ANALYSIS OF REGIONAL LEFT VENTRICULAR WALL MOTION IN PRIMARY ENDOCARDIAL FIBROELASTOSIS

Abstract

We performed cineventriculography to evaluate the regional left ventricular wall motion in 7 cases of endocardial fibroelastosis (EFE). For controls, we also evaluated that of 7 cases with other endomyocardial diseases and 10 cases of small shunt VSD.
In EFE, left ventricular end diastolic volumes increased and global ejection fractions decreased significantly, but cardiac indexes were preserved. There were global reductions in left ventricular wall motion especially in posterobasal, inferior, septal and posterolateral regions, but the wall motion around the anterolateral region was relatively preserved in surviving cases. Thus, reduction of anterolateral wall motion is predictive of poor outcome.
