COVID-19 Vaccine-Induced Acute Perimyocarditis: A Case Report

Figures

• 

  Figure 1. Electrocardiogram showing diffuse ST elevations An electrocardiogram showing sinus tachycardia, right axis deviation, and incomplete right bundle branch block. Diffuse ST segment elevations can be seen in leads II, III, aVF, V4, V5, and V6, which are consistent with pericarditis.

• 

  Figure 2. Cardiac MRI showing diffuse subepicardial enhancement of the left ventricular walls with relative sparing of the base, consistent with myocarditis Short-axis cardiac MRI performed at 1.5 T shows myocarditis. The delayed contrast-enhanced image shows diffuse subepicardial enhancement of the left ventricular walls (arrows) with relative sparing of the base.

• 

  Figure 3. Cardiac MRI demonstrates the prolongation of T1 relaxation time in the subepicardial anterolateral and posterolateral walls, consistent with myocardial edema. Short-axis cardiac MRI performed at 1.5 T shows myocarditis. The native T1 map demonstrates prolongation of the T1 (1250 -1350 msec) relaxation time in the subepicardial anterolateral and posterolateral walls (arrows), consistent with myocardial edema.

• 

  Figure 4. Cardiac MRI demonstrates the prolongation of T2 relaxation time in the subepicardial anterolateral and posterolateral walls, consistent with myocardial edema Short-axis cardiac MRI performed at 1.5 T shows myocarditis. The native T2 map demonstrates prolongation of the T2 (60- 65 msec) relaxation time in the subepicardial anterolateral and posterolateral walls (arrows), consistent with myocardial edema.
