Prognostic value of the electrocardiogram in endocardial fibroelastosis
Insights
Electrocardiogram (ECG) patterns can predict survival in children with endocardial fibroelastosis. An initial ECG showing an 'infarct pattern' indicates a poor prognosis, often preceding death.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Pathology
Background:
- Endocardial fibroelastosis (EFE) is a rare condition causing congestive heart failure in children.
- Clinical features of EFE have varied prognostic indicators.
- Electrocardiographic (ECG) findings in EFE require further investigation for their prognostic value.
Purpose of the Study:
- To determine if specific clinical features, particularly ECG patterns, correlate with survival in pediatric patients diagnosed with endocardial fibroelastosis.
- To assess the prognostic significance of the initial electrocardiogram in children with EFE.
Main Methods:
- A retrospective review of nine pediatric patients with endocardial fibroelastosis admitted for congestive heart failure.
- Analysis of clinical features, focusing on serial electrocardiograms (ECGs).
- Correlation of ECG patterns with patient outcomes (death or discharge).
- Necropsy confirmation of diagnosis in a subset of patients.
Main Results:
- The initial electrocardiogram (ECG) pattern was the only clinical feature significantly correlated with survival.
- All children who died presented with an initial ECG showing a delayed transition zone and anterior force loss (an 'infarct pattern').
- Progression of these ECG changes was observed before death in some cases.
- Necropsy findings confirmed extensive myocardial fibrosis and thinning in EFE patients.
Conclusions:
- An 'infarct pattern' on the initial ECG is a significant negative prognostic indicator in children with endocardial fibroelastosis.
- This ECG finding is strongly associated with mortality in pediatric EFE.
- Electrocardiography plays a crucial role in assessing prognosis for children with EFE.
Abstract:
Nine children with endocardial fibroelastosis were followed from the time of admission with congestive heart failure until either death or discharge. Review of multiple clinical features showed that only the electrocardiographic pattern could be correlated with death or survival. The presence of a delayed transition zone with anterior force loss on the initial electrocardiogram ('infarct pattern') was noted in all the children who died. Progression of these changes with a pattern of anterolateral 'infarct' in two and inferior wall 'infarct' in two occurred before death. Necropsy on three of the four children confirmed the diagnosis of endocardial fibroelastosis. There was extensive fibrosis and thinning of the left ventricular myocardium as well as involvement of the mitral valve structures. Review of published cases supports the view that an 'infarct' pattern in a child with endocardial fibroelastosis is usually associated with death and that this pattern is a negative prognostic sign for survival.
