fibroelastosis

 [fi″bro-e″las-to´sis]
overgrowth of fibroelastic elements.
endocardial fibroelastosis a condition characterized by left ventricular hypertrophy and conversion of the endocardium into a thick fibroelastic coat, with ventricular capacity sometimes reduced, but often increased, leading to heart failure.

en·do·car·di·al fi·bro·e·las·to·sis

, endomyocardial fibroelastosis [MIM*305300, MIM*226000]
1. a congenital condition characterized by thickening of the left ventricular wall endocardium (chiefly due to fibrous and elastic tissue), thickening and malformation of the cardiac valves, subendocardial changes in the myocardium, and hypertrophy of the heart; chief symptoms are cyanosis, dyspnea, anorexia, and irritability;

endocardial fibroelastosis

[fī′brō·ē′lastō′sis]
Etymology: Gk, endon + kardia, heart; L, fibra, fiber; Gk, elaunein, to drive, osis, condition
an abnormal condition characterized by the development of a thick, fibroelastic endocardium that can cause failure of the heart to pump blood.

endocardial fibroelastosis

A rare congenital heart disease more commonly seen in children under age 2, which is characterised by endocardial fibrosis.

Aetiology
Uncertain; EFE has been associated with infections (especially viral), cardiomyopathy, immune diseases, congenital malformations and lightning.

en·do·car·di·al fi·bro·e·las·to·sis

, endomyocardial fibroelastosis (endō-kahrdē-ăl fībrō-ē-las-tōsis, endō-mī-ō-)
Condition characterized by thickening of the left ventricular wall endocardium (chiefly due to fibrous and elastic tissue), thickening and malformation of the cardiac valves, subendocardial myocardial changes, and cardiac hypertrophy; chief symptoms are cyanosis, dyspnea, anorexia, and irritability.

endocardial

1. situated or occurring within the heart.
2. pertaining to the endocardium.

endocardial cushions
elevations on the atrioventricular canal of the embryonic heart which later help partition the heart. Defective development contributes to several cardiac anomalies, including ventricular septal defect and atrioventricularis communis.
endocardial fibroelastosis
the accumulation of collagen and elastic fibers in the endocardium, together with left ventricular hypertrophy dilatation, is an inherited, primary cardiac anomaly in Burmese cats.
endocardial fibrosis
occurs with cardiac dilatation or hypertrophy. In cats, leads to restrictive cardiomyopathy.
endocardial splitting
a complication of chronic valvular insufficiency and congestive cardiomyopathy in dogs. May be partial or full thickness; can occur on the interatrial septum, producing an acquired septal defect, or elsewhere causing hemopericardium.
endocardial tube
formed from the cardiogenic plate in the developing embryo, this forms the primordium of the truncus arteriosus, the atrium and the ventricles; it is later invested by the myocardium.

fibroelastosis

overgrowth of fibroelastic elements.
