Flow disturbances and progression of endocardial fibroelastosis - a case report.
Endocardial fibroelastosis (EFE) is described as thickening of the endocardium and is associated with hypoplastic left heart syndrome (HLHS). The stimulus for EFE and the mechanism for recurrence and/or progression need to be investigated. In this report, we describe the case of a 4-year-old HLHS patient who underwent several surgeries with EFE resections due to recurrence of EFE. EFE recurrence was associated with flow disturbances due to valvar defects. At her latest follow-up 7 months after the last surgery, competent valves and no EFE were identified on all imaging study.
