Acute Myocarditis Complicating Covid-19 mRNA Vaccination

Abstract

Vaccination against covid-19 is effective element to combat the Pandemic worldwide. Acute Myocarditis is one of the side effects of Covid mRNA especially after second vaccine in young adults and adolescent males. The incidence is estimated 2 cases pro 100,000 mRNA vaccines.43 years old presented in outpatient with Chest discomfort and Dyspnoea 5 days after second mRNA(Pfizer): No History of Diarrhoea or common cold in previous 2 Months .EKG narrow complex QRS, T wave Inversion V1 to V6.Echo: apical Hypokinesie, without Impairment of Ejection fraction. After admission In hospital, elevated inflammation parameter (Leucocytosis 12, CRP 34)Coronarangiography: Normal CoronariesThe patient was released but after 2 weeks presented again with progressive Dyspnoea (NYHA II), EKG typical left bundle branch block with QRS duration of 158 ms
Echo: global Hypokinesia, severely impaired ejection fraction; LV-EF 25% cardiac MRI: Myocardial Edema, Hyperemia early after contact injection. with severely impaired ejection fraction.
