OBJECTIVE
To assess the dynamic
changes in left atrial volume by transthoracic three dimensional
echocardiography and compare the results with those obtained by
magnetic resonance imaging (MRI).
DESIGN AND PATIENTS30 healthy
children (15 boys and 15 girls, aged 8 to 13 years) underwent
examination by three dimensional echocardiography and MRI.
METHODSThree dimensional
echocardiography of the left atrium was performed using rotational
acquisition of planes at 18° intervals from the parasternal window
with ECG gating and without respiratory gating. Volume estimation by
MRI was performed with a slice thickness of 4-8 mm and ECG triggering
during breath holding in deep inspiration. A left atrial time-volume
curve was reconstructed in each child.
RESULTSLeft atrial maximum and
minimum volumes averaged 24.0 ml/m2 and
7.6 ml/m2 by three dimensional echocardiography, and
22.1 ml/m2 and 11.9 ml/m2 by MRI. The greater
left atrial minimum volume in the latter was at least in part a result
of breath holding. Dynamic changes in left atrial volume during the
heart cycle were detectable by both methods. The higher temporal
resolution of three dimensional echocardiography allowed a more precise
evaluation of different phases.
CONCLUSIONSThree dimensional
echocardiography and MRI were both useful methods for studying the
physiological volume changes in the left atrium in children. These
methods may be used for further study of the systolic and diastolic
function of the heart.
