Cardiogenic shock revealing myocarditis after mRNA vaccination against covid-19: Case report and brief review for the first case in Morocco.

ABSTRACT:

Introduction

and importance: After its unexpected effectiveness in the clinical trials, the anti-COVID-19 vaccine type mRNA was launched on December 11, 2020, but a few months later, several reports of post-mRNA vaccination myocarditis were published, but without any proven causal link.

Case presentation

We report the case of a 14-year-old teenager admitted to the emergency department for a cardiogenic shock, the patient mentioned that he had an anti-COVID 19 vaccination 10 days before his admission. First, the vasoactive drugs had stabilized the patient; the troponins came back highly favorable but later confirmed myocarditis by magnetic resonance imaging. In this sense an etiological analysis was made and it came back without any particularities, leaving us relating the myocarditis to the vaccination.

Clinical discussion

Post-vaccination myocarditis is a rare event, with very few reports in the literature. After the introduction of COVID vaccination, several reports were published, mostly after the mRNA vaccine. Until now, no causal link has been proven, so we need to have more reports in this sense to have a better knowledge of this phenomenon.

Conclusion

Until we obtain a more precise explanation of the mechanism of myocarditis after vaccination with the anti-COVID-19 vaccine, all symptoms suggesting myocarditis should be systematically monitored during the first 7 days after vaccination.

Cardiogenic shock due to probable SARS-CoV-2 myocarditis-a case report.

Project description:BackgroundSince the start of the COVID-19 pandemic, many case reports have been presented describing different cardiac symptoms due to the SARS-CoV-2 infection. However, severe cardiac failure due to COVID-19 seems to be rare.Case summaryA 30-year-old woman presented with COVID-19 and cardiogenic shock due to a lymphocytic myocarditis. Since she deteriorated under treatment with inotropes, she was referred to our centre, and veno-arterial extracorporeal life support was started. Subsequently, the aortic valve only opened sporadically, and spontaneous contrast appeared in the left ventricle (LV), pointing towards difficulties with unloading LV. Therefore, an Impella for venting the LV was implanted. After 6 days of mechanical circulatory support, her heart function recovered. All support could be weaned, and 2 months later, she had made a full recovery.DiscussionWe presented a patient with severe cardiogenic shock due to an acute virus-negative lymphocytic myocarditis associated with a SARS-CoV-2 infection. Since the precise aetiology of SARS-CoV-2-related myocarditis remains to be elucidated and no virus could be detected in the heart, a causal relationship remains speculative.

Case Report: Acute Fulminant Myocarditis and Cardiogenic Shock After Messenger RNA Coronavirus Disease 2019 Vaccination Requiring Extracorporeal Cardiopulmonary Resuscitation.

Project description:Recently, myocarditis following messenger RNA (mRNA) coronavirus disease 2019 (COVID-19) vaccination has become an important social issue worldwide. According to the reports so far, myocarditis related to mRNA COVID-19 vaccination is rare and usually associated with a benign clinical course without intensive care or any sequelae of fulminant myocarditis. Here, we report a case of acute fulminant myocarditis and cardiogenic shock after the mRNA COVID-19 vaccination, requiring extracorporeal cardiopulmonary resuscitation. Clinicians should keep in mind the possibility of progression to fulminant myocarditis in patients who presented with suggestive symptoms or signs of myocarditis after the COVID-19 vaccination.

Case report of cardiogenic shock in COVID-19 myocarditis: peculiarities on diagnosis, histology, and treatment.

Project description:BackgroundThe year 2020 was dramatically characterized by SARS-CoV-2 pandemic outbreak. COVID-19-related heart diseases and myocarditis have been reported.Case summaryA 45-year-old healthy male was admitted to the intensive care unit of our hospital because of cardiogenic shock. A diagnosis of COVID-19 infection and myocarditis was done. We present here several peculiarities about diagnostic workup, myocardial histological findings, choice of treatment, and the patient clinical course at 3 and 8 months of follow-up.DiscussionCOVID-19 myocardial damage and myocarditis are mainly linked to the cytokine storm with mild myocardial inflammatory infiltrate and very unusual platelet microclots in the setting of the microvascular obstructive thrombo-inflammatory syndrome. Counteracting the inflammatory burden with an interleukine-1 inhibitor appeared safe and led to a dramatic and stable improvement of cardiac function.

Myocarditis in COVID-19 presenting with cardiogenic shock: a case series.

Project description:BackgroundSARS-CoV2, also known as COVID-19, is a specific strain of coronavirus that is responsible for an ongoing global pandemic. COVID-19 primarily targets the respiratory system via droplet transmission, causing symptoms similar to influenza, including fever, cough, and shortness of breath. It is now known to impact other organ systems, causing significant cardiovascular and gastrointestinal illness, among others.Case summaryWe describe two cases of COVID-19 induced myocarditis presenting with cardiogenic shock. These cases highlight the importance of understanding the lethal cardiac complications of COVID-19 infection, as well as its presentation, diagnosis, pathophysiology, and potential treatment options. These two cases involve patients without underlying cardiovascular disease risk factors who experienced prolonged symptoms of COVID-19 infection. Both patients presented with cardiogenic shock more than one week after symptom onset and diagnosis. These cases demonstrate the late presentation of myocarditis and cardiogenic shock, treated with corticosteroids and inotropes, with subsequent recovery of cardiac function.DiscussionThe cases highlight the importance of recognizing late presentation viral myocarditis secondary to COVID-19 infection, even in patients without underlying cardiac disease.

A case report of acute heart failure and cardiogenic shock caused by catastrophic antiphospholipid syndrome and lupus myocarditis.

Project description:BackgroundCatastrophic antiphospholipid syndrome and lupus myocarditis are two rare life-threatening conditions.Case summaryWe present a case of a 47-year-old woman admitted in profound cardiogenic shock due to catastrophic antiphospholipid syndrome and lupus myocarditis requiring advanced heart failure therapies, including early mechanical circulatory support. She improved with steroids, immunoglobulins, mycophenolate, and eculizumab.DiscussionThis case highlights the importance of early identification of cardiogenic shock secondary to catastrophic antiphospholipid syndrome and lupus myocarditis, the arrhythmogenic complications of myocarditis, and the subsequent management of the disease progression with mechanical and medical support.

Gastroenteritis and cardiogenic shock in a healthcare worker: a case report of COVID-19 myocarditis confirmed with serology.

Project description:BackgroundCoronavirus disease 2019 (COVID-19) myocarditis is emerging as a component of the hyperactive inflammatory response secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Isolated gastrointestinal symptoms are uncommon presenting features in adults with COVID-19 myocarditis. The availability of antibody testing is a valuable addition to the confirmation of COVID-19, when repeated reverse transcriptase-polymerase chain reaction of nasopharyngeal swabs are negative.Case summaryA young healthcare worker presented with dizziness and pre-syncope, 4 weeks after his original symptoms that included fever, lethargy, and diarrhoea. Despite 2 weeks of isolation, followed by a quiescent spell, his symptoms had returned. Shortly after, he presented in cardiogenic shock (left ventricular ejection fraction 25%), that required vasopressor support, at the height of the COVID-19 pandemic. Cardiac magnetic resonance imaging suggested florid myocarditis. Three nasopharyngeal swabs (Days 1, 3, and 5) were negative for SARS-CoV-2, but subsequent serology (Day 13) confirmed the presence of SARS-CoV-2 IgG. Treatment with intravenous immunoglobulin and glucocorticoids led to full recovery.DiscussionOur case study highlights the significance of the use of the available serological assays for diagnosis of patients presenting late with SARS-CoV-2. Importantly, it supports further research in the use of immunomodulatory drugs for the hyperinflammatory microenvironment induced by COVID-19.

Case Report: Lymphohistiocytic Myocarditis With Severe Cardiogenic Shock Requiring Mechanical Cardiocirculatory Support in Multisystem Inflammatory Syndrome Following SARS-CoV-2 Infection.

Project description:Multisystem Inflammatory Syndrome (MIS) is a novel hyperinflammatory syndrome associated with SARS-CoV-2 infection. It predominantly affects children (MIS-C) a few weeks after a usually asymptomatic SARS-CoV-2 infection and is only rarely seen in adults above 21 years (MIS-A). Only scarce data on histological findings in both pediatric and adult patients has been published so far. An 18-year-old male patient was admitted to hospital in a febrile state, which progressed to severe cardiogenic shock and multi-organ failure requiring extracorporeal life support. Myocardial biopsy revealed small vessel-associated immune cell infiltrates. Diagnosis of MIS-C was made after ruling out all potential differential diagnosis. Use of immunosuppressive treatment with steroids, interleukin-1 blockade and high-dose intravenous immunoglobulins resulted in the patient's full recovery. Multisystem Inflammatory Syndrome (MIS) is a new differential diagnosis of cardiac dysfunction in pediatric and adult patients. The lack of myocardial necrosis differentiates the disease from other viral myocarditis and offers an explanation for the fast response to immunomodulatory therapy and the favorable prognosis. The preceding SARS-CoV-2 infection might only have been mildly symptomatic or even asymptomatic.

Case report: Myocarditis following COVID-19 protein subunit vaccination.

Project description:We report findings in a 34-year-old female patient who presented with fulminant myocarditis 8 days after receiving the first dose of the ZF2001 RBD-subunit vaccine against coronavirus disease 2019 (COVID-19). Autopsy showed severe interstitial myocarditis, including multiple patchy infiltrations of lymphocytes and monocytes in the myocardium of the left and right ventricular walls associated with myocyte degeneration and necrosis. This report highlights the details of clinical presentations and autopsy findings of myocarditis after ZF2001 (RBD-subunit vaccine) vaccination. The correlation between vaccination and death due to myocarditis is discussed.
