From COVID-19 to influenza A - recurrent viral myocarditis and successful immunosuppressive therapy: A case report and review of literature

Figure 1 Multimodal assessment of the patient during coronavirus disease 2019 related myocarditis. A: The 12-lead electrocardiogram at admission revealed sinus tachycardia and ST-segment elevation in the inferolateral leads, without reciprocal ST-segment depression in the corresponding leads; B: Chest computed tomography scan performed during coronavirus disease 2019 infection, revealing bilateral ground-glass opacities and consolidations; C: Echocardiographic apical four chambers view during cardiogenic shock; D-I: Cardiac magnetic resonance revealed an area of edema in the mid-basal inferior, inferolateral and lateral walls and a non-ischemic late gadolinium enhancement pattern with thin meso-/subepicardial striae in the inferior and inferolateral walls of left ventricle.

Figure 2 Multimodal assessment of the patient during influenza related myocarditis. A: 12-lead electrocardiogram showing sinus tachycardia with repolarization abnormalities (negative T waves) in the inferior and lateral leads; B: Pulsed-wave Doppler echocardiography demonstrating a reduced left ventricular outflow tract velocity time integral and stroke volume; C: Chest radiography demonstrated no evidence of active parenchymal lesions and bilaterally clear costophrenic angles; D-J: Cardiac magnetic resonance showing diffuse subepicardial edema and meso-subepicardial late gadolinium enhancement in the inferior and inferolateral walls of the left ventricle.
