Objective: To search for the degree of ventricular
hypertrophy and the condition of ventricular systolic and diastolic
function in children with endocardial fibroelastosis (EFE).
Methods: The left ventricular mass index (LVMI), systolic function and
diastolic function were determined in 16 children with EFE and 17
age-matched normal children by Acuson 128XP color echocardiography
instrument.
Results: The LVMI was increased, and the left
ventricular systolic function was decreased in the patients with EFE. The
reduction of he left ventricular diastolic function in children with EFE
included the drop of E, AC, E/A, EFF and 1/3EFF, extension of IVRT,
increase of A and AFF. The indexes above were detected in 3 children with
EFE whose clinical symptoms and signs had disappeared, and cardiothoracic
ratio(CTR) was less than 0.55 after treatment for more than 1 year. The
results showed that the EF and FS basically recovered to normal levels. The
diastolic function was only partly improved. The LVMIs in 3 patients with
EFE were higher than the normal group though it was already obviously
decreased.
Conclusion:
The ventricular
hypertrophy was obvious in the children with EFE. The degree of ventricular
hypertrophy was noninvasively clearly understood by LVMI. There was a
reduction found not only in systolic function but also in diastolic
function mainly expressed by decrease of left ventricular relaxation in the
children with EFE. The clinical recovery must be more fully evaluated not
only by the improvement of clinical symptoms, signs and chest X-ray study
but also by the detection of the cardiac function and LVMI.
