Pericardial Disease in Cancer Patients

A review of cardioprotective effect of ginsenosides in chemotherapy-induced cardiotoxicity

Chemotherapy-induced cardiotoxicity is a significant concern in cancer treatment, as certain chemotherapeutic agents can have adverse effects on the cardiovascular system. This can lead to a range of cardiac complications, including heart failure, arrhythmias, myocardial dysfunction, pericardial complications, and vascular toxicity. Strategies to mitigate chemotherapy-induced cardiotoxicity may include the use of cardioprotective agents (e.g., dexrazoxane), dose adjustments, alternative treatment regimens, and the implementation of preventive measures, such as lifestyle modifications and the management of cardiovascular risk factors. Ginsenosides, the active compounds found in ginseng (Panax ginseng), have been studied for their potential cardioprotective effects in the context of chemotherapy-induced cardiotoxicity. In this review, we investigate the cardioprotective effect of ginsenosides in chemotherapy-induced cardiotoxicity. Ginsenosides have been shown to possess potent antioxidant properties, which can help mitigate the oxidative stress and inflammation associated with chemotherapy-induced cardiac injury. They can modulate the expression of antioxidant enzymes and reduce the production of reactive oxygen species, thereby protecting cardiomyocytes from damage. Ginsenosides can also inhibit apoptosis (programmed cell death) of cardiomyocytes, which is a key mechanism underlying chemotherapy-induced cardiotoxicity. Modulation of ion channels, improvement of lipid profiles, anti-platelet and anti-thrombotic effects, and promotion of angiogenesis and neovascularization are another important mechanisms behind potential effects of ginsenosides on cardiovascular health. Ginsenosides can improve various parameters of cardiac function, such as ejection fraction, fractional shortening, and cardiac output, in animal models of chemotherapy-induced cardiotoxicity. The cardioprotective effects of ginsenosides have been observed in preclinical studies using various chemotherapeutic agents, including doxorubicin, cisplatin, and 5-fluorouracil. However, more clinical studies are needed to fully elucidate the therapeutic potential of ginsenosides in preventing and managing chemotherapy-induced cardiotoxicity in cancer patients.

Cardiooncology in the ICU - Cardiac Urgencies in Cancer Care

Cardiovascular disease is an increasing risk of morbidity and mortality in cancer patients, related to an growing number of aging survivors with pre-existing cardiovascular disease and the use of traditional and novel cancer therapies with cardiotoxic effects. While many cardiac complications are chronic processes that develop over time, there are many acute processes that may arise in hospitalized patients. It is important for hospitalists and critical care physicians to be familiar with the recognition and management of these conditions in this unique population. This article reviews the presentation and management of common cardiac urgencies in critically ill cancer patients including acute decompensated heart failure, acute coronary syndromes, arrhythmias, hypertensive crises, pulmonary embolism, pericardial tamponade and myocarditis.

Risk factors associated with clinically relevant pericardial effusion after primary cardiac implantable electronic device implantation

INTRODUCTION

Pericardial effusion, a known complication to implantation of cardiac implantable electronic devices (CIED), may cause life-threatening cardiac tamponade. Limited knowledge is available about risk factors for clinically relevant procedural pericardial effusion. The aim is to identify the patient- and procedure-related risk factors associated with clinically relevant procedural pericardial effusion.

METHOD

A nationwide observational cohort study based on data on 55 121 patients from the Danish Pacemaker Register between 2000 and 2018. We defined a clinically relevant procedural pericardial effusion related to the implantation if it occurred within 90 days after the primary CIED-procedure. Prespecified risk factors were analysed by multivariable logistic regression models to estimate the association with pericardial effusion.

RESULTS

There were 115 (0.21%) patients diagnosed with clinically relevant procedural pericardial effusion, with a median age of 75 years and 38.3% were females. Of these, 80.9% lead to a subsequent pericardiocentesis procedure. In adjusted logistic regression analysis, an increased risk of clinically relevant pericardial effusion was associated with female sex (OR:1.49 [95%CI: 1.03-2.16]), heart failure (OR:1.54 [95%CI: 1.06-2.23]), previous cardiac surgery (OR:1.63 [95%CI: 1.05-2.55]), CRT-device (OR:2.05 [95%CI: 1.23-3.41]), tertiary-centres (OR:1.8 [95%CI: 1.18-2.73]), increased procedural volume per year (>1000) (OR:1.85 [95%CI: 1.03-3.30]), indication of device-implantation (atrioventricular block) (OR:2.37 [95CI: 1.45-3.87]), and increasing number of leads implanted (two leads (OR:2.39 [95%CI: 1.43-4.00]), three leads (OR:4.77 [95%CI: 2.50-9.10])).

CONCLUSION

Clinically relevant procedural pericardial effusion is a rare complication after CIED-implantation in Denmark. This study reveals important patient- and procedure-related risk factors associated with clinically relevant procedural pericardial effusion.

An integrative analysis to identify pancancer epigenetic biomarkers

Integrating and analyzing the pancancer data collected from different experiments is crucial for gaining insights into the common mechanisms in the molecular level underlying the development and progression of cancers. Epigenetic study of the pancancer data can provide promising results in biomarker discovery. The genes that are epigenetically dysregulated in different cancers are powerful biomarkers for drug-related studies. This paper identifies the genes having altered expression due to aberrant methylation patterns using differential analysis of TCGA pancancer data of 12 different cancers. We identified a comprehensive set of 115 epigenetic biomarker genes out of which 106 genes having pancancer properties. The correlation analysis, gene set enrichment, protein-protein interaction analysis, pancancer characteristics analysis, and diagnostic modeling were performed on these biomarkers to illustrate the power of this signature and found to be important in different molecular operations related to cancer. An accuracy of 97.56% was obtained on TCGA pancancer gene expression dataset for predicting the binary class tumor or normal.

Pericardial Disease in Patients with Cancer: Clinical Insights on Diagnosis and Treatment

Pericardial disease is increasingly recognized in cancer patients, including acute pericarditis, pericardial effusion, and constrictive pericarditis, often indicating a poor prognosis. Acute pericarditis arises from direct tumor involvement, cancer therapies, and radiotherapy. Immune checkpoint inhibitor (ICI)-related pericarditis, though rare, entails significant mortality risk. Treatment includes NSAIDs, colchicine, and corticosteroids or anti-IL1 drugs in refractory cases. Pericardial effusion is the most frequent manifestation, primarily caused by lung cancer, followed by breast cancer, lymphoma, leukemia, gastrointestinal tumors, and melanoma. Chemotherapy, immunotherapy, and radiotherapy may also cause fluid accumulation in the pericardial space. Symptomatic relief for pericardial effusion may require pericardiocentesis, prolonged catheter drainage, or a pericardial window. Instillation of intrapericardial cytostatic agents may reduce recurrence. Constrictive pericarditis, though less common, often develops from radiotherapy and requires multimodality imaging for diagnosis, with pericardiectomy as the definitive treatment. Primary pericardial tumors are rare, with metastases being more frequent. Patients with cancer and pericardial disease generally have poor survival, emphasizing the need for early detection. A multidisciplinary approach involving hematologists, oncologists, and cardiologists is crucial to tailoring pericardial disease treatment to a patient's clinical status, thereby improving the quality of life and prognosis.

Malignant Pericardial Effusion: A Systematic Review

Background

Malignant pericardial effusion (Eff) is often asymptomatic and has an unknown prevalence, due to its occult presentation. The condition often is identified postmortem on autopsy, and it is associated with a poor prognosis. Given the late presentation of malignant pericardial Effs, a minimal volume of literature has examined the epidemiology, clinical characteristics, and outcomes of these complex patients. We conducted a systematic review to advance present understanding of this condition.

Methods

A search of 4 databases resulted in 41 case reports meeting criteria. Inclusion criteria were being a patient aged > 18 years who presented with pericardial Eff in the setting of malignancy. Intervention was medical and/or surgical therapy, and the outcome was mortality.

Results

For the 41 patients included, the median age was 54 years, and the majority were male patients (58%). Dyspnea was the leading symptom (90%), and cardiac tamponade was present in 78% of cases. Common cancers included lung, gastrointestinal, and renal neoplasms (59%). Pericardiocentesis occurred in 98% of cases, with a median fluid extraction volume of 1000 mL. Death occurred in 44%, primarily due to disease progression and/or metastasis.

Conclusions

This study presents the largest systematic review on malignancy-induced pericardial Effs to date. Notably, solid tumours, and specifically lung adenocarcinomas, are common culprits. Malignant pericardial Effs are often severe, with a majority of patients presenting with cardiac tamponade. Overall, treatment options are limited, and the associated mortality rate is high.

Pericardiocentesis versus window formation in malignant pericardial effusion: trends and outcomes

OBJECTIVES

Malignant pericardial effusion (MPE) in patients with cancer is associated with poor prognosis. This study aimed to compare clinical outcomes in patients with cancer who underwent pericardiocentesis versus pericardial window formation.

METHODS

In the present study, 765 consecutive patients with cancer (mean age 58.4 years, 395 men) who underwent pericardial drainage between 2003 and 2022 were retrospectively analysed. All-cause death and MPE recurrence were compared based on the drainage method (pericardiocentesis vs pericardial window formation) and time period (period 1: 2003-2012; period 2: 2013-2022).

RESULTS

Pericardiocentesis was performed in 639 (83.5%) patients and pericardial window formation in 126 (16.5%). There was no difference in age, sex distribution, proportion of metastatic or relapsed cancer, and chemotherapy status between the pericardiocentesis and pericardial window formation groups. Difference was not found in all-cause death between the two groups (log-rank p=0.226) regardless of the period. The pericardial window formation group was associated with lower MPE recurrence than the pericardiocentesis group (6.3% vs 18.0%, log-rank p=0.001). This advantage of pericardial window formation was more significant in period 2 (18.1% vs 1.3%, log-rank p=0.005). In multivariate analysis, pericardial window formation was associated with lower MPE recurrence (HR: 0.31, 95% CI: 0.15 to 0.63, p=0.001); younger age, metastatic or relapsed cancer, and positive malignant cells in pericardial fluid were associated with increased recurrence.

CONCLUSION

In patients undergoing pericardial drainage for MPE, pericardial window formation showed mortality outcomes comparable with pericardiocentesis and was associated with lower incidence of MPE recurrence.

"A Double Twist" Presentation - A Case Report of Purulent Cardiac Tamponade following a Rare Complication of Small-Cell Lung Cancer Radiotherapy

Background

Small cell lung cancer is an aggressive tumor with a poor prognosis that requires prompt treatment. While radiotherapy may enhance survival when superior vena cava syndrome is present, radiation therapy-induced pericardial disease can be a potential complication.

Case Report

A 55-year-old man, who recently underwent radiotherapy for stage IV small-cell lung cancer complicated by superior vena cava syndrome, presented with chest pain and dyspnea. In the emergency room, he was dyspneic, hypotensive, and tachycardic. Pulmonary auscultation revealed the absence of lung sounds on the right. The initial electrocardiogram showed ST-segment elevation in lateral leads and in lead DII, with reciprocal changes in lead DIII. A bedside transthoracic echocardiogram revealed cardiac tamponade and emergent pericardiocentesis was performed, removing 500 ml of purulent fluid, resulting in an immediate clinical improvement. Thoracentesis was also performed, showing no empyema. Large spectrum empirical antibiotic therapy was started. Cultures from the pericardial fluid and peripheral blood grew multi-sensitive Streptococcus pneumoniae. Cytological analysis of the pericardial fluid was consistent with infection. The patient improved after 2 weeks of targeted antibiotic therapy and underwent the first cycle of chemotherapy. He was discharged with an early scheduled pulmonology appointment.

Conclusions

Although the most common causes of pericardial effusion in lung cancer are malignant, non-malignant etiologies should also be considered. This patient had an infectious pericardial effusion most probably due to a pericardial-mediastinal mass fistula caused by radiotherapy. This was a diagnostic challenge, both in the emergency room as well in the inpatient setting.

LEARNING POINTS

Small cell lung cancer is a fast-growing cancer that exhibits aggressive behavior.In patients with lung cancer, malignant pericardial effusions are more common than non-malignant ones.Purulent pericardial effusions, especially those due to lung cancer, are rare in developed countries with very few reports in the literature.

The BALTO Registry: Long-term results of percutaneous BALloon pericardioTomy in oncological patients

OBJECTIVES

The aim of this study was to analyze the efficacy and safety of percutaneous balloon pericardiotomy (PBP) in oncological patients who present with a malignant pericardial effusion (MPE).

BACKGROUND

The use of PBP as a treatment for MPE is not standardized due to the limited evidence. Furthermore, the performance of a second PBP for a recurrence after a first procedure is controversial.

METHODS

The BALTO Registry (BALloon pericardioTomy in Oncological patients) is a prospective, single-center, observational registry that includes consecutive PBP performed for MPE from October 2007 to February 2022. Clinical and procedural, characteristics, as well as clinical outcome were analyzed.

RESULTS

Seventy-six PBP were performed in 61 patients (65% female). Mean age was of 66.4 ± 11.2 years. In 15 cases, a second PBP procedure was performed due to recurrence despite the first PBP. The procedure could be performed effectively in all cases with only two serious complications. Ninety-five percent of cases were discharged alive from the hospital. During a median follow-up of 6.3 months (interquartile range [IQR], 0.9-10.8), MPE recurred in 24.5% cases although no recurrences were reported after the second procedure. No evidence of malignant pleural effusion developed on follow-up. The median overall survival time was 5.8 months (IQR, 0.8-10.2) and the time to recurrence after the first PBP was 2.4 months (IQR, 0.7-4.5).

CONCLUSIONS

PBP is a safe and effective treatment for MPE. It could be considered an acceptable therapy in most MPE, even in those who recur after a first procedure.

Developing Cardio-Oncology Programs in the New Era: Beyond Ventricular Dysfunction Due to Cancer Treatments

Cardiovascular disease is a common problem in cancer patients that is becoming more widely recognized. This may be a consequence of prior cardiovascular risk factors but could also be secondary to the anticancer treatments. With the goal of offering a multidisciplinary approach to guaranteeing optimal cancer therapy and the early detection of related cardiac diseases, and in light of the recent ESC Cardio-Oncology Guideline recommendations, we developed a Cardio-Oncology unit devoted to the prevention and management of these specific complications. This document brings together important aspects to consider for the development and organization of a Cardio-Oncology program through our own experience and the current evidence.

Cardiovascular Toxicities of Radiation Therapy and Recommended Screening and Surveillance

Radiation therapy is a key part of treatment for many cancers. Vast advancements in the field of radiation oncology have led to a decrease in malignancy-related mortality, which has uncovered some of the long-term side effects of radiation therapy. Specifically, there has been an increase in research looking into the cardiovascular side effects of chest radiation therapy for cancers of the esophagus, breast, and lung tissue as well as lymphomas. The manifestations of cardiac injury from irradiation range from short-term complications, such as pericarditis, to long-term damage including cardiomyopathy, valvular disease, and conduction disturbances. The aims of this article are to describe the cardiovascular side effects and the associated risk factors, to discuss risk reduction strategies, and to provide guidance in pre-radiation screening, post-radiation surveillance, and the management of these conditions.

Radiation-Induced Pericardial Disease: Mechanisms, Diagnosis, and Treatment

PURPOSE OF REVIEW

We aim to give a concise overview of the different clinical manifestations of both acute and long-term radiotherapy-related pericardial diseases, the underlying pathophysiology as well as the diagnosis and treatment options.

RECENT FINDINGS

Radiotherapy-related pericardial disease is common, but despite radiotherapy being a cornerstone of many cancer treatments, this disease entity is relatively underrepresented in clinical trials, resulting in a paucity of research data on pathophysiology and management. Since the development of innovative cancer treatments, survival has significantly improved. Therefore, the importance of long-term treatment-related side effects increases, most notably cancer treatment-related cardiovascular toxicity. In patients undergoing radiotherapy as a part of their cancer treatment, radiotherapy-related pericardial disease can manifest early (during or shortly after radiotherapy administration) or very late (several years to decades after treatment). This exceptionally long latency period confronts physicians with treatment-related side effects of radiotherapy regimens that may have been abandoned already.

A Rare Case of Non-Small-Cell Lung Carcinoma Complicated by Massive Pericardial Effusion and Cardiac Tamponade: A Case Report

This case report presents a late middle-aged man with a right infra-hilar lung mass and pericardial effusion (PE). The patient was diagnosed with metastatic small-cell lung carcinoma, with metastases to the liver, pancreas, and cerebellum. The pericardial fluid cytology confirmed the presence of malignant cells most compatible with non-small-cell carcinoma. The patient received carbo/etoposide chemotherapy, and his treatment plan included adding atezolizumab and radiation therapy. Despite the excellent efficacy of immunotherapy, immune-related adverse events (IRAEs), including cardiac toxicity, were noted in some patients. PE related to immune checkpoint inhibitor (ICI) use is rare but potentially severe. This case highlights the importance of vigilant monitoring for cardiovascular symptoms during immunotherapy and the significance of pericardial fluid analysis in diagnosing malignant pericardial disease. Prompt diagnosis and appropriate treatment can lead to improved patient outcomes in cases of lung cancer-associated cardiac complications.

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.

Dyspnea in Oncological Patients: a Brain Teaser

Dyspnea is one of the most common symptoms in oncological patients with greater prevalence in lung cancer and advanced disease states. Causes of dyspnea can be directly or indirectly associated with cancer, anti-neoplastic therapies and comorbidities unrelated to cancer. Routine screening of dyspnea is suggested for all oncological patients by using unidimensional, simple scales and multidimensional tools to capture more domains affected by this symptom and to assess the effectiveness of interventions. The first step in the treatment algorithm of dyspnea is the identification of potentially reversible causes; if no specific cause is depicted, symptomatic treatment with non-pharmacological and pharmacological interventions is suggested. Referral to palliative care and continuous palliative sedation are the last resort in patients with a very limited life expectancy of not more than a few days for symptomatic relief and to decrease of the distress of patients and caregivers.

Cardiogenic shock among cancer patients

Sophisticated cancer treatments, cardiovascular risk factors, and aging trigger acute cardiovascular diseases in an increasing number of cancer patients. Among acute cardiovascular diseases, cancer treatment, as well as the cancer disease itself, may induce a cardiogenic shock. Although increasing, these cardiogenic shocks are still relatively limited, and their management is a matter of debate in cancer patients. Etiologies that cause cardiogenic shock are slightly different from those of non-cancer patients, and management has some specific features always requiring a multidisciplinary approach. Recent guidelines and extensive data from the scientific literature can provide useful guidance for the management of these critical patients. Even if no etiologic therapy is available, maximal intensive supportive measures can often be justified, as most of these cardiogenic shocks are potentially reversible. In this review, we address the major etiologies that can lead to cardiogenic shock in cancer patients and discuss issues related to its management.

Mechanisms of Myocardial Ischemia in Cancer Patients: A State-of-the-Art Review of Obstructive Versus Non-Obstructive Causes

In patients with cancer, myocardial infarction (MI) has distinct features and mechanisms compared to the non-oncology population. Triggers of myocardial ischemia specific to the oncology population have been increasingly identified. Coronary plaque disruption, coronary vasospasm, coronary microvascular dysfunction, spontaneous coronary artery dissection, and coronary oxygen supply-demand mismatch are all causes of MI that have been shown to have specific triggers related to either the treatments or complications of cancer. MI can occur in the presence or absence of atherosclerotic coronary artery disease (CAD). MI with nonobstructive CAD (MINOCA) is a heterogeneous syndrome that has distinct pathophysiology and different epidemiology from MI with significant CAD (MI-CAD). Recognition and differentiation of MI-CAD and MINOCA is essential in the oncology population, due to unique etiology and impact on diagnosis, management, and overall outcomes. There are currently no reports in the literature concerning MINOCA as a unified syndrome in oncology patients. The purpose of this review is to analyze the literature for studies related to known triggers of myocardial ischemia in cancer patients, with a focus on MINOCA. We propose that certain cancer treatments can induce MINOCA-like states, and further research is warranted to investigate mechanisms that may be unique to certain cancer states and types of treatment.

Chest Pain in the Cancer Patient

Chest pain is one of the most common presenting symptoms in patients seeking care from a physician. Risk assessment tools and scores have facilitated prompt diagnosis and optimal management in these patients; however, it is unclear as to whether a standardised approach can adequately triage chest pain in cancer patients and survivors. This is of concern because cancer patients are often at an increased risk of cardiovascular mortality and morbidity given the shared risk factors between cancer and cardiovascular disease, compounded by the fact that certain anti-cancer therapies are associated with an increased risk of cardiovascular events that can persist for weeks and even years after treatment. This article describes the underlying mechanisms of the most common causes of chest pain in cancer patients with an emphasis on how their management may differ to that of non-cancer patients with chest pain. It will also highlight the role of the cardio-oncology team, who can aid in identifying cancer therapy-related cardiovascular side-effects and provide optimal multidisciplinary care for these patients.

Immunomodulating Therapies in Acute Myocarditis and Recurrent/Acute Pericarditis

The field of inflammatory disease of the heart or "cardio-immunology" is rapidly evolving due to the wider use of non-invasive diagnostic tools able to detect and monitor myocardial inflammation. In acute myocarditis, recent data on the use of immunomodulating therapies have been reported both in the setting of systemic autoimmune disorders and in the setting of isolated forms, especially in patients with specific histology (e.g., eosinophilic myocarditis) or with an arrhythmicburden. A role for immunosuppressive therapies has been also shown in severe cases of coronavirus disease 2019 (COVID-19), a condition that can be associated with cardiac injury and acute myocarditis. Furthermore, ongoing clinical trials are assessing the role of high dosage methylprednisolone in the context of acute myocarditis complicated by heart failure or fulminant presentation or the role of anakinra to treat patients with acute myocarditis excluding patients with hemodynamically unstable conditions. In addition, the explosion of immune-mediated therapies in oncology has introduced new pathophysiological entities, such as immune-checkpoint inhibitor-associated myocarditis and new basic research models to understand the interaction between the cardiac and immune systems. Here we provide a broad overview of evolving areas in cardio-immunology. We summarize the use of new imaging tools in combination with endomyocardial biopsy and laboratory parameters such as high sensitivity troponin to monitor the response to immunomodulating therapies based on recent evidence and clinical experience. Concerning pericarditis, the normal composition of pericardial fluid has been recently elucidated, allowing to assess the actual presence of inflammation; indeed, normal pericardial fluid is rich in nucleated cells, protein, albumin, LDH, at levels consistent with inflammatory exudates in other biological fluids. Importantly, recent findings showed how innate immunity plays a pivotal role in the pathogenesis of recurrent pericarditis with raised C-reactive protein, with inflammasome and IL-1 overproduction as drivers for systemic inflammatory response. In the era of tailored medicine, anti-IL-1 agents such as anakinra and rilonacept have been demonstrated highly effective in patients with recurrent pericarditis associated with an inflammatory phenotype.

Recent advances in pericarditis

Pericardial diseases are an heterogeneous group of entities, ranging from acute pericarditis to asymptomatic pericardial effusions. New advances in understanding the processes underlying them have been made. In 2020 a prospective study defined the reference intervals of the component of normal pericardial fluid, that was found to be rich in nucleated cells, proteins, albumin and LDH, at levels compatible with the inflammatory exudates of other biological fluids such as pleural or peritoneal fluid; Light's criteria should not be used to evaluate it. Recently we also analyzed systematically large chronic idiopathic non-inflammatory pericardial effusions, observing that a non-invasive wait-and-see approach may be the best choice in clinical practice in oligosymptomatic cases. Concerning acute recurrent pericarditis (RP), an innovative interaction between cardiologists, internists and pediatric rheumatologists led to the intuition of a pivotal role of IL-1 in recurrent pericarditis characterized by an evident inflammatory recurrent phenotype, and recent data have shown the striking efficacy of anakinra and rilonacept in these patients. The proper selection of the patient is important; the ideal candidate for anti-IL-1 therapy is the patient with RP with high levels of serum C-reactive protein, high fever, neutrophil leukocitosis, pleuropulmonary involvement, frequent exacerbations and resistant to conventional therapy. On the contrary, anti-IL-1 drugs are not indicated in patients with pericardial effusion whose cause is not attributable to inflammatory phenomena. Finally, many patients with RP are women of childbearing age, and the possibility for these women to become pregnant must be addressed by multidisciplinary teams.

Recurrence of pericardial effusion after different procedure modalities in patients with non-small-cell lung cancer

Background

Lung cancer with related pericardial effusion is not rare. Intervention is a crucial step for symptomatic effusion. It is unknown, however, whether the different invasive interventions for pericardial effusion result in different survival outcomes. This study analyzed the clinical characteristics and prognostic factors for patients with non-small-cell lung cancer (NSCLC) who have undergone different procedures.

Methods

From January 2006 to June 2018, we collected data from patients with NSCLC who have received invasive intervention for pericardial effusions. The patients were divided into three categories: simple pericardiocentesis, balloon pericardiotomy, and surgical pericardiectomy. Kaplan–Meier curve and log-rank test were used to analyze the pericardial effusion recurrence-free survival (RFS) and overall survival (OS).

Results

A total of 244 patients were enrolled. Adenocarcinoma (83.6%) was the major NSCLC subtype. Invasive intervention, including simple pericardiocentesis, balloon pericardiotomy, and surgical pericardiectomy, had been carried out on 52, 170, and 22 patients, respectively. The 1-year RFS rates in simple pericardiocentesis, balloon pericardiotomy, and surgical pericardiectomy were 19.2%, 31.2%, and 31.8%, respectively (P = 0.128), and the median RFS was 1.67, 5.03, and 8.32 months, respectively (P = 0.008). There was no significant difference in OS, however, with the median OS at 1.67, 6.43, and 8.32 months, respectively (P = 0.064). According to the multivariable analysis, the gravity in pericardial fluid analysis, receiving systemic therapy after pericardial effusion, and the time period from stage IV lung cancer to the presence of pericardial effusion were independent prognostic factors for pericardial effusion RFS and OS.

Conclusions

Patients who have undergone simple pericardiocentesis alone for the management of NSCLC-related pericardial effusion have lower 1-year RFS rates than those who have undergone balloon pericardiotomy and surgical pericardiectomy. Therefore, balloon pericardiotomy and surgical pericardiectomy should be carried out for patients with NSCLC-related pericardial effusion if tolerable.

•

This is the first study to compare the three common procedures to manage NSCLC-related pericardial effusion.

•

Simple pericardiocentesis group had lower 1-year RFS rate than balloon pericardiotomy or surgical pericardiectomy group.

•

Surgical pericardiectomy as management demonstrated an improving OS trend.

Cardiac Computed Tomography in Cardio-Oncology: JACC: CardioOncology Primer

Cancer patients and survivors have elevated cardiovascular risk when compared with noncancer patients. Cardio-oncology has emerged as a new subspecialty to comanage and address cardiovascular complications in cancer patients such as heart failure, atherosclerotic cardiovascular disease (ASCVD), valvular heart disease, pericardial disease, and arrhythmias. Cardiac computed tomography (CT) can be helpful in identifying both clinical and subclinical ASCVD in cancer patients and survivors. Radiation therapy treatment planning CT scans and cancer staging/re-staging imaging studies can quantify calcium scores which can identify pre-existing subclinical ASCVD. Cardiac CT can be helpful in the evaluation of cardiac tumors and pericardial diseases, especially in patients who cannot tolerate or have a contraindication to cardiac magnetic resonance. In this review, we describe the optimal utilization of cardiac CT in cancer patients, including risk assessment for ASCVD and identification of cancer treatment-related cardiovascular toxicity.

Thymic cancer: A not-so-indolent cause of pericardial effusion

The incidence of pericardial effusion in the U.S. is roughly 3.4% [1]. While most causes of pericardial effusions are indolent and transient, malignancy is a much more insidious cause that cannot be overlooked. Most cases of documented pericardial effusion secondary to malignancy have been due to mass effect from benign thymic tumors, such as thymomas. Our case highlights a 41-year-old male who presented with a dry cough and epigastric pain, found to have a large pericardial effusion and incidental thymic mass. The mass was biopsied and found to be keratinizing squamous cell carcinoma. This case expands our knowledge base as clinicians that pericardial effusions can be caused by malignant extension of tumors, rather than simply by mass effect of benign tumors.

Acute pericarditis, Graves' disease, and thymic hyperplasia: a case report

BACKGROUND

Acute pericarditis as a sign of mediastinal mass is rare and aetiological diagnosis can be challenging without adequate imaging.

CASE SUMMARY

An 18-year-old woman came to our attention describing acute sharp chest pain radiated to the left arm, exacerbated with supine positioning and attenuated while sitting or leaning forward. The electrocardiogram showed diffuse ST elevation and PR depression, with sinus tachycardia. Cardiac biomarkers and D-dimer were negative; echocardiography showed no abnormalities and the absence of pericardial effusion. Her blood work revealed no sign of inflammation or bacterial infection (PCR and procalcitonin were normal); thyroid-stimulating hormone plasma levels were suppressed, showing decompensated thyrotoxicosis. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), Epstein-Barr virus, human immunodeficiency virus, hepatitis C virus, Enterovirus, Parvovirus B19, and Adenovirus tests were normal. Her past medical history was silent, apart from Grave's disease on treatment with methimazole. Chest computed tomography (CT) was performed and showed the presence of slightly increased density pericardial effusion, with a maximum thickness of 15 mm in the upper mediastinum. Finally, cardiac magnetic resonance (MR) identified a mass of 73 × 51 mm located in the upper mediastinum. The mass was subsequently biopsed with video-assisted thoracoscopic surgery and the histological analysis showed thymic hyperplasia.

DISCUSSION

This case shows the importance of an adequate clinical suspicion of thymic hyperplasia in the context of acute pericarditis symptoms and known Graves' disease. In this case, a negative chest CT finding may not be sufficient to rule out the diagnosis and cardiac MR imaging is necessary.

Cardiac computed tomography in cardio-oncology: an update on recent clinical applications

Chemotherapy and radiotherapy have drastically improved cancer survival, but they can result in significant short- and long-term cardiovascular complications, most commonly heart failure from chemotherapy, whilst radiotherapy increases the risk of premature coronary artery disease (CAD), valve, and pericardial diseases. Cardiac computed tomography (CT) with calcium scoring has a role in screening asymptomatic patients for premature CAD, cardiac CT angiography (CTCA) allows the identification of significant CAD, also in the acute settings where concerns exist towards invasive angiography. CTCA integrates the diagnostic work-up and guides surgical/percutaneous management of valvular heart diseases and allows the assessment of pericardial conditions, including detection of effusion and pericardial calcification. It is a widely available and fast imaging modality that allows a one-step evaluation of CAD, myocardial, valvular, and pericardial disease. This review aims to provide an update on its current use and accompanying evidence-base for cardiac CT in the management of cardio-oncology patients.

Fruquintinib beneficial in elderly patient with neoplastic pericardial effusion from rectal cancer: A case report

BACKGROUND

Neoplastic pericardial effusion (NPE) is a rare consequence of rectal cancer and carries a poor prognosis. Optimal management has yet to be determined. Fruquintinib is an oral anti-vascular endothelial growth factor receptor tyrosine kinase inhibitor approved by the China Food and Drug Administration in September 2018 as third-line treatment of metastatic colorectal cancer.

CASE SUMMARY

Herein, we report an elderly patient with NPE from rectal cancer who responded to the use of fruquintinib. In March 2015, a 65-year-old Chinese woman diagnosed with KRAS-mutated adenocarcinoma of the rectum was subjected to proctectomy, adjuvant concurrent chemoradiotherapy, and adjuvant chemotherapy. By October 2018, a mediastinal mass was detected via computed tomography. The growth had invaded parietal pericardium and left hilum, displaying features of rectal adenocarcinoma in a bronchial biopsy. FOLFIRI and FOLFOX chemotherapeutic regimens were administered as first- and second-line treatments. After two cycles of second-line agents, a sizeable pericardial effusion resulting in tamponade was drained by pericardial puncture. Fluid cytology showed cells consistent with rectal adenocarcinoma. Single-agent fruquintinib was initiated on January 3, 2019, as a third-line therapeutic. Ten cycles were delivered before the NPE recurred and other lesions progressed. The recurrence-free interval for NPE was 9.2 mo, attesting to the efficacy of fruquintinib. Ultimately, the patient entered a palliative care unit for best supportive care.

CONCLUSION

Fruquintinib may confer good survival benefit in elderly patients with NPEs due to rectal cancer.

Advanced lung cancer presenting with malignant pericardial effusion

Irregular pericardial wall thickening, mediastinal lymph nodes, and pericardial fluid analysis are helpful to identify metastasis to the pericardium though it is a marker of advanced disease and poor prognosis.

Prognostic Factors and Overall Survival After Pericardiocentesis in Patients With Cancer and Thrombocytopenia

Background: Pericardiocentesis is an important diagnostic and therapeutic tool for cancer-associated pericardial effusion. Limited safety and outcomes data exists regarding the management of malignancy-related pericardial effusion in patients with thrombocytopenia.

Objectives: Our study aimed to analyze prognostic factors and overall survival (OS) after pericardiocentesis in thrombocytopenic cancer patients.

Methods and Results: A retrospective review of 136 thrombocytopenic cancer patients who underwent primary percutaneous pericardiocentesis was performed. Degree of thrombocytopenia was classified by platelet count recorded on day of pericardiocentesis: 75–149 × 10³ cells/μL (41%); 50–74 × 10³ cells/μL (10%); 25–49 × 10³ cells/μL (24%); <25 × 10³ cells/μL (25%). Median OS was 2.6 months and median follow-up was 37.4 months. Kaplan-Meier survival analysis showed significant OS differences among thrombocytopenia severity groups (p = 0.023), and worse OS with platelets <100 vs. ≥100 × 10³ cells/μL (p = 0.031). By univariate analysis, thrombocytopenia severity was associated with increased risk of death (HR 0.993; 95% CI 0.989–0.997; p = 0.002). Poor prognostic factors for OS were advanced cancer, malignant effusion, elevated international normalized ratio (INR), quantity of platelet transfusions, and platelet transfusion resistance. However, thrombocytopenia severity became insignificant for OS (p = 0.802), after adjusting for advanced cancer and INR.

Conclusions: For patients with malignancy-related large pericardial effusion and thrombocytopenia, pericardiocentesis is a feasible intervention and should be considered due to low complication rates. There is no absolute contraindication to pericardiocentesis in case of hemodynamic instability, even with severe thrombocytopenia.

Pericardial Involvement in Cancer

Despite the monumental advances in the diagnoses and therapeutics of malignancy, several cancer patients have presented with pericardial involvement, including acute pericarditis, constrictive pericarditis, and pericardial effusion. Multiple factors can contribute to acute pericarditis, including direct metastasis to the heart, pericardial hemorrhage, infections due to immunosuppression, and cancer therapies that include chemotherapy, immunotherapy, and radiation. Pericardial effusion, either due to cancer invasion or cancer treatment, is one of the most common incidental findings in cancer patients, which significantly worsens morbidity and mortality. If left untreated, pericardial effusion is known to cause complications such as pericardial tamponade. Constrictive pericarditis can be due to radiation exposure, chemotherapy, or is a sequela of a previous episode of acute pericarditis. In conclusion, early detection, prompt treatment, and understanding of pericardial diseases are necessary to help improve the quality of life of cancer patients, and we aim to summarize the knowledge of pericardial involvement in patients with cancer.

Management of acute and recurrent pericarditis in pregnancy

This review summarizes the currently available evidence on the management of acute and recurrent pericarditis during pregnancy, focusing on the safety of diagnostic procedures and treatment options for the mother and foetus. Family planning should be addressed in women with recurrent pericarditis of reproductive age and adjustment of therapy should be considered before a planned pregnancy. The treatment of pericarditis in pregnancy is similar to that for non-pregnant women but considers current knowledge on drug safety during pregnancy and lactation. The largest case series on this topic described 21 pregnancies with idiopathic recurrent pericarditis. Pregnancy should be planned in a phase of disease quiescence. Non-steroidal anti-inflammatory drugs can be used at high dosages until the 20th week of gestation (except low-dose aspirin 100 mg/die). Colchicine is allowed until gravindex positivity; after this period, administration of this drug during pregnancy and lactation should be discussed with the mother if its use is important to control recurrent pericarditis. Prednisone is safe if used at low-medium doses (2,5 - 10 mg/die). General outcomes of pregnancy in patients with pericarditis are good when the mothers are followed by a multidisciplinary team with experience in the field.

Neoplasia-Associated Pericarditis-Predictor of Cancer Progression?

Pericarditis may signal the presence of cancer, even in the absence of other clinical or paraclinical signs. Corollary, the following question arises: Could the discovery of a newly developed pericarditis be used in patients with known neoplasia as a marker of cancer progression? In an attempt to find an answer to this question, this two-centre study included 341 consecutive patients with a confirmed diagnosis of cancer and evidence of pericardial effusion at echocardiography and/or CT/MRI scan. The patients' data were collected retrospectively if they further fulfilled the following inclusion criteria: available medical data from confirmation of pericarditis until evidence of cancer progression or until at least 12 months without progression. The average age of the patients was 62.16 years (22-86 years), and the study comprised 44.28% males and 55.71% females. All types of the most common neoplasms were represented. The results showed that 85.33% of patients had cancer progression temporally linked to pericarditis. Of these, 41.64% had cancer progression within 18 months after the diagnosis of pericarditis with a median time to progression of 5.03 months, ranging from 0 to 17 months; 43.69% had progression within a maximum of 2 months before the diagnosis of pericarditis. Only 14.66% had no cancer progression during the observation period. We concluded that pericarditis could be a sensitive marker of cancer evolution that could be widely used as a follow-up investigation for cancer patients as a marker of progression or recidive.

Cardio-oncology for the general physician: 'old' and 'new' cardiovascular toxicities and how to manage them

Cardio-oncology is the care of cancer patients with cardiovascular disease. The need for a dedicated subspecialty emerged to address heart failure caused by drugs such as anthracyclines and anti-human epidermal growth factor receptor 2 (HER2) therapies, but over time has expanded into an exciting subspecialty with widening horizons. While still dealing with a lot of commonly recognised toxicities, such as heart failure, hypertension and coronary disease, new and revolutionary cancer therapies have been associated with challenging cardiovascular complications, requiring specialist input to manage effectively. Echocardiography is a key investigation, with advanced techniques such as three-dimensional and strain assessment allowing more accurate diagnosis and earlier detection of subtle changes. Cardiac magnetic resonance and biomarkers are useful adjuncts to aid diagnosis and management. With increasing cancer incidence and improved cancer survival rates, it is important that general cardiologists and physicians are aware of cardiac complications associated with cancer and how to manage them.

Graft-versus-host disease: a case report of a rare but reversible cause of constrictive pericarditis

Background 

Constrictive pericarditis (CP), although an uncommon cause of heart failure, requires specialist multidisciplinary input and multi-modality imaging to identify the underlying aetiology and treat potentially reversible causes.

Case summary 

We report the case of a 74-year-old gentleman referred for assessment of progressive exertional dyspnoea and peripheral oedema, 30 months following treatment of acute myeloid leukaemia with high-dose chemotherapy and allogeneic stem cell transplantation. Clinical examination and cardiac imaging revealed a small pericardial effusion and pericardial thickening with constrictive physiology; however, no aetiology was identified despite diagnostic pericardiocentesis. The patient required recurrent hospital admissions for intravenous diuresis, therefore, following multidisciplinary discussions, surgical partial pericardectomy was performed. Histology suggested graft-vs.-host disease (GvHD) and post-operatively, the patient improved clinically. Following immunomodulatory therapy with ruxolitinib for both pericardial and pulmonary GvHD, his functional status improved further with no subsequent hospital admissions.

Discussion 

Although pericardial disease in cancer patients is common, CP is unusual. Determining the underlying aetiology is important for subsequent management, and here, we describe the use of multi-modality imaging to diagnose a rare cause, GvHD, which responded to surgical treatment and immunomodulatory therapy.

Cardiac Interventional Procedures in Cardio-Oncology Patients

Comorbidities specific to the cardio-oncology population contribute to the challenges in the interventional management of patients with cancer and cardiovascular disease (CVD). Patients with cancer have generally been excluded from cardiovascular randomized clinical trials. Endovascular procedures may represent a valid option in patients with cancer with a range of CVDs because of their minimally invasive nature. Patients with cancer are less likely to be treated according to societal guidelines because of perceived high risk. This article presents the specific challenges that interventional cardiologists face when caring for patients with cancer and the modern tools to optimize care.

Radiobiological models in prediction of radiation cardiotoxicity

Coronary disease induced by previous radiotherapy is the most common cause of death among patients treated with radiotherapy for cancer. Risk factors that may affect the frequency and intensity of radiotherapy's cardiac toxicity are primarily the radiation dose and the volume of the heart exposed to radiation. The prolonged survival time of patients after radiotherapy, but also the intensive development of modern radiotherapy techniques results in the necessity of precise estimation of both tumor control probability, and the risk of normal tissue damage, thus the models describing the probability of complications in normal tissues have also been developed. The response from the cardiovascular system to high-dose radiation is known and associated with a pro-inflammatory response. However, the effect of low doses may be completely different because it induces an anti-inflammatory response. Also, there is no unambiguous answer to the question of whether RICD is a deterministic effect. Moreover, there is a lack of literature data on the use of known radiobiological models to assess the risk of cardiovascular complications. The models described are general and concerns any healthy tissue. Therefore, when planning treatment for patients, particular attention should be paid to the dose and area of ​​the heart to be irradiated.

Is there a role for remote ischemic conditioning in preventing 5-fluorouracil-induced coronary vasospasm?

Cardiac ischemia associated with chemotherapy has been linked to several anti-neoplastic agents and is multifactorial in etiology. Coronary artery vasospasm is one of the most commonly reported effects of cancer therapy that can lead to myocardial ischemia or infarction. The chemotherapy agent 5-fluorouracil (5-FU) or its oral pro-drug capecitabine can result in coronary vascular endothelial dysfunction causing coronary artery spasm, and possibly coronary thrombosis. These drugs have also been shown to be associated with myocardial infarction, malignant ventricular arrhythmias, heart failure, cardiogenic shock, and sudden death. The proposed mechanisms underlying cardiotoxicity induced by 5-FU are vascular endothelial damage followed by thrombus formation, ischemia secondary to coronary artery vasospasm, direct toxicity on myocardium, and thrombogenicity. There remains a pressing need to discover novel and effective therapies that can prevent or ameliorate 5-FU associated cardiotoxicity. To this point, promising overlap has been observed between proposed remote ischemic conditioning (RIC) cardioprotective mechanisms and 5FU-associated cardiotoxic cellular pathways. RIC, in which transient episodes of limb ischemia and reperfusion (induced by inflations and deflations of a pneumatic cuff placed on the upper arm or thigh), confer both cardioprotective and vasculoprotective effects, and may therefore prevent 5-FU coronary artery spasm/cardiotoxicity. In this review, we will be discussing the following potentially therapeutic aspects of RIC in ameliorating 5-FU associated cardiotoxicity: sequential phases of 5-FU cardiotoxicity as possible targets for dual windows of cardioprotection characteristic of RIC; protective effects of RIC on endothelial function and microvasculature in relation to 5-FU induced endothelial dysfunction/microvascular dysfunction; reduction in platelet activation by RIC in the context of 5-FU induced thrombogenicity; and the utility of improvement in mitochondrial function conferred by RIC in 5-FU induced cellular toxicity secondary to mitochondrial dysfunction.

Endometrial carcinoma complicated by malignant pericardial effusion: A case report on the therapeutic regimen

RATIONALE

High-stage endometrial carcinoma is an aggressive tumor with a high propensity for distant spread. However, metastases to the pericardium are rare in gynecological cancer, and are usually fatal.

PATIENT CONCERNS

A 69-year-old woman was diagnosed with endometrial carcinoma with pericardium metastasis. The symptoms at presentation were panic and shortness of breath.

DIAGNOSES

The cytologic examination of pericardial fluid obtained by pericardiocentesis confirmed metastasis.

INTERVENTIONS

In addition to cisplatin instilled into the pericardial space, for systemic chemotherapy, we chose that gemcitabine and lobaplatin regimen be preferred.

OUTCOMES

The patient has been participating in telephone follow-up for 8 months and has generally remained in a good condition.

LESSONS

Endometrial carcinoma can have pericardial metastases. When this happens, we recommend ultrasound-guided pericardial puncture and the pericardial injection of cisplatin, in combination with systemic chemotherapy that consists of gemcitabine and lobaplatin.

Advanced Imaging Modalities to Monitor for Cardiotoxicity

Early detection and treatment of cardiotoxicity from cancer therapies is key to preventing a rise in adverse cardiovascular outcomes in cancer patients. Over-diagnosis of cardiotoxicity in this context is however equally hazardous, leading to patients receiving suboptimal cancer treatment, thereby impacting cancer outcomes. Accurate screening therefore depends on the widespread availability of sensitive and reproducible biomarkers of cardiotoxicity, which can clearly discriminate early disease. Blood biomarkers are limited in cardiovascular disease and clinicians generally still use generic screening with ejection fraction, based on historical local expertise and resources. Recently, however, there has been growing recognition that simple measurement of left ventricular ejection fraction using 2D echocardiography may not be optimal for screening: diagnostic accuracy, reproducibility and feasibility are limited. Modern cancer therapies affect many myocardial pathways: inflammatory, fibrotic, metabolic, vascular and myocyte function, meaning that multiple biomarkers may be needed to track myocardial cardiotoxicity. Advanced imaging modalities including cardiovascular magnetic resonance (CMR), computed tomography (CT) and positron emission tomography (PET) add improved sensitivity and insights into the underlying pathophysiology, as well as the ability to screen for other cardiotoxicities including coronary artery, valve and pericardial diseases resulting from cancer treatment. Delivering screening for cardiotoxicity using advanced imaging modalities will however require a significant change in current clinical pathways, with incorporation of machine learning algorithms into imaging analysis fundamental to improving efficiency and precision. In the future, we should aspire to personalized rather than generic screening, based on a patient’s individual risk factors and the pathophysiological mechanisms of the cancer treatment they are receiving. We should aspire that progress in cardiooncology is able to track progress in oncology, and to ensure that the current ‘one size fits all’ approach to screening be obsolete in the very near future.

Coronary Artery Vasospasm Induced by 5-fluorouracil: Proposed Mechanisms, Existing Management Options and Future Directions

Cardiovascular disease and cancer are leading contributors to the global disease burden. As a result of cancer therapy-related cardiotoxicities, cardiovascular disease results in significant morbidity and mortality in cancer survivors and patients with active cancer. There is an unmet need for management of cardio-oncology conditions, which is predicted to reach epidemic proportions, and better understanding of their pathophysiology and treatment is urgently required. The proposed mechanisms underlying cardiotoxicity induced by 5-fluorouracil (5-FU) are vascular endothelial damage followed by thrombus formation, ischaemia secondary to coronary artery vasospasm, direct toxicity on myocardium and thrombogenicity. In patients with angina and electrocardiographic evidence of myocardial ischaemia due to chemotherapy-related coronary artery vasospasm, termination of chemotherapy and administration of calcium channel blockers or nitrates can improve ischaemic symptoms. However, coronary artery vasospasm can reoccur with 5-FU re-administration with limited effectiveness of vasodilator prophylaxis observed. While pre-existing coronary artery disease may increase the ischaemic potential of 5-FU, cardiovascular risk factors do not appear to completely predict the development of cardiac complications. Pharmacogenomic studies and genetic profiling may help predict the occurrence and streamline the treatment of 5-FU-induced coronary artery vasospasm. Echocardiographic measures such as the Tei index may help detect subclinical 5-FU cardiotoxicity. Further research is required to explore the cardioprotective effect of agents such as coenzyme complex, GLP-1 analogues and degradation inhibitors on 5-FU-induced coronary artery vasospasm.

Pericardial thrombus and cardiac tamponade after pericardiocentesis with intact heart walls

A young patient affected by a lung neoplasm, presented at emergency department with cardiac tamponade, underwent pericardiocentesis with a prompt restoration of hemodynamic stability. An hour later, the patient presented again signs of tamponade, without evidence of fluids in the drainage that was left in pericardial space. The echocardiography revealed an intrapericardial thrombus compressing the right chambers. An emergency pericardiotomy was performed and a large thrombus was removed from the pericardial space; cardiac walls were intact. Echocardiography played a pivotal role for the identification of a pericardial thrombus as a complication of pericardiocentesis.
