Review Case ReportsTakotsubo Cardiomyopathy presenting with different morphological patterns in the same patient: a case report and review of the literature.
Takotsubo Cardiomyopathy is characterized by transient left ventricular systolic dysfunction, which often mimics a myocardial infarction and is usually triggered by emotional or physical stress. There are four variants of Takotsubo Cardiomyopathy, based on the affected left ventricular area. ⋯ Classical and reverse Takotsubo Cardiomyopathy due to different stressors have been reported in the literature individually, but up to our knowledge, both variants of Takotsubo Cardiomyopathy occurring in the same patient has not been reported previously.

Case ReportsImmunomodulatory treatment of immune checkpoint inhibitor-induced myocarditis: Pathway toward precision-based therapy.
Immune checkpoint inhibitor (ICI)-induced myocarditis carries a poor prognosis and is not fully understood. Similar to lymphocytic myocarditis and acute cellular rejection in heart transplant, ICI-induced myocarditis requires immune suppressive strategies. We aimed to describe ICI-induced myocarditis by presenting findings of comprehensive cardiovascular evaluations and outcomes of patients following a therapeutic approach similar to autoimmune disorders or allograft transplant rejection, and to discuss the molecular basis of the benefits of immune modulation and statins in ICI-myocarditis. ⋯ Cancer therapy was resumed in all patients. One patient expired 10 months after the myocarditis episode due to advanced malignancy; two patients were alive, free of heart failure symptoms and cancer progression, at 1-year follow-up, and 1 patient was rechallenged with ICI. We suggest that treatment with IVIG and statins may allow for a prompt resumption of anti-cancer therapy (including ICI) and improve outcomes.
