Immune Checkpoint Inhibitor-Related Stress Cardiomyopathy: Differential Diagnosis and Key Role of Cardiac Imaging.

ABSTRACT: A 76-year-old man with stage IV urothelial carcinoma who was receiving atezolizumab presented with dyspnea, elevated cardiac biomarkers, new negative T waves, and left ventricular apical akinesia. Coronary angiography results were normal. Immune checkpoint inhibitor-related myocarditis was suspected, and high-dose corticosteroid treatment was started. Cardiac magnetic resonance showed apical edema, suggesting stress cardiomyopathy. (Level of Difficulty: Beginner.).
