There is limited data on the pattern and severity of myocardial injury in patients with COVID-19 vaccination associated myocarditis.We aimed to define damage occurring after BNT162b2 vaccination, raise awareness about adverse reactions developing determine patterns scope Cardiac magnetic resonance imaging (MRI) findings.A total 9 diagnosed vaccine-associated myopericarditis were followed up.The mean age patient at diagnosis was 15.3 ± 1.0 (range: 14-17) years, all male. Seven presented myocarditis symptoms their second vaccine dose, one pericarditis his first other booster dose. The median time presenting hospital 3 2-22) days. (77.7%) had abnormal electrocardiography (ECG) findings, most prevalent finding diffuse ST-segment elevation. Initial cardiac MRI results patients, where 8 (88.8%) late gadolinium enhancement, 5 (55.5%) edoema. Three showed local left ventricular wall-motion abnormalities. In follow-up MRIs 3-6 months later, edoema present 2 (28.5%) while enhancement (7/7, 100%, did not have control time). Hypokinetic segments still patients. No negative events observed short-term any patient.Further evaluation larger multicenter studies are needed clinical significance persistent
