Basal short-axis 1.5-T cardiac MR images demonstrate (A) subepicardial late gadolinium enhancement at the basal inferior and inferior lateral wall (red arrows), with corresponding (B) hyperintensity on T2-weighted image (orange arrows), (C) abnormal high regional native T1 (1123 msec, blue arrows [upper reference range, 960 msec]), and (D) abnormal high regional T2 (58 msec, green arrows [upper reference range, 51 msec]). These findings are in keeping with acute myocarditis based on the revised Lake Louise criteria. Global systolic function was impaired (left ventricular ejection fraction, 48%), with hypokinesis of the basal inferolateral wall. (E) Speckle-tracking echocardiography-based global longitudinal strain demonstrates reduced strain involving most basal segments (global longitudinal strain, −18%).

Myocardial Injury Pattern at MRI in COVID-19 Vaccine-associated Myocarditis

Keywords Echocardiography, MR-Functional Imaging, MRI, Cardiac Global systolic function was impaired (left ventricular ejection fraction, 48%), with hypokinesis of the basal inferolateral wall (Movies 1, 2). Speckle-tracking echocardiography-based global longitudinal strain demonstrates reduced strain involving most basal segments (global longitudinal strain, −18%) (Fig E). The patient was treated with prednisone, bisoprolol, and colchicine, and symptoms resolved within 10 days
