Endocardial fibroelastosis

Endocardial fibroelastosis (EFE) is a rare cardiac condition which is classically described in the paediatric population (typically ~ 1st two years). It is one of the causes for infants to present with unexplained heart failure.

Pathology

The condition results from increasing amounts of fibrous an elastic tissue affecting the endocardium as well as the sub endocardium. This then causes diffuse thickening with subsequent impairment of myocardial contractility.

Radiographic features

Ultrasound / Echocardiography

* may show a strongly echogenic myocardium 3
* may also show ancillary features such as cardiomegaly and evidence of hydrops fetalis as a result of cardiac failure.

Associations

* mitral valve abnormalities : e.g mitral regurgitation
