Background Plasma levels and N-terminal pro B-type natriuretic peptide (NT- proBNP), a cardiac neurohormone released in response to increased ventricular stress, represent an important predictor of clinical outcomes and left ventricular (LV) dysfunction; Although, its diagnostic and prognostic role in patients with acute myocarditis is not completely established; Our aim was to evaluate the relationship of BNP levels and LV ejection fraction (LVEF) in patients with myocarditis; Methods Data from patients (pts) discharged with the diagnosis of myocarditis, from 2008 and 2018 were retrospectively analysed. Results 62 pts were included. Mean age was 39.7 17 years and 89% (58 patients) were men. Plasma levels of NT-proBNP measured at admission ranged from 24 to 3110 pg/mL (median 514, IQR 947), and exceeded upper normal levels in 51 pts (82%). This values positively correlated with C- reactive protein (CRP) (p= 0.005, r = 0.36), leucocytes (p = 0.03, r= 0.37) and neutrophil-to-lymphocyte ratio (p= 0.05, r= 0.35), but not with left ventricular ejection fraction (LVEF) (p= 0.829). Higher levels of BNP were associated with higher troponin peak levels but not with increased mortality (p = 0.811), need of inotropic support (p= 0.059) or arrhythmic events (p= 0.130). Inflammatory parameters were significantly increased when BNP> 514 pg/mL vs BNP <514 pg/mL (CRP 7.2 vs 4 mg/dL, p= 0.008). This relationship was maintained at BNP > 900. LVEF was comparable in both groups (p = 0.938); In this population, the magnitude of recovery of the NT- proBNP values (variation between NT-proBNP at admission and discharge) strongly correlated with the magnitude of the inflammatory markers at admission (all p < 0,005) Conclusion In patients with acute myocarditis, there is a significant relationship between NT-proBNP levels and inflammation (as measured by leucocytes, NLR or CRP), but not with LVEF; Despite the limitation of a small sample size, we could hypothesize that NTproBNP in this subset of patients appears to be regulated not only by hemodynamic changes but also by the underlying systemic inflammatory process and, therefore, it interpretation should take that into account;

Staphylococcus aureus myocarditis is a rare diagnosis with a high mortality rate, usually seen in people who are immunocompromised. Here, we report a case of a 44-year-old man on methotrexate for rheumatoid arthritis who presented in septic shock and was diagnosed with staphylococcus aureus myocarditis. The myocarditis was associated with a left ventricular apical thrombus, with normal systolic function. The myocarditis and associated thrombus were characterised on transthoracic echocardiogram and subsequently on cardiac magnetic resonance imaging. Cardiac magnetic resonance (CMR) imaging showed oedema in the endomyocardium, consistent with acute myocarditis, associated with an apical mural thrombus. Repeat CMR 3 weeks following discharge from hospital showed marked improvement in endomyocardial oedema and complete resolution of the apical mural thrombus. He was treated with a 12-week course of antibiotics and anticoagulated with apixaban. The patient was successfully managed with intravenous antibiotics and anticoagulation with complete recovery.

Prognostic Stratification

Abstract Background Cardiac magnetic resonance (CMR) plays a central role in the diagnosis, follow-up and prognostic stratification of acute myocarditis. Several CMR features, including the extent of late gadolinium enhancement (LGE) at baseline, have been proposed as factors associated with a worse outcome. Recent studies evaluated temporal evolution of LGE and edema repeating CMR either at 6 months or at 12 months, demonstrating that persistence or worsening of LGE represents a negative prognostic marker. However, the time-course of edema resolution and LGE stabilization is currently unknown and therefore the optimal timing to repeat CMR for acute myocarditis prognostic stratification remains unclear. Purpose We aimed to assess the time course of edema and LGE evolution in order to identify the optimal timing to repeat CMR in patients with acute myocarditis. Methods We enrolled 36 patients with a diagnosis of acute myocarditis according to ESC position statement definition. All patients underwent CMR at clinical presentation (CMR-1), after 3–4 months (CMR-2) and after 12-months (CMR-3) follow-up. CMR evaluation included assessment of edema and LGE, and evaluation of structural and functional parameters including left (LVEF) and right ventricular ejection fraction (RVEF), left (LVGLS) and right ventricular global longitudinal strain (RVGLS) and indexed left ventricular mass (iLVM). After CMR-3 all patients were followed-up by yearly clinical evaluation, electrocardiogram (ECG) and 2D-echocardiography. Results The mean age was 28,8±10,3 years with 35 (97%) being male. All patients showed edema and LGE at CMR-1 with a LVEF of 58,5±12,2. At CMR-2 a significant reduction of edema (T2 positive segments 0,4±0,9 vs. 4,1±3,2 p<0.0001) and LGE extent (LGE ≥5SD 5,1±5,3 vs. 9,6±8,4 p<0.0001) was observed, with only 3 patients showing edema persistence. A significant improvement of LVEF (62,7±5,6 vs. 58,5±12,2 p<0.05), RVGLS (−24,4±5,4 vs. −21,6±7,4 p<0.05), associated with a significant reduction of iLVM (71,2±13,7 vs 78,1±15,2 g/mq) was also observed. At CMR-3 no further significant reduction of LGE extent was observed with no further improvement of LVEF, RVGLS and iLVM. In the 3 patients with persisting edema at CMR-2, a complete resolution was observed at CMR-3. After a mean follow-up of 60±23 months, no major cardiovascular events nor myocarditis recurrences were observed, with no patients showing left ventricular dysfunction nor progression to dilated cardiomyopathy at 2D-echocardiography. Conclusions In most patients with acute myocarditis a complete resolution of the inflammatory process with LGE stabilization and normalization of left ventricular function and mass can be observed after 3–4 months. Further CMR assessment should limited to patients with persisting oedema at 3–4 months CMR. Our findings suggest to redefine the follow-up schedule and imaging-based prognostic stratification strategies in patients with acute myocarditis.

Deep neck space infection and viral myocarditis related to coronavirus disease 2019 (COVID-19) have both been described in the medical literature. However, there are only three reported cases of retropharyngeal infection as a presenting pathology in the setting of COVID-19. A 26-year-old woman presented to the emergency room with fever and neck swelling and pain 1 month after COVID-19 infection. A computed tomography scan of the neck demonstrated tonsillitis with retropharyngeal infection. She was also found to have heart failure with an ejection fraction (EF) of <20% due to acute myocarditis. Her infection resolved and the EF improved to 40% prior to discharge. Our case is the first to describe retropharyngeal infection as a late complication in an adult with a history of COVID-19 several weeks previously. It also presented a clinical challenge in terms of tailoring goal-directed medical therapy to manage severe left ventricular dysfunction caused by myocarditis.

The Impact

Cardiovascular magnetic resonance (CMR) is used to investigate suspected acute myocarditis, however most supporting data is retrospective and few studies have included parametric mapping. We aimed to investigate the utility of contemporary multiparametric CMR in a large prospective cohort of patients with suspected acute myocarditis, the impact of real-world variations in practice, the relationship between clinical characteristics and CMR findings and factors predicting outcome. 540 consecutive patients we recruited. The 113 patients diagnosed with myocarditis on CMR performed within 40 days of presentation were followed-up for 674 (504–915) days. 39 patients underwent follow-up CMR at 189 (166–209) days. CMR provided a positive diagnosis in 72% of patients, including myocarditis (40%) and myocardial infarction (11%). In multivariable analysis, male sex and shorter presentation-to-scan interval were associated with a diagnosis of myocarditis. Presentation with heart failure (HF) was associated with lower left ventricular ejection fraction (LVEF), higher LGE burden and higher extracellular volume fraction. Lower baseline LVEF predicted follow-up LV dysfunction. Multiparametric CMR has a high diagnostic yield in suspected acute myocarditis. CMR should be performed early and include parametric mapping. Patients presenting with HF and reduced LVEF require closer follow-up while those with normal CMR may not require it.

Objective: To find out characteristics and clinical features of children presenting with acute myocarditis at a tertiary care hospital. Study Design: Observational Study. Setting: Department of Pediatrics, Sughra Shafi Medical Complex, Sahara Medical College, Narowal, Pakistan. Period: February 2020 to February 2021. Material & Methods: A total of 71 children aged 1 month to 15 years admitted with acute myocarditis were enrolled. Acute myocarditis was labeled as short history of illness in otherwise healthy child, echocardiography evident of left ventricular dysfunctioning, cardiac biomarkers showing cardiac damage as well as electrocardiography showing acute myocarditis. Age was represented as mean and standard deviation whereas qualitative variables like gender, area of residence and clinical features were shown as frequency and percentages. Results: Out of a total of 71 children, there were 38 (53.5%) were male. Median age was recorded to be 16.6 months. Majority of the cases, 42 (59.2%) belonged to rural areas of residence. Tachycardia was the commonest clinical feature noted in 65 (91.5%) children, irritability was seen in 50 (70.4%), tachypnea in 48 (67.6%) while poor feeding was noted 44 (62.0%) children. Hepatomegaly was noted in 39 (54.9%) children. Hypotension was recorded in 35 (49.3%) children. Conclusion: Male predominance was seen among children presenting with acute myocarditis. Tachycardia, irritability, tachypnea and poor feeding were the commonest clinical features observed.

Transition of acute myocarditis to dilated cardiomyopathy occurs in approximately 20% of patients within a follow-up period of 33 months. Recent research has revealed the adverse prognostic impact of several clinical parameters for this scenario. Acute myocarditis and its sequelae dilated cardiomyopathy and inflammatory cardiomyopathy are often caused by viral infections. Histological evaluation of endomyocardial biopsies is critical for the diagnosis of the cardiomyopathy entity and for the clinical management of around 20% of the patients. Additionally, contemporary diagnostic procedures of endomyocardial biopsies are indispensable for the selection of inflammatory cardiomyopathy patients who will likely benefit from immunosuppression or antiviral (interferon) treatment. Immunoadsorption, with subsequent immunoglobulin substitution, is a further promising immunomodulatory treatment option for dilated cardiomyopathy patients, targeting primarily the anticardiac autoantibodies. Cardiac magnetic resonance has emerged as a valuable diagnostic approach for myocarditis and pericarditis. Myocardial late gadolinium enhancement has been associated with adverse outcome and sudden cardiac death. Bridging of the first 3 months with a wearable cardioverter–defibrillator, until a definitive decision on the implantation of an implantable cardioverter–defibrillator, is a growingly recognized cornerstone in the clinical management of patients with acute myocarditis with depressed left ventricular ejection fraction of <40% and new-onset dilated cardiomyopathy, respectively. Acute pericarditis is labelled idiopathic or suspected viral without adequate proof of the respective aetiology. Non-steroidal anti-inflammatory drugs and colchicine are proven and safe therapeutic mainstays for pericarditis, including the first attack. Pericardiocentesis is a lifesaving treatment of cardiac tamponade. Pericardioscopy and epicardial biopsies can contribute to the aetiological differentiation of pericardial effusions.

AbstractWe report of a 26-year-old female patient who was referred to our centre with congestive heart failure (CHF). Acute myocarditis with a high Parvovirus B19 virus load was diagnosed by myocardial biopsy. CHF improved after start of ramipril 5 mg/d, metoprolol, diuretics, immunoglobins, and a 24-hour infusion of levosimendan. Soon after initiation of medical therapy, the patient started to expectorate bronchial casts with varying frequencies (three times per week to five times daily). Thorough pneumological workup, including histology of the casts, microbiology, and a CT scan of the lungs, did not reveal any cause for bronchial cast formation. Inhalative corticoids were started without any benefit. Two years later, cardiac catheterisation demonstrated normalised left ventricular function. LV end-diastolic pressure, however, was still elevated at 14 mmHg. Endomyocardial biopsies at this time were negative for virus genome. Finally, we changed afterload reduction therapy from ramipril to candesartan. Within 24 hours, expectoration of bronchial casts terminated. Four weeks later, re-exposition to ramipril prompted immediate re-appearance of cast formation, which again stopped with switching back to candesartan. Finally, we were to prove that treatment with ramipril resulted in bronchial cast formation in this patient.

Giant Cell Myocarditis

Background. Idiopathic giant cell myocarditis (GCM) has a fulminant course and typically presents in middle-aged adults with acute heart failure or ventricular arrhythmia. It is a rare disorder which involves T lymphocyte-mediated myocardial inflammation. Diagnosis is challenging and requires a high index of suspicion since therapy may improve an otherwise uniformly fatal prognosis. Case Summary. A previously healthy 54-year-old female presented with hemodynamically significant ventricular arrhythmia (VA) and was found to have severe left ventricular dysfunction. Cardiac MRI demonstrated acute myocarditis, and endomyocardial biopsy showed giant cell myocarditis. She was treated with combined immunosuppressive therapy as well as guideline-directed medical therapy. A secondary prevention implantable cardioverter defibrillator (ICD) was implanted. Discussion. GCM is a rare, lethal myocarditis subtype but is potentially treatable. Combined immunosuppression may achieve partial clinical remission in two-thirds of patients. VA is common, and patients should undergo ICD implantation. More research is needed to better understand this complex disease. Learning Objectives. Giant cell myocarditis is an incompletely understood, rare cause of myocarditis. Patients present predominately with heart failure and dysrhythmia. Diagnosis is confirmed by histopathology, and immunosuppression may improve outcomes. ICD implantation should be considered. In the absence of treatment, prognosis is poor with a median survival of three months.
