Extensive Loss of Myocardium due to Lymphocytic Fulminant Myocarditis: An Autopsy Case Report of a Patient with Persistent Cardiac Arrest for 25 Days

Abstract

We herein report the histological findings of a patient who had progressed to persistent cardiac arrest for 25 days due to lymphocytic fulminant myocarditis despite mechanical circulatory support (MCS). There were few residual cardiomyocytes, and extensive replacement fibrosis was present. Therefore, improvement of the cardiac function for this patient was considered improbable. Further research is warranted to improve predictions for the recovery of the cardiac function and optimize MCS strategies for patients with fulminant myocarditis.
