence of heart chamber collapse or flow disturbance, as seen on the TEE findings. Postoperatively, the patient recovered completely and was discharged from the hospital. Six months after surgery, there was no sign of pericardial effusion on follow-up TTE., Conclusion: Our intraoperative strategy may prevent cardiac collapse in patients with pericardial effusion detected during LT. Intraoperative TEE plays an important role in guiding hemodynamic management., (Copyright © 2019 Elsevier Inc. All rights reserved.)

A 23-year-old man, diagnosed with Wolff-Parkinson-White syndrome and who had undergone several catheter ablations, presented 2 months after the most recent ablation with cardiac tamponade following physical exertion. Emergency surgery revealed a perforation between the inferior vena cava and the right atrium. This perforation was repaired with a bovine pericardium patch. To our knowledge, this is the first case of delayed cardiac tamponade after catheter ablation due to a Valsalva manoeuvre (such as weightlifting) in a patient with a normal international normalized ratio and normal platelet count.

Introduction: Pericarditis is an inflammation of the pericardium. It may be infectious or secondary to a systemic disease. The aim of this study was to analyze the clinical findings, course, treatment and follow-up of children diagnosed with pericarditis at our center., Methods: We performed a retrospective analysis of all children admitted to our pediatric cardiology unit with pericarditis between 2003 and 2015. Patient characteristics were summarized using frequencies and percentages for categorical variables and medians with percentiles for continuous variables., Results: Fifty patients were analyzed (40 male, 10 female) with a median age of 14 years. The most common diagnosis was acute pericarditis (80%). Thirty-five patients (70%) presented with chest pain and 26% reported fever. Cardiomegaly was identified on chest X-ray in 11 patients (22%), 30 patients (60%) had an abnormal ECG and 44 patients (80%) had alterations on the transthoracic echocardiogram. In 17 cases (34%) there was myocardial involvement. Forty-eight percent of patients presented with infectious pericarditis and the pathologic agent was identified in half of them. Postpericardiotomy syndrome was diagnosed in five cases. The first-line therapy was aspirin in 50% of cases. Pericardiocentesis was performed in 12 patients. The median length of stay was nine days. There was symptom recurrence in seven children., Conclusions: In this study, acute infectious pericarditis was the most common presentation and about one third of patients also had myocarditis. The symptom recurrence rate was not negligible and is probably related to the type of therapy employed., (Copyright © 2019 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U.

Patients with pericardial disease often require interventional therapies or surgery, making it essential for anesthesiologists to understand the altered physiology of these disease states and the resultant impact on perioperative management. The broad spectrum of syndromes involving the pericardium present with varying degrees of clinical significance, from asymptomatic presentations to life-threatening emergencies. Impaired diastolic filling of the heart represents a common theme of pericardial disease, with the rate of onset of pericardial pathology largely determining the extent of this impairment and subsequent severity of presentation. This review highlights recent updates in the literature regarding the diagnostic evaluation, medical therapy, and invasive therapeutic procedures for common pericardial syndromes from the perspective of a perioperative physician., (Copyright © 2018 Elsevier Inc.

Introduction: Pericardial effusion (PE) is a complication of late-stage cancer and some patients never leave the hospital despite drainage. The main objective of this study was to identify predictors of hospital discharge in cancer patients with (PE) who underwent pericardial drainage. We also report the occurrence of paradoxical hemodynamic instability (PHI)., Methods and Materials: A retrospective study was carried out in a cancer center. Patients included had malignancy, PE, and underwent surgical drainage. An institutional database was reviewed for preoperative variables, analyzed for hospital discharge., Results: One-hundred and thirteen patients were included, with a mean age of 54 years old (SD 14.3). Sixty-three patients were discharged from hospital (55.7%). Age (odds ratio [OR], 1.04; P = 0.004), higher ECOG status (OR, 0.63; P = 0.019), recent chemotherapy (OR, 3.40; P = 0.007), and renal failure (OR, 0.14; P = 0.002) were associated with hospital discharge. Median survival was 43 days (IQ 25%-75%; 15-162). Patients with pulmonary embolism or neutropenia were at greater risk of developing PHI (OR, 10.11; P = 0.009 and OR, 12.13; P = 0.015, respectively)., Conclusion: Almost half of the patients never left the hospital. Patients with no chemotherapy within 45 days of procedure, patients with renal failure and higher ECOG status are at greater risk of not getting discharged. PHI remains a serious condition with high mortality., (© 2018 Wiley Periodicals, Inc.)

Background: Emergent ultrasound-guided pericardiocentesis (USGP) is an uncommonly performed procedure by emergency physicians (EPs). USGP simulation models have previously been developed to increase procedural proficiency, but these models are limited for routine implementation secondary to high-cost, lengthy time to construct, and lack of durability. The objective of this study was to develop an USGP simulation model that is cost-effective, easily and rapidly constructed, and has procedure-specific fidelity., Discussion: We have developed a novel tofu simulation model for USGP training. The model cost per unit was $1.81 and the average construction time was 2.5 ± 0.3 min. The model can withstand upward of 100 needle punctures. Our model provides USGP procedure-specific aspiration of a simulated pericardial effusion., Conclusions: The tofu USGP model provides a cost-effective and rapidly constructible simulation tool that could be readily integrated in EP procedural training., (Copyright © 2018 Elsevier Inc.

Background: National registries have provided data on in-hospital outcomes for several cardiac procedures. The available data on in-hospital outcomes and its predictors after pericardiocentesis are mostly derived from single center studies. Furthermore, the outcomes after pericardiocentesis for iatrogenic pericardial effusion and the impact of procedural volume on in-hospital outcomes in the United States are largely unknown., Methods: We used national inpatient database files for the years 2009-2013 to estimate the inpatient outcomes after pericardiocentesis in all-comers and in the subgroups with iatrogenic effusion. We also studied the impact of hospital procedural volume, among other predictors, on inpatient mortality., Results: About 64,070 (95%CI 61 008-67 051) pericardiocentesis were performed in the United States during 2009-2013. Of these, 57.15% (56.02-58.26%) of the pericardiocentesis were in hemodynamically unstable patients. Percutaneous cardiac procedures were performed in 17.7% of patients (percutaneous coronary intervention (PCI) 4.02%, electrophysiologic procedures 13.58%, and structural heart intervention (SHI) 0.76%). Overall inpatient mortality was 12.30% (95%CI 11.66-12.96%). Inpatient mortality after PCI, electrophysiologic procedures, SHI and cardiac surgery were 27.67% (95%CI 24-31.67%), 7.8% (95%CI 6.67-9.31%), 22.36% (95%CI 15.06-31.85%) and 18.97% (95%CI 15.84-22.57%), respectively. There was an inverse association between hospital procedural volume and inpatient mortality, with a mortality of 14.01% (12.84-15.26%) at the lowest and 10.82% (9.44-12.37%) at highest quartile hospitals by procedure volume (p trend  = 0.001)., Conclusion: The inpatient mortality after pericardiocentesis is high, particularly when associated with PCI and SHI., (© 2018 Wiley Periodicals, Inc.)

Spontaneous pericardial hematoma is rare, and the diagnosis of spontaneous organized hemopericardium is difficult in some cases. The present study reports a case of a 23-year-old man admitted to our hospital for dyspnea on Sept. 30, 2017. The patient experienced shortness of breath 10 days before admission and went to a local hospital. The chest non-contrast CT and Echo revealed effusion of pericardium, right thoracic cavity and abdominal cavity. The patient went to our hospital for further treatment, and there was no abnormality in the laboratory tests of infection, tumor, or immune disease. The patient received pericardiocentesis for cardiac tamponade. A re-examination of Echo after pericardiocentesis revealed a pericardial mass. The enhanced chest CT and 18F-FDG PET/CT could not rule out the risk of a malignant tumor. The resection of pericardial mass was performed under cardiopulmonary bypass with cardioplegia. The pathology was organized hematoma with widely hemorrhage and necrosis, fibrous tissue proliferation, myofibroblast proliferation, and granulation tissue formation. The patient was discharged from our hospital without recurrence of pericardial effusion or the symptom of dyspnea. This case suggests that spontaneous organized hemopericardium is difficult to be distinguished from malignant tumor, and a surgical resection can help with diagnosis and symptomatic relief.

Malignancy is a common cause of pericardial effusions. The findings, immediate safety and longer-term outcomes of pericardiocentesis are less well defined. We reviewed the cases of all patients with malignancy that underwent pericardiocentesis at our institution over a 10-year period. From January 1, 2007 to December 31, 2016, 171 patients with cancer underwent echo-guided pericardiocentesis. A total of 53% were male with a mean age of 60 ± 15 years. The average volume drained was 485 (IQR 350 to 719) ml. The procedure was technically successful in 170/171 (99.4%) of patients without significant complications; there were no procedure-related deaths. A total of 20% had hemorrhagic, 48% had serosanguinous, and 31% serous pericardial effusions. The type of effusion was not associated with outcome. Cytology (measured in 164) was positive in 58% and only weakly related to outcome (median survival nine versus 18 weeks, p = 0.04). Per our institutional practice, a pericardial catheter was left in place until there were less than 50 ml of net drainage in 24 hours (average 3 ± 2 days). A total of 135 patients had metastatic carcinoma, 23 patients had lymphoma or chronic leukemia and 4 metastatic sarcoma. Patients with either lymphoma or chronic leukemia had better survival than those with carcinoma or sarcoma (median survival 102 vs 12 weeks, p < 0.0001) with a 46% vs 3% 5-year survival, p < 0.0001). Echoguided pericardiocentesis with extended pericardial catheter placement is safe and effective in cancer patients with pericardial effusions. However, overall outcomes are poor in cancer patients with pericardial effusions that required drainage, particularly in those with carcinoma or sarcoma., (Copyright © 2018.

Foreign body ingestion is one of the many potential causes of esophageal perforation. In this case report we describe a man who presented with chest pain and was found to have an isolated hemorrhagic pericardial effusion secondary to occult ingestion and pericardial migration of a metallic foreign body. Surgical management was successful, and the patient has recovered well., (Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

One of the most common causes of pericardial effusion in the Western world is malignancy. Emergency physicians must maintain vigilance in suspecting pericardial effusion and tamponade in patients with known or suspected malignancy who present with tachycardia, dyspnea, and hypotension. Diagnosis can be expedited by key physical examination, electrocardiogram, and sonographic findings. Unstable or crashing patients with tamponade must undergo emergent pericardiocentesis for removal of fluid and pressure to restore cardiac output., (Copyright © 2018 Elsevier Inc.

Background: Pericardial effusion (PE) is a common finding in patients who have chronic cardiac failure, who had undergone cardiac surgery, or who have certain other benign and malignant diseases. Pericardial drainage procedures are often requested for both diagnostic and therapeutic purposes. The perceived benefit is that it allows for diagnosis of malignancy or infection for patients with PEs of unclear etiology. The purpose of the study is to determine the diagnostic yield of surgical drainage procedures., Methods: We conducted a retrospective chart review of patients who underwent surgical drainage procedures of PEs from July 1st, 2011 to January 1st, 2017 at a single institution. The variables included data on preoperative, intraoperative, and postoperative findings; morbidity; and survival., Results: A total of 145 patients with an average age of 61 ± 5 and primarily men (53%) were evaluated. All of the surgical drainage procedures were performed through the sub-xiphoid approach. Twenty-five of the 145 patients (17.2%) had diagnostic findings in either the pericardial tissue or fluid. The cytology alone was diagnostic in 4.8% (N = 7) of patients with mixed findings including adenocarcinoma of the lung and breast. The pathology was diagnostic for cancer in 1.4% (N = 2) of patients with Melanoma and Lung cancer identified. The cytology and pathology were concordant in 4.0% (N = 6) identifying cancers that included mesothelioma and adenocarcinoma. Infection was identified in the pericardial fluid in 6.9% (N = 10) of the patients., Conclusion: Surgical pericardial drainage procedures allow for removal of PE that may lead to tamponade physiology and potential mortality. Although there is therapeutic benefit from these procedures there is only a small diagnostic benefit.

A 72-year-old Chinese man presented with mild symptoms of heart failure. Transthoracic echocardiography showed signs of cardiac tamponade though clinically he was relatively well. The option of pericardiocentesis was not carried out due to a narrow window for aspiration with only a thin layer of effusion seen surrounding the apex and right ventricle on subcostal view.Pericardial window was done via a left anterolateral thoracotomy. Intraoperatively, 500 cm 3 of purulent fluid was drained. Microbiology screens were all negative. We present the atypical clinical course of this elderly man presenting with a large pyopericardium., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2018.

: Pericardiocentesis is a valuable technique for the diagnosis and treatment of patients with pericardial effusion and cardiac tamponade, although it may be associated with potentially serious complications. Through the years, many different imaging approaches have been described to reduce the complication rate of the procedure. This systematic review provides a focused overview of the different techniques developed in recent years to reduce the procedural complications and to increase the related success rate.

Subacute tamponade is a challenging diagnosis requiring careful consideration of both clinical and imaging data. We aimed at exploring the association of initial blood pressure with markers of pericardial effusion severity in patients with moderate and large pericardial effusion. We conducted a retrospective, single-center study in 102 well-phenotyped patients with moderate and large pericardial effusion. The presenting systolic and diastolic blood pressure recordings were divided into tertiles to examine the association between the blood pressure and the different established markers of pericardial effusion severity. On presentation, 42% of patients had systolic blood pressure exceeding 130 mm Hg, and only 5% of patients had systolic blood pressure <90 mm Hg. Patients in the lowest blood pressure tertiles did not differ significantly from patients in the upper tertiles in terms of clinical, etiologic, or echocardiographic characteristics. Although patients who underwent pericardial drainage had higher presenting heart rates, no significant differences were seen in the blood pressure recordings, either systolic or diastolic (mean 125 mm Hg vs 130 mm Hg, p = 0.36 and 76 vs 75 mm Hg, p = 0.82, respectively). In conclusion, systolic and diastolic blood pressure recordings upon initial presentation do not demonstrate a significant association with markers of effusion severity or the need for drainage in patients with moderate and large pericardial effusion., (Copyright © 2018 Elsevier Inc.

Background Percutaneous device closure of an ostium secundum atrial septal defect is associated with excellent outcomes and cosmetic results but at the cost of occasional serious and sometimes fatal complications as well as lifelong follow-up. Surgical intervention is required in cases of device-related complications, which carries a slightly higher risk compared to primary closure of an atrial septal defect. We present a surgical perspective of device closure of atrial septal defect. Methods Our database was searched over 4 years for complications related to percutaneous device closure of atrial septal defect, which required surgical retrieval of the device and closure of the defect. We identified 14 cases that required surgical intervention. Results The median age of the 14 patients was 18 years (range 4-58 years). The size of the defect ranged from 15 to 40 mm (median 30 mm). Device embolization into any part of the cardiovascular system ( n = 8) was the most common complication, followed by malalignment of the device ( n = 5). One patient had left atrial appendage perforation causing pericardial effusion and cardiac tamponade, and underwent surgical repair. The other 13 patients underwent removal of the device and atrial septal defect closure. One patient developed severe mitral regurgitation requiring mitral valve replacement. There was no mortality. Conclusion Although the incidence of device-related complications may be small, they carry a high risk of death or long-term morbidity, even with a small atrial septal defect, unlike primary surgical closure of isolated atrial septal defect.

The intra-pericardial paraganglioma is very rare and most of them present with hypertension or palpitations. Here we reported an extraordinarily rare case of intra-pericardial paraganglioma presenting as faint, pitting edema, abdominal fullness with ascites, and hemopericardium with impending tamponade, which was treated successfully by emergent pericardiocentesis and surgical resection.
