Introduction COVID-19 disease has caused a global health and economic crisis. The introduction of the different COVID-19 vaccines has resulted in a significant decrease in the morbidity and mortality associated with this disease. Adverse effects have been reported, including cardiological ones such as myocarditis or pericarditis after administration. Likewise, tyrosine kinase inhibitor drugs such as osimertinib used in lung cancer patients with epidermal growth factor receptor (EGFR) mutation are associated with heart failure or prolongation of the QT interval.Case report 62-year-old woman diagnosed in September 2019 of lung adenocarcinoma stage IV with bilateral lung and lymph node involvement, carrier of an EGFR mutation (Ex19Del) on treatment with osimertinib. She attended emergency department for fever and hypotension 24 h after administration of the third dose of Moderna® COVID-19 vaccine in the context of acute myocarditis with evidence of severe left ventricular (LV) dysfunction in cardiogenic shock. She required vasoactive support, non-invasive mechanical ventilation, corticotherapy, immunoglobulins and subsequent ventricular support with Impella, with improvement of the clinical picture after 3 days. Cardiac magnetic resonance imaging (MRI) showed evidence of global myocardial oedema compatible with acute myocarditis. Coronary CT showed a lesion in the anterior descending coronary artery requiring revascularization. A few days later, she presented febrile symptoms with isolation of Staphylococcus aureus in the central line catheter and antibiotherapy with cloxacillin was started, with subsequent resolution of the infectious symptoms.Conclusion This is an exceptional and controversial case of fulminant myocarditis probably related to the Modern COVID-19 vaccine in a patient diagnosed with metastatic lung adenocarcinoma on treatment with osimertinib. An increasing number of cases of myocarditis and pericarditis have been reported following vaccination with COVID-19 mRNA vaccines. In addition, retrospective data have shown an increased risk of QT prolongation and heart failure in patients treated with tyrosine kinase inhibitors. Hence, the need for close monitoring of cardiac function during treatment of these patients. Future studies will be necessary to evaluate unknown adverse reactions of these vaccines and their possible interaction with other antineoplastic drugs.
