Myocarditis Secondary to COVID 19 Infection: A Case-Report

Abstract

Introduction: Coronavirus disease 2019 (COVID 19) is an emerging viral infection caused by the strain of coronavirus SARS-CoV-2, primarily affecting the respiratory system. However, it can be responsible for heart damage. The aim of this work was to report a case of symptomatic myocarditis in a 53-year-old patient. Patient and Observation: We report the case of a 53-year-old patient with no particular history or cardiovascular risk factor found who had consulted in June 2020 in a hospital for dyspnea, dizziness and palpitations in whom the electrocardiogram had demonstrated ventricular tachycardia. The echocardiography was normal and coronary artery disease was ruled out on coronary angiography and antiarrhythmic treatment allowed it to regress. Two months later, after a break in therapy, this tachycardia recurred despite several electrical and chemical cardioversions. Subsequently, myocarditis was suspected. This motivated the realization of a cardiac magnetic resonance imaging (MRI) which came back in favor of myocarditis. As part of the etiological research, RT-PCR and COVID 19 serology were requested and the serology returned positive for IgG. Conclusion: COVID 19 disease is known for its respiratory manifestations. However, several cases of cardiac involvement, in particular myocardial damage, have been described and among these, a considerable proportion of arrhythmias. They can be multifactorial in origin, due to the virus itself, or the prolongation of the QT interval from various drug therapies. These arrhythmias are the source of sudden death, hence the interest of RT-PCR and COVID 19 serology, but also the need for early and appropriate management, as well as long-term monitoring of patients. cured patients.
