Survival in biopsy-proven myocarditis: a long-term retrospective analysis of the histopathologic, clinical, and hemodynamic predictors.

Objective: We hypothesized that histopathology predicts survival without cardiac transplantation in patients with biopsy-proven myocarditis.

Background: The role of endomyocardial biopsy in diagnosing myocarditis remains controversial. Histopathology has been integrated with clinical and hemodynamic features to predict prognosis.
