Ventricular fibrillation and arrhythmia associated with cardiac fibromas involving both ventricles in a 1.5-year-old girl

This article reports the autopsy findings of a 1.5-year-old girl with no history of previous hospital admission who suddenly collapsed at home. After 45 minutes of resuscitation efforts, the cardiac activity was restored. During hospitalization, she had ventricular arrhythmia and extremely elevated cardiac troponin levels. Internal examination and immunohistochemistry revealed cardiac fibromas of the right and left ventricles and extensive hypoxic myocardial damage. The right ventricular fibroma demonstrated interdigitating and entrapped myocardium visible at the edges and within the central portion of the tumor. The left ventricular fibroma originated in the subepicardial region and propagated towards the endocardium.
