RESUMEN
A 55-year-old male with acute pericarditis presented with low-pressure cardiac tamponade (LPCT) unresponsive to volume infusion. Subsequent pericardiocentesis resulted in hemodynamic improvement and unmasking of pericardial constriction. This case provides illustrative hemodynamic tracings of LPCT. Additionally, the presence of concurrent pericardial constriction that may indicate a plausible underlying mechanism for the blunted responsiveness to fluid expansion in LPCT. The underlying physiologic processes and the associated hemodynamic tracings are discussed.

OBJECTIVE: Our study aimed to explore with cardiovascular magnetic resonance (CMR) the impact of left atrial (LA) and left ventricular (LV) myocardial strain in patients with acute pericarditis and to investigate their possible prognostic significance in adverse outcomes. METHOD: This retrospective study performed CMR scans in 36 consecutive patients with acute pericarditis (24 males, age 52 [23-52]). The primary endpoint was the combination of recurrent pericarditis, constrictive pericarditis, and surgery for pericardial diseases defined as pericardial events. Atrial and ventricular strain function were performed on conventional cine SSFP sequences. RESULTS: After a median follow-up time of 16 months (interquartile range [13-24]), 12 patients with acute pericarditis reached the primary endpoint. In multivariable Cox regression analysis, LA reservoir and LA conduit strain parameters were all independent determinants of adverse pericardial diseases. Conversely, LV myocardial strain parameters did not remain an independent predictor of outcome. With receiving operating characteristics curve analysis, LA conduit and reservoir strain showed excellent predictive performance (area under the curve of 0.914 and 0.895, respectively) for outcome prediction at 12 months. CONCLUSION: LA reservoir and conduit mechanisms on CMR are independently associated with a higher risk of adverse pericardial events. Including atrial strain parameters in the management of acute pericarditis may improve risk stratification. CLINICAL RELEVANCE STATEMENT: Atrial strain could be a suitable non-invasive and non-contrast cardiovascular magnetic resonance parameter for predicting adverse pericardial complications in patients with acute pericarditis. KEY POINTS: ⢠Myocardial strain is a well-validated CMR parameter for risk stratification in cardiovascular diseases. ⢠LA reservoir and conduit functions are significantly associated with adverse pericardial events. ⢠Atrial strain may serve as an additional non-contrast CMR parameter for stratifying patients with acute pericarditis.

BACKGROUND: ECG is the initial diagnostic tool that in combination with typical symptoms often raises the suspicion of pericarditis. Echocardiography remains the first-line imaging modality for assessment of pericardial diseases, particularly effusion/tamponade, constrictive physiology, and assessment of regional wall motion abnormalities as differential diagnoses. However, cardiac CT and cardiac magnetic resonance may be necessary in complicated cases and to identify pericardial inflammation in specific settings (atypical presentation, new onset constriction), as well as myocardial involvement and monitoring the disease activity. SUMMARY: In acute pericarditis, the most commonly used ECG criteria recommended by international guidelines are the widespread ST-segment elevation or PR depression. However, the classic ECG pattern of widespread ST-segment elevation or PR depression can be seen in less than 60% of patients. In addition, ECG changes are often temporally dynamic, evolve rapidly during the course of disease, and may be influenced by a number of factors such as disease severity, time (stage) of presentation, degree of myocardial involvement, and the treatment initiated. Overall, temporal dynamic changes on ECG during acute pericarditis or myopericarditis have received limited attention. Hence, the aim of this brief clinical review was to increase awareness about the various ECG changes observed during the course of acute pericarditis. KEY MESSAGES: ECG may be normal at presentation or for days after the index episode of chest pain, but serial ECGs can reveal specific patterns of temporally dynamic ST elevation in patients with pericarditis or myopericarditis, particularly during new episodes of chest pain.

ABSTRACT: Pericarditis is a challenging diagnosis with nonspecific manifestations, significant clinical implications, and possible mortality. The advancement of imaging, such as echocardiography, computed tomography (CT), and magnetic resonance imaging (MRI), has improved the sensitivity of diagnosis, although limitations remain. In this study, we investigated the prevalence of pericarditis identified at autopsy and correlated these findings with antemortem imaging studies and clinical information. Thirty-four decedents were identified in our archival autopsy records (prevalence, 1.23%) from 2010 to 2021 with a postmortem diagnosis of pericarditis. Thirty-five antemortem imaging studies were performed on 32 decedents, of which CT was the most common (18/35, 51.4%). The sensitivity of antemortem imaging was poor, with CT showing the highest sensitivity at 16.7% (3/18), while echocardiography studies, transthoracic (TTE) and transesophageal (TEE), each had a sensitivity of 0.0%. Pericarditis was determined as the immediate cause of death by autopsy in 13 decedents, of which 3 were diagnosed antemortem. It was considered contributory to the death in 6 decedents, none of which were diagnosed antemortem. In summary, antemortem imaging has limited utility in the diagnosis of pericarditis. It is imperative to examine the pericardium during autopsy to identify a possible cause of death or contributing factor.

OBJECTIVES: To assess clinical and cardiac magnetic resonance (CMR) imaging features of patients with peri-myocarditis following Coronavirus Disease 2019 (COVID-19) vaccination. METHODS: We retrospectively collected a case series of 27 patients who underwent CMR in the clinical suspect of heart inflammation following COVID-19 vaccination, from 16 large tertiary centers. Our patient's cohort was relatively young (36.6 ± 16.8 years), predominately included males (n = 25/27) with few comorbidities and covered a catchment area of approximately 8 million vaccinated patients. RESULTS: CMR revealed typical mid-subepicardial non-ischemic late gadolinium enhancement (LGE) in 23 cases and matched positively with CMR T2 criteria of myocarditis. In 7 cases, typical hallmarks of acute pericarditis were present. Short-term follow-up (median = 20 days) from presentation was uneventful for 25/27 patients and unavailable in two cases. CONCLUSIONS: While establishing a causal relationship between peri-myocardial inflammation and vaccine administration can be challenging, our clinical experience suggests that CMR should be performed for diagnosis confirmation and to drive clinical decision-making and follow-up. KEY POINTS: ⢠Acute onset of dyspnea, palpitations, or acute and persisting chest pain after COVID-19 vaccination should raise the suspicion of possible myocarditis or pericarditis, and patients should seek immediate medical attention and treatment to help recovery and avoid complications. ⢠In case of elevated troponin levels and/or relevant ECG changes, cardiac magnetic resonance should be considered as the best non-invasive diagnostic option to confirm the diagnosis of myocarditis or pericarditis and to drive clinical decision-making and follow-up.

INTRODUCTION: In the last few months, some pediatric cases with neurological and neuroradiological pictures related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections have been reported, often associated with multisystem inflammatory syndrome (MIS-C). The most frequently encountered pediatric neurological complications seem to be postinfectious immune-mediated acute disseminated encephalomyelitis (ADEM)-like changes of the brain, myelitis, neural enhancement, and splenial lesions. Concomitant neurological and cardiac involvement has been reported only in MIS-C, although specific clinical details are often not fully available. METHODS: In this case report, a very young child infected with SARs-CoV-2 and diagnosed as longitudinal extensive transverse myelitis with concomitant myo-pericarditis is presented. RESULTS: A previously healthy 7-month-old girl presented with abrupt onset of generalized weakness with inability to sit up. She had had mild respiratory symptoms 1 week earlier. Spinal magnetic resonance imaging (MRI) showed a T2-hyperintense intramedullary lesion extending from C4 to T2, compatible with acute longitudinally extensive transverse myelitis (LETM). Cerebrospinal fluid analysis was negative.Echocardiography and blood tests were suggestive for myo-pericarditis. Real time polymerase chain reaction for SARS-CoV-2 on nasopharyngeal swab sample tested positive. She was promptly treated with high dose of steroids and immunoglobulin with satisfactory clinical response. CONCLUSION: To the evolving literature of neurological complications of SARs-CoV-2 infection, we add the youngest patient described to date with isolated LETM and concomitant cardiac involvement. Our case suggests that clinicians should be aware of this association, although difficult to recognize in infants. Practitioners are encouraged to consider aggressive first-line immunotherapies with the final aim to prevent permanent disability.

The objective of this case report is to highlight a rare case of infectious thoracic aortic aneurysm and purulent pericarditis simultaneously in a 56-year-old woman. The patient complained of left anterior chest pain and contrast computed tomography (CT) revealed infectious thoracic aortic aneurysm and purulent pericarditis accompanied by massive pericardial effusion. She underwent a pericardial drainage immediately, and antibiotic treatment was initiated. Methicillin-sensitive Staphylococcus aureus was detected in blood and pericardial fluid cultures. On day eight of hospitalization, contrast CT scan showed enlargement of the aortic aneurysm. Therefore, total arch replacement was performed on day 10 using rifampicin-soaked graft. After surgery, antibiotic treatment was continued, till inflammatory markers became negative. She was discharged on day 66 without developing anastomotic pseudoaneurysms nor constrictive pericarditis.

BACKGROUND: Recent evidence suggests that cardiac involvement in patients with granulomatosis with polyangiitis (GPA) occurs more frequently than previously reported. Multimodality cardiac imaging is gaining attention in the diagnosis, prognostication, and follow-up of such patients; however, the data remain scarce. RESULTS: 2D-TTE was useful for initial screening; while both cardiac magnetic resonance imaging and 18F-fluoro-2-deoxyglucose positron emission tomography/computed tomography (18FDG-PET/CT) metabolic imaging with rubidium-82 PET perfusion imaging were useful for characterization of myocardial disease. 18FDG-PET/CT was very useful for the follow-up of cardiac disease activity following treatment. CONCLUSION: 18FDG-PET/CT is sensitive for the detection of cardiac involvement by GPA and is useful for the tissue characterization and follow-up of disease activity following treatment.

BACKGROUND: Post cardiac injury syndrome (PCIS) is induced by myocardial infarction or cardiac surgery, as well as minor insults to the heart such as percutaneous coronary intervention (PCI), or insertion of a pacing lead. PCIS is characterized by pericarditis after injury to the heart. The relatively low incidence makes differential diagnosis of PCIS after PCI or implantation of a pacemaker a challenge. This report describes two typical cases of PCIS. CASE PRESENTATION: The first patient presented with signs of progressive cardiac tamponade that occurred two weeks after implantation of a permanent pacemaker. Echocardiography confirmed the presence of a moderate amount of newly-formed pericardial effusion. The second patient underwent PCI for the right coronary artery. However, despite an uneventful procedure, the patient experienced dyspnea, tightness of chest and cold sweats, and bradycardia two hours after the procedure. Echocardiography findings, which showed a moderate amount of newly-formed pericardial effusion, suggested acute cardiac tamponade, and compromised hemodynamics. Both patients recovered with medication. CONCLUSION: These cases illustrated that PCIS can occur after minor myocardial injury, and that the possibility of PCIS should be considered if there is a history of possible cardiac insult.

Immune checkpoint inhibitors (ICIs), a form of immunotherapy, are increasingly used for a variety of malignancies and have been linked to numerous treatment-related side effects known as immune-related adverse events (irAEs). IrAEs can affect multiple organ systems and are important to recognise in order to avoid misinterpretation as progressive tumour and to ensure appropriate management. In this pictorial review, we will briefly discuss radiological response criteria of immunotherapy and describe the imaging appearances of the wide spectrum of these ICI-associated toxicities.

ABSTRACT: Mycobacterium infection remains a leading cause of morbidity and mortality worldwide. Although rare, thoracic cardiovascular complications are associated with devastating consequences if not promptly diagnosed using computed tomography. Intrapulmonary complications include tuberculous aortitis, Rasmussen aneurysms, involvement of bronchial and nonbronchial systemic arteries, and thromboembolic events. Extrapulmonary complications include pericarditis, myocarditis, endocarditis, involvement of coronary arteries, annular-subvalvular left ventricle aneurysms and mediastinal fibrosis. This article will review these complications and their computed tomography features.

Gastropericardial fistula is a rare but lethal condition. Several etiologies have been reported, including previous gastric or esophageal surgery, malignancy, trauma, infection, and ulcer perforation. Typical symptoms included chest pain, epigastric pain, fever and dyspnea. Gastropericardial fistula can lead to serious complications, including cardiac tamponade, sepsis, hemodynamic compromise and death. Therefore, early diagnosis and timely management are important for physicians to prevent from catastrophic complications. Here, we present a case of a man who presented with acute purulent pericarditis secondary to a gastropericardial fistula to highlight the pathogenesis and suggest therapeutic strategies.

Pericarditis is a rare but debilitating complication of cytarabine therapy. While echocardiography can aid with the diagnosis, cardiac MRI has superior accuracy in establishing the diagnosis. In this case, we describe a 65-year-old patient receiving cytarabine as part of induction chemotherapy for acute myeloid leukemia who developed acute pericarditis. Her cardiac MRI revealed pericardial edema on T2-weighted STIR imaging and pericardial late gadolinium enhancement which confirmed the diagnosis.

PURPOSE OF REVIEW: Pericardial diseases include a wide range of pathologies and their diagnosis can often be challenging. The goal of this review is to describe the established and emerging CMR imaging techniques used in the assessment of common pericardial diseases and explain the role of pericardial characterization in their diagnosis and management. RECENT FINDINGS: CMR is indicated in cases of diagnostic uncertainty and for a comprehensive evaluation of the pericardium and its impact on the heart. This includes assessment of pericardial anatomy and associated cardiac hemodynamics, quantification and characterization of an effusion, disease staging, tissue characterization, guiding management, and even prognostication in some diseases of the pericardium. An emerging technique, pericardial characterization, utilizes various sequences to diagnose and stage pericardial inflammation, act as a biomarker in recurrent pericarditis, and guide management in inflammatory pericardial conditions. Beyond imaging, it has ushered in an era of tailored therapy for patients with pericardial diseases. Future directions should aim at exploring the role of tissue characterization in various pericardial diseases.

PURPOSE OF REVIEW: Coronavirus disease 2019 (COVID19) involves the heart, including pericardium. This article reviews the possible pathophysiological mechanisms in pericardial involvement in COVID19 and pericardial manifestations of COVID19. It also summarizes the patients with pericarditis secondary to COVID19 and outlines the contemporary treatment strategies in this patient population. RECENT FINDINGS: A high degree of suspicion is required to identify the pericardial involvement in COVID19 patients. It is proposed that an underlying hyperinflammatory reaction in COVID19 leads to pericardial inflammation. Acute pericarditis with or without myocardial involvement is diagnosed on clinical presentation, serum inflammatory markers, electrocardiogram, and echocardiogram. Multimodality imaging may also have an additional diagnostic value. Patients are usually managed medically, but some patients develop a life-threatening pericardial tamponade necessitating pericardial drainage. Pericardial involvement is an important clinical manifestation of COVID19 requiring a proper workup. Timely diagnosis and a specific management plan based on the presentation and concomitant organ involvement usually lead to a complete recovery.

The patient was a 41-year-old man. He was diagnosed with pleurisy and came to our hospital. The pleural effusion and pleurisy remained even after administration of sufficient doses of antibiotics. A thorough examination revealed an anterior mediastinal tumor. Six months later, pericarditis also developed. Autoimmune diseases, infections, and malignant diseases were suspected, but a definitive diagnosis could not be made. In order to confirm the diagnosis, anterior mediastinal tumor resection and pleural biopsy were performed. The anterior mediastinal tumor was diagnosed as cholesterin granuloma pathollogically. Cholesterin granuloma is a granuloma formed by deposition of cholesterin crystals and cholesterin granuloma occurring in the mediastinum is extremely rare.

BACKGROUND: Pericardial constriction is one of the complications of purulent pericarditis (PP). Most difficult to treat, which may develop both in early and in the late period of the disease, resulting in a very poor prognosis. CASE PRESENTATION: We present case series of 4 patients with purulent pericarditis, in whom direct intrapericardial administration of recombinant tissue plasminogen activator (r-tPA) was used. Management of PP requires a combined surgical and medical approach. The most important is complete drainage of the effusion by subxiphoid pericardiotomy connected with complementary use of broad-spectrum antibiotics. Despite the use of broad- spectrum antibiotics, in some patients a large volume of daily drainage is still present. Constrictive pericarditis as a complication of PP is observed in majority of patients. Intrapericardial administration of fibrinolytic agents, although not strongly recommended, can improve efficacy of antibiotic treatment especially in patients with loculation fluid and can prevent the development of constrictive pericarditis. r-tPA was applied at a dose of 20 mg dissolved in 100 ml of normal saline in a 100 ml syringe, administered by a large pericardial drain (Pezzer drain) installed into the pericardial cavity during pericardioscopy. The tube was closed and re-opened after 24 h. No serious complications, such as bleeding, allergy or hypotension, were noted. CONCLUSION: We present case series of 4 patients with purulent pericarditis, in whom direct intrapericardial administration of recombinant tissue plasminogen activator (r-tPA), prevented the development of constrictive pericarditis, and increased efficacy of antibiotic treatment without any significant complications.
