Transient Constrictive Pericarditis: Current Diagnostic and Therapeutic Strategies

Transient pericardial constriction: A not so rare entity

Constrictive pericarditis is a rare, potentially treatable, cause of heart failure with preserved ejection fraction that is characterized by insidious onset, challenging diagnosis and dismal prognosis, even following complete surgical pericardiectomy, particularly in advanced disease stages. In recent years it has been proposed that transient pericardial constriction may occur, with an even rarer frequency, during early phases of acute pericarditis and may resolve following specific treatment without progressing to the chronic, irreversible form. We recently observed two cases of well-documented transient pericardial constriction. In the present work we describe these two cases and provide a review on this rare condition, that, if unrecognized and left untreated, may lead to irreversible constrictive pericarditis.

Transient constrictive pericarditis following coxsackievirus A4 infection as a rare cause of acute mediastinitis: A case report

Background

Transient constrictive pericarditis (TCP) is a distinct constrictive pericarditis (CP) subtype characterized by acute pericardial inflammation and transient constrictive physiology. If left untreated, it may progress to irreversible CP requiring pericardiectomy. However, making an early diagnosis of TCP remains difficult.

Case presentation

A 51-year-old man presented with fever, chest pain, and dyspnea following preceding flu symptoms. An initial investigation suggested right-sided heart failure. Laboratory results revealed elevated inflammatory markers and hepatic enzyme levels. Echocardiography revealed pericardial effusion with a normal ejection fraction and diastolic ventricular septal bounce suggestive of pericardial constriction. Computed tomography suggested acute descending mediastinitis with pericarditis and pleuritis; however, detailed examinations ruled out this possibility. The constellation of increased serological inflammation, pericardial thickness/effusion, and constrictive physiology suggested TCP, confirmed by cardiac magnetic resonance (CMR) and hemodynamic studies. CMR also revealed coexistent myocarditis. After a thorough assessment for the cause of TCP, a viral etiology was suspected. Paired serology for virus antibody titers revealed a significant increase only in coxsackievirus A4 (CVA4) titers. With prompt anti-inflammatory treatment, the patient's pericardial structure and function and concomitant inflammation of the surrounding tissues were nearly completely recovered, leading to a final diagnosis of TCP caused by CVA4. The subsequent clinical course was uneventful without recurrence at the 1-year follow-up.

Conclusions

Here we described the first case of TCP caused by CVA4 concurrent with mediastinitis, myocarditis, and pleuritis, all of which were successfully resolved with anti-inflammatory treatment. Acute mediastinitis secondary to TCP is rare. This case highlights the clinical importance of assessing pericardial diseases as a source of acute mediastinitis and considering CVA4 as an etiology of TCP. An evaluation including multimodal cardiac imaging and serology for virus antibody titers may be useful for an exploratory diagnosis of TCP in right-sided heart failure patients with pericardial effusion.

Multimodality Imaging of Constrictive Pericarditis: Pathophysiology and New Concepts

Purpose of Review

The unique pathophysiological changes of constrictive pericarditis (CP) can now be identified with better imaging modalities, thereby helping in its early diagnosis. Through this review, we outline the pathophysiology of CP and its translation into symptomology and various imaging findings which then are used for both diagnosis and guiding treatment options for CP.

Recent Findings

Multimodality imaging has provided us with the capability to recognize early stages of the disease and identify patients with a potential for reversibility and can be treated with medical management. Additionally, peri-procedural planning and prediction of post-operative complications has been made possible with the use of advanced imaging techniques.

Summary

Advanced imaging has the potential to play a greater role in identification of patients with reversible disease process and provide peri-procedural risk stratification, thereby improving outcomes for patients with CP.

Role of Cardiovascular Magnetic Resonance to Assess Cardiovascular Inflammation

Cardiovascular inflammatory diseases still represent a challenge for physicians. Inflammatory cardiomyopathy, pericarditis, and large vessels vasculitis can clinically mimic a wide spectrum of diseases. While the underlying etiologies are varied, the common physio-pathological process is characterized by vasodilation, exudation, leukocytes infiltration, cell damage, and fibrosis. Cardiovascular magnetic resonance (CMR) allows the visualization of some of these diagnostic targets. CMR provides not only morphological and functional assessment but also tissue catheterization revealing edema, hyperemia, tissue injury, and reparative fibrosis through T2 weighted images, early and late gadolinium enhancement, and parametric mapping techniques. Recent developments showed the role of CMR in the identification of ongoing inflammation also in other CV diseases like myocardial infarction, atherosclerosis, arrhythmogenic and hypertrophic cardiomyopathy. Future developments of CMR, aiming at the specific assessment of immune cell infiltration, will give deeper insight into cardiovascular inflammatory diseases.

A case report of tuberculous constrictive pericarditis as a sole manifestation of tuberculosis in a male adolescent

Constrictive pericarditis is a rare type of pericardial disease that can be caused by various factors. Tuberculosis (TB) is one of the most common causes of this abnormality in Indonesia. Interestingly, tuberculous constrictive pericarditis can occur in the absence of acute pericarditis, pulmonary, or extrapulmonary TB. This case described a male adolescent with refractory right-sided heart failure symptoms who developed a rapidly progressive tuberculous constrictive pericarditis. Various imaging modalities, such as echocardiography, chest computed tomography (CT) scan, cardiac magnetic resonance imaging, and incidental PET/CT scan, were used to diagnose the pericardial abnormality. Histopathological findings in pericardial tissues confirmed the diagnosis. Complete surgical pericardiectomy, in conjunction with anti-TB drugs, diuretics, and colchicine, resulted in a significant clinical improvement.

Cardiovascular complications of mantle field radiation: a case series

Background

Mantle field radiotherapy has been known to cause cardiovascular complications even years after therapy. Complications include pericardial disease, coronary artery disease, and conduction abnormalities.

Case summary

We present a case series of two patients who developed cardiovascular complications years after receiving mantle radiation. Patient 1 is a 52-year-old man who presented with symptoms of heart failure. He had a neurostimulator which precluded him from cardiac magnetic resonance imaging. Haemodynamic findings on right heart catheterization raised suspicion for constrictive pericarditis and pericardiectomy was performed. Histopathological analysis reported dense, sclerotic fibrous tissue consistent with radiation-related changes. Patient 2 is a 37-year-old man with a 2-month history of chest pain and exertional dyspnoea who was admitted for management of coronary artery disease. Coronary angiography demonstrated bilateral subclavian artery stenosis and an elevated left ventricular end-diastolic pressure (50 mmHg). He had bilateral percutaneous subclavian artery stenting. Both patients had complete resolution of symptoms on follow-up.

Discussion

Our case series emphasizes the need for an index of suspicion for radiation-related cardiovascular changes in patients who have a history of mantle radiation, especially in younger patients. This was especially pertinent in the case of our first patient who presented a diagnostic challenge due to certain patient factors. Our second patient is a case of subclavian artery stenosis which is less frequently reported as a complication of mantle radiation in the literature.

Multimodality imaging in pericardial diseases

With a rapidly growing spectrum, non-specific symptoms and overlapping etiologies, pericardial diseases can represent a real diagnostic challenge. Consequently, multimodality imaging has taken a front seat in the diagnosis and management of these conditions. Cardiac CT offers an excellent anatomical characterization of pericardial thickening, fat stranding and/or presence of calcifications. and is also the preferred modality to assess extra-cardiac structures. Active pericardial inflammation, edema and fibrosis comprise pericardial characterization using CMR and allows for a precise diagnosis, disease staging and patient specific tailoring of therapies. PET scan still occupies a very modest role in the evaluation of pericardial diseases, but might help discriminating malignant pericardial effusion and extra-pulmonary tuberculous. More than ever, clinicians need to master how these modalities complement each other while avoiding unnecessary cost and to translate this knowledge into a more customized patient's care approach. The aim of this review is to recognize the role of multimodality imaging in the investigation of various pericardial diseases, assess how these modalities can impact the clinical course and treatment of these affections and finally elucidate their role in the patient's prognostication.

Assessment of Pericardial Disease with Cardiovascular MRI

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

A Complicated Case of Transient Constrictive Pericarditis Secondary to Rivaroxaban-Associated Hemopericardium

A 72-year-old man on rivaroxaban developed effusive constrictive pericarditis secondary to hemopericardium. His condition improved with anti-inflammatory therapy supporting a diagnosis of transient constrictive pericarditis. On follow-up, residual constriction developed requiring surgical pericardiectomy. Although many cases with transient constrictive pericarditis resolve with medical management, some may progress and require pericardiectomy. (Level of Difficulty: Advanced.)

Pericarditis and Post-cardiac Injury Syndrome as a Sequelae of Acute Myocardial Infarction

PURPOSE OF REVIEW

Pericarditis secondary to acute myocardial infarction (AMI) is known to develop either immediately or after a latent period of few months. Due to varied presentation and timing, its diagnosis and treatment can be challenging. This article reviews underlying mechanisms and the role of cardiac imaging in investigating and managing this condition.

RECENT FINDINGS

Timely diagnosis of pericarditis after AMI is important to prevent potential progression to complicated pericarditis. Clinical suspicion warrants initial investigation with serum inflammatory levels, electrocardiogram, and echocardiography. When findings are inconclusive, cardiac magnetic resonance imaging and computerized tomography can provide additional diagnostic information. Pericarditis after AMI is a treatable condition. Clinicians should maintain a high suspicion in this era of revascularization and develop a strategic plan for timely diagnosis and management.

Subacute pericardial abscess after aortic valve replacement: a case report

Background

Purulent pericarditis is an infectious disease, frequently caused by gram-positive bacteria, that is rarely observed in healthy individuals, and is often associated with predisposing conditions.

Case presentation

Here, we present the case of an Escherichia coli post-surgical localized purulent pericarditis complicated by transient constrictive pericarditis and its diagnostic and therapeutic management.

Conclusions

Our case report focuses on the importance of imaging-guided treatment of purulent pericardial diseases, in particular on the emerging role of 18 F-labelled 2-fluoro-2-deoxy-D-glucose Positron Emission Tomography/Computed Tomography in pericardial diseases and on the management of transient constrictive pericarditis, often seen after thoracic surgery.

Acute Transient Effusive-Constrictive Pericarditis

A 52-year-old female developed acute idiopathic pericarditis, which was complicated with tamponade. Constrictive physiology persisted after pericardiocentesis, and effusive-constrictive pericarditis (ECP) was diagnosed. Constrictive physiology improved in 10 days with anti-inflammatory therapy. This case was remarkable because it showed that ECP may present in an acute and reversible form. (Level of Difficulty: Beginner.)

The effects of adding angiotensin receptor neprilysin inhibitors to usual care in patients with heart failure: a protocol for a systematic review of randomised clinical trials with meta-analysis and trial sequential analysis

BACKGROUND

Heart failure is a highly prevalent disease with a global prevalence of 37 million, and the prevalence is increasing. Patients with heart failure are at an increased risk of death and morbidity. Traditionally, patients with heart failure have been treated with a beta-blocker in addition to an inhibitor of the renin-angiotensin-aldosterone system. However, new drugs are currently being added to the recommended guideline therapy. The latest drug to be added combines inhibition of the renin-angiotensin-aldosterone system pathway with inhibiting the neprilysin enzyme and is therefore classified as an ARNI. Our objective is to identify the beneficial and harmful effects of ARNIs in the treatment of patient with heart failure.

METHODS

This protocol for a systematic review was undertaken using the recommendations of the Cochrane, the Preferred Report Items of Systematic reviews with Meta-Analysis Protocols, and the eight-step assessment procedure suggested by Jakobsen and colleagues. We plan to include all relevant randomised clinical trials assessing the use of ARNIs in the treatment of patients with heart failure. We will search the Cochrane Central Register of Controlled Trials (CENTRAL), Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE), Latin American and Caribbean Health Sciences Literature (LILACS), Science Citation Index Expanded on Web of Science, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Chinese Science Journal Database (VIP), and BIOSIS to identify relevant trials. We will also search for grey literature and unpublished trials. Extracted data will be analysed using Review Manager 5, STATA 5, and Trial Sequential Analysis. Our primary outcomes will be all-cause mortality and serious adverse events. We will create a 'Summary of Findings' table in which we will present our primary and secondary outcomes, and we will assess the quality of evidence using the GRADE assessment.

DISCUSSION

The present systematic review will have the potential to aid clinicians in decision-making and thereby, benefit patients with heart failure.

A rare cause of ascites in a renal transplant recipient

Thirty-five-year-old man, underwent renal transplantation 4 years back and was doing well. He now presented with complaints of ascites with engorged neck veins and dyspnoea on exertion for last 6 months. Examination showed elevated jugular venous pressure with two prominent descents, high pitched diastolic heart sound (pericardial knock). Echocardiography showed characteristic features of thickened pericardium, septal bounce, expiratory flow reversal in hepatic veins and phasic variation of mitral inflow, suggestive of constrictive pericarditis. The patient was started on empirical antitubercular therapy and diuretics. The patient symptomatically improved, but in view of persisting constrictive physiology he was planned for pericardiectomy.

Imaging of the Pericardium: A Multimodality Cardiovascular Imaging Update

Pericardial diseases represent diverse conditions, ranging from painful inflammatory states, such as acute pericarditis, to life-threatening tamponade and chronic heart failure due to constrictive pericarditis. Multimodality cardiovascular imaging plays important roles in diagnosis and management of pericardial conditions. This review provides a clinical update on multimodality cardiovascular imaging of the pericardium, incorporating echocardiography, multidetector computed tomography, and cardiac magnetic resonance imaging, focusing on guiding clinicians about when each cardiac imaging modality should be used in each relevant pericardial condition.

Cardiac tamponade and adrenal insufficiency due to pembrolizumab: a case report

Introduction

Patients who receive or have received anti-programmed cell-death-1 (PD-1) monoclonal antibodies can develop immune-related adverse events due to activation of the immune system.

Case presentation

We report a case of a patient who received pembrolizumab and presented with cardiac tamponade. Despite pericardial drainage, she persisted with refractory arterial hypotension due to secondary adrenal insufficiency. After initiating corticosteroid therapy, the patient recovered successfully.

Discussion

The association of pericarditis, hypophysitis and thyroid dysfunction support the diagnosis of a life-threatening immune-related adverse event due to pembrolizumab. In case of immune-related adverse events secondary to anti-PD-1 monoclonal antibodies, corticosteroid therapy should be promptly initiated in order to avoid major complications.

Utility of multimodality cardiac imaging in disorders of the pericardium

Disorders of the pericardium represent a diverse range of conditions that traditionally may not have received the same level of attention by cardiologists and physicians, owing partly to a lack of research into advanced diagnostic modalities, and limited, evidence-based treatment options. In recent years, there has been a timely resurgence of interest in pericardial diseases, in particular pericarditis. This is attributable to advances in multi-modality cardiovascular imaging, in particular cardiac magnetic resonance (CMR), which may help guide treatment decisions for patients with pericardial syndromes. Additionally, increased research and understanding of the pathophysiological basis of pericarditis have shed light on the role of inflammation in pericarditis. This knowledge may help identify potential specific treatment targets. This article aims to provide a practical review of the role of multimodality cardiovascular imaging (echocardiography, multidetector cardiac computed tomography (MDCT), CMR) in pericardial conditions, focusing on the strengths and potential limitations of each imaging modality.

New Insights into Pericarditis: Mechanisms of Injury and Therapeutic Targets

PURPOSE OF REVIEW

This review article aims to provide a contemporary insight into the pathophysiological mechanisms of and therapeutic targets for pericarditis, drawing distinction between autoinflammatory and autoimmune pericarditis.

RECENT FINDINGS

Recent research has focused on the distinction between autoinflammatory and autoimmune pericarditis. In autoinflammatory pericarditis, viruses can activate the sensor molecule of the inflammasome, which results in downstream release of cytokines, such as interleukin-1, that recruit neutrophils and macrophages to the site of injury. Conversely, in autoimmune pericarditis, a type I interferon signature predominates, and pericardial manifestations coincide with the severity of the underlying systemic autoimmune disease. In addition, autoimmune pericarditis can also develop after cardiac injury syndromes. With either type of pericarditis, imaging can help stage the inflammatory state. Prominent pericardial delayed hyperenhancement on magnetic resonance imaging suggests ongoing inflammation whereas calcium on computed tomography suggests a completed inflammatory cascade. In patients with ongoing pericarditis, treatments that converge on the inflammasome, such as colchicine and anakinra, have proved effective in recurrent autoinflammatory pericarditis, though further clinical trials with anakinra are warranted. An improved understanding of the pathophysiological mechanisms of pericarditis helps unravel effective therapeutic targets for this condition.

Multimodality Imaging of Pericardial Diseases

OPINION STATEMENT

Pericardial diseases have changed their epidemiology in the past few years. With the aging population and decreasing incidence of communicable diseases, the causes of pericardial diseases have significantly changed from infectious and malignant to postradiation and cardiac surgery causes. Despite that, pericardial diseases remain difficult to diagnose. The accurate and timely diagnosis of these diseases is essential to avoid the late sequela of pericardial constriction and pericardial cirrhosis. Echocardiography remains the first test of choice for the assessment of patients with suspected pericardial diseases. Most patients with acute pericarditis have a self-limiting course and do not need further imaging. However, in the era of multimodality imaging, other modalities, namely, computed tomography (CT) and magnetic resonance imaging (CMR), are often utilized in complex cases. These two modalities provide a wide-open view of the pericardium and adjacent structures. They have high resolution to assess pericardial calcification, a hallmark of many diseases especially tuberculous constrictive pericarditis. CMR is also unique in its ability to assess pericardial late gadolinium enhancement (LGE) and edema. These have been recently suggested to be very important in the progression from acute pericarditis to constrictive pericarditis. In addition, they provide prognostic value to assess which patients are at high risk of developing heart failure and resource utilization. Thus, in the current era, patients with suspected complex pericardial diseases will need a multimodality approach rather than a single modality approach.

Invasive Hemodynamics of Pericardial Disease

Pericardial diseases can be classified broadly as 3 entities: acute pericarditis, cardiac tamponade, and constrictive pericarditis. These disorders can be diagnosed and managed with noninvasive studies following a comprehensive history and physical examination, without the need for cardiac catheterization in most patients. Despite the advances in noninvasive cardiac imaging, there are limitations to their diagnostic accuracy. The invasive hemodynamic study offers the advantage of simultaneous, direct pressure measurement across multiple chambers, with direct examination of blood flow. Herein, the authors review the techniques for obtaining and interpreting invasive hemodynamic data in patients with suspected pericardial disease.

Incremental value of PET and MRI in the evaluation of cardiovascular abnormalities

Abstract

The cardiovascular system is affected by a wide range of pathological processes, including neoplastic, inflammatory, ischemic, and congenital aetiology. Magnetic resonance imaging (MRI) and positron emission tomography (PET) are state-of-the-art imaging modalities used in the evaluation of these cardiovascular disorders. MRI has good spatial and temporal resolutions, tissue characterization and multi-planar imaging/reconstruction capabilities, which makes it useful in the evaluation of cardiac morphology, ventricular and valvar function, disease characterization, and evaluation of myocardial viability. FDG-PET provides valuable information on the metabolic activity of the cardiovascular diseases, including ischemia, inflammation, and neoplasm. MRI and FDG-PET can provide complementary information on the evaluation of several cardiovascular disorders. For example, in cardiac masses, FDG-PET provides the metabolic information for indeterminate cardiac masses. MRI can be used for localizing and characterizing abnormal hypermetabolic foci identified incidentally on PET scan and also for local staging. A recent advance in imaging technology has been the development of integrated PET/MRI systems that utilize the advantages of PET and MRI in a single examination. The goal of this manuscript is to provide a comprehensive review on the incremental value of PET and MRI in the evaluation of cardiovascular diseases.

Main Messages

• MRI has good spatial and temporal resolutions, tissue characterization, and multi-planar reconstruction

• FDG-PET provides valuable information on the metabolic activity of cardiovascular disorders
