An Atypical Presentation of Fulminant Myocarditis Secondary to COVID-19 Infection

Fulminant Myocarditis with SARS-CoV-2 Infection: A Narrative Review from the Case Studies

One of the severe complications of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is myocarditis. However, the characteristics of fulminant myocarditis with SARS-CoV-2 infection are still unclear. We systematically reviewed the previously reported cases of fulminant myocarditis associated with SARS-CoV-2 infection from January 2020 to December 2022, identifying 108 cases. Of those, 67 were male and 41 female. The average age was 34.8 years; 30 patients (27.8%) were ≤20 years old, whereas 10 (9.3%) were ≥60. Major comorbidities included hypertension, obesity, diabetes mellitus, asthma, heart disease, gynecologic disease, hyperlipidemia, and connective tissue disorders. Regarding left ventricular ejection fraction (LVEF) at admission, 93% of the patients with fulminant myocarditis were classified as having heart failure with reduced ejection fraction (LVEF ≤ 40%). Most of the cases were administered catecholamines (97.8%), and mechanical circulatory support (MCS) was required in 67 cases (62.0%). The type of MCS was extracorporeal membrane oxygenation (n = 56, 83.6%), percutaneous ventricular assist device (Impella®) (n = 19, 28.4%), intra-aortic balloon pumping (n = 12, 12.9%), or right ventricular assist device (n = 2, 3.0%); combination of these devices occurred in 20 cases (29.9%). The average duration of MCS was 7.7 ± 3.8 days. Of the 76 surviving patients whose cardiac function was available for follow-up, 65 (85.5%) recovered normally. The overall mortality rate was 22.4%, and the recovery rate was 77.6% (alive: 83 patients, dead: 24 patients; outcome not described: 1 patient).

Severe COVID-19-associated myocarditis with cardiogenic shock - management with assist devices - a case report & review

BACKGROUND

Primary viral myocarditis associated with severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) infection is a rare diagnosis.

CASE PRESENTATION

We report the case of an unvaccinated, healthy patient with cardiogenic shock in the context of a COVID-19-associated myocarditis and therapy with simultaneous veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and percutaneous left ventricular decompression therapy with an Impella. The aim of this review is to provide an overview of therapeutic options for patients with COVID-19-associated myocarditis.

CONCLUSIONS

The majority of patients required a combination of two assist devices to achieve sufficient cardiac output until recovery of left ventricular ejection fraction. Due to the rapid onset of this fulminant cardiogenic shock immediate invasive bridging therapy in a specialized center was lifesaving.

COVID-19 Related Myocarditis in Adults: A Systematic Review of Case Reports

Despite the progress of its management, COVID-19 maintains an ominous condition which constitutes a threat, especially for the susceptible population. The cardiac injury occurs in approximately 30% of COVID-19 infections and is associated with a worse prognosis. The clinical presentation of cardiac involvement can be COVID-19-related myocarditis. Our review aims to summarise current evidence about that complication. The research was registered at PROSPERO (CRD42022338397). We performed a systematic analysis using five different databases, including i.a. MEDLINE. Further, the backward snowballing technique was applied to identify additional papers. Inclusion criteria were: full-text articles in English presenting cases of COVID-19-related myocarditis diagnosed by the ESC criteria and patients over 18 years old. The myocarditis had to occur after the COVID-19 infection, not vaccination. Initially, 1588 papers were screened from the database search, and 1037 papers were revealed in the backward snowballing process. Eventually, 59 articles were included. Data about patients' sex, age, ethnicity, COVID-19 confirmation technique and vaccination status, reported symptoms, physical condition, laboratory and radiological findings, applied treatment and patient outcome were investigated and summarised. COVID-19-related myocarditis is associated with the risk of sudden worsening of patients' clinical status, thus, knowledge about its clinical presentation is essential for healthcare workers.

Clinical variants of myocardial involvement in COVID-19-positive patients: a cumulative experience of 2020

Myocardial injury, diagnosed by troponin elevation, is common in COVID-19 patients, but cardiac involvement with clinical manifestations occurs less frequently. We analyzed the literature on COVID-19 (2020) and systematically reviewed the cases where individual patient data were presented. We searched PubMed and Google Scholar for "COVID," "COVID-19," and "coronavirus" in combination with "myocarditis," "heart failure," "takotsubo," "cardiomyopathy," and "cardiogenic shock." We identified 90 cases of COVID-19 with myocardial involvement, mean age 52.9 ± 18.3 years, 54.5% males. Of them, 55 survived (61.1%), 20 died (22.2%), and in 15 (16.7%) the outcome was unknown at the time of publication. Among patients with known outcome, mortality was 26%. The nadir LVEF was 31.7 ± 13.1% and recovered to 50.1 ± 16.0%. Pericardial effusion was a common finding, reported in 21 (23.3%) of patients, including moderate size effusion in 8.9% and large in 7.8%. The effusion caused tamponade in 11 (12.2%) of patients. Out of 83 patients who experienced a decrease in LVEF, 30 could be classified as takotsubo syndrome. The takotsubo patients were older than those with myocarditis, and with relatively high proportion of males. About one third of the cases was complicated by cardiogenic shock. Myocardial involvement in COVID-19 patients most often presents as a new, rapid decrease in LVEF, although normal LVEF or takotsubo-like wall motion pattern does not rule out myocarditis. Moderate and large pericardial effusion is common, and cardiac tamponade occurs in 12.2% of patients. Cardiogenic shock develops in one third of the patients. Mortality appears to be high at 26%.

Comorbidities and Symptomatology of SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2)-Related Myocarditis and SARS-CoV-2 Vaccine-Related Myocarditis: A Review

Myocarditis is an inflammatory disease of the heart muscle, with manifestations that include myocardial infarction, arrhythmia, and even sudden death. The primary etiology of myocarditis is a viral infection, with studies demonstrating that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to myocarditis. This enzyme is involved in many body tissues, including the gastrointestinal system and the cardiac system. This enzyme is responsible for converting angiotensin I to angiotensin II in the renin-angiotensin system of our body. This review aims to characterize the symptomatology and comorbidities of males, females, and pediatric patients who developed the SARS-CoV-2-related myocarditis (SARS-CoV-2RM) or the SARS-CoV-2 vaccine-related myocarditis (SARS-CoV-2VRM). From July 10 to July 20, 2021, a PubMed database search for “SARS CoV-2 Related Myocarditis” was conducted. From July 21 to July 30, 2021, the search for “SARS CoV-2 Vaccine Related Myocarditis” was conducted. The search completed was specific for title/abstract fields using keywords “Covid-19” AND “Myocarditis” AND “Vaccine” and specifying “Males” or “Females”, respectively. Inclusion criteria included articles discussing comorbidities and symptomatology. Exclusion criteria included autopsy/postmortem reports, letters to the editor, retrospective studies, and observational studies. In the end, 49 articles were found and included in this review. We found that 27 of 40 pediatric patients with SARS-CoV-2RM presented with gastrointestinal symptoms, and 12 of 40 pediatric patients had no comorbidities. In female cases, eight of 12 patients with SARS-CoV-2RM presented with noncardiac symptoms, and only four of 12 had comorbidities such as asthma, diabetes, and obesity. In male patients with SARS-CoV-2RM, 10 of 12 presented with respiratory and/or cardiac symptoms, and seven of 12 had cardiac and/or diabetic comorbidities. Furthermore, 22 of 31 male patients with SARS-CoV-2VRM presented with chest pain with no previous comorbidities; four of six females with SARS-CoV-2VRM presented with chest pain, and three of six females had no comorbidities; and seven of 11 pediatric patients with SARS-CoV-2VRM had no comorbidities, but 11 of 11 pediatric patients presented with chest pain. In conclusion, males, females, and pediatric patients with previous SARS-CoV-2VRM showed mostly chest pain with no comorbidities. Males presenting with SARS-CoV-2RM showed mostly respiratory and cardiac symptoms with cardiac and diabetic comorbidities. Females with SARS-CoV-2RM described various symptoms from flu-like, respiratory, to cardiac and had no previous comorbidities. The bulk of pediatric patients with SARS-CoV-2RM mainly presented with GI symptoms and no past comorbidities. More studies are needed to determine the clinical presentation and risk factors that lead to SARS-CoV-2RM and SARS-CoV-2VRM.

Corticosteroid Therapy in Management of Myocarditis Associated with COVID-19; a Systematic Review of Current Evidence

INTRODUCTION

Myocarditis in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seems to be associated with a higher mortality rate. This study aims to summarize the latest evidence on whether the use of corticosteroids in patients with myocarditis associated with COVID-19 is necessary.

METHODS

We performed an extensive search using a combination of search terms in PubMed, Europe PMC, ProQuest, EBSCOhost, and Google Scholar up to January 2021. Full-text articles that met the predefined inclusion criteria were included in the present study.

RESULTS

The full-texts of 18 articles have been reviewed. Thirteen out of the eighteen (72%) patients who got corticosteroid administration experienced major clinical improvements during follow-up while the other five (28%) were experiencing uneventful events. The mean age of the reported patients was 47.8±13.2 years. There was no gender predominance. Most of the reported cases were from USA (39%) followed by Spain, China, and UK (11% each), while Brazil, Colombia, France, Belgium, and Italy contributed one case each. Various corticosteroids were used but the most commonly applied were methylprednisolone (89%), hydrocortisone (5.5%), and prednisolone (5.5%). The most common route of administration among the studies was intravenous administration and the duration of treatment varied between one and fourteen days.

CONCLUSION

A review of the currently available literature shows that with the use of corticosteroid agents in treating myocarditis associated with COVID-19, favorable outcomes are attainable. Well-established randomized clinical trials are needed to evaluate the efficacy and safety of using corticosteroids in this condition.

Autoimmune and Rheumatic Manifestations Associated With COVID-19 in Adults: An Updated Systematic Review

Background: Numerous cases of the coronavirus disease 2019 (COVID-19) with autoimmune and rheumatic manifestations have been reported. Despite the available reviews that summarized its autoimmune/rheumatic manifestations, a systematic approach is still lacking. Therefore, we conducted a comprehensive systematic review in order to give an overview upon these rare but clinically significant manifestations.

Methods: We performed a literature search of PubMed and EMBASE as of October 9, 2020. All articles relevant to either systemic or organ-specific autoimmune and rheumatic manifestations potentially associated with COVID-19 were collected. The reviewed literature were limited to adults ≥18 years.

Results: Although most of the existing evidence was based on case reports or case series without a long-term follow-up, a variety of autoimmune/rheumatic manifestations were associated with COVID-19. The manifestations that have a consistent association with COVID-19 include autoimmune cytopenia, cutaneous vasculitis, encephalitis, and Guillain-Barre syndrome. Such association is conflicting as regards to antiphospholipid syndrome, hemophagocytic lymphohistiocytosis, and myasthenia gravis.

Conclusion: Our systematic review indicated the potential of the COVID-19 virus to trigger a myriad of autoimmune and rheumatic manifestations, which should be considered amid global efforts to combat COVID-19.
