Abstract
To evaluate the clinical usefulness of
electron beam computed tomography
(EBCT) and its reconstructed 3D imaging
in demonstrating cardiac anatomy in
patients with double-outlet right ventricle
(DORV). In the past 24 months, 43 cases
(boy : girl = 26 : 17; age = 5 days ~
10-year-10-month) with DORV were
analyzed. All EBCT images were taken at
the end-diastolic phase of the cardiac cycle
with intravenous injection of iodinated
contrast medium. 3D reconstructed EBCT
pictures were created with gradient shading
surface rendering. There were sub-aortic
(n=12), sub-pulmonary (n=17).
non-committed (n=13) and double
committed (n=1) subtypes ventricular
septal defect (VSD). In sub-aortic type,
pulmonary annulus located just above the
VSD. In sub-pulmonary type, pulmonary
annulus located just above the VSD. In
non-committed type, the upper margin of
VSD far away from lower margin of the
outlet septum and any great arteries. In
double-committed type, the upper margin
of VSD just supports annulus of both great
arteries. Moreover, by partially removed
the anterior parts of the heart let us can
evaluate the inside cardiac chambers
directly for details on the ventricular outlet,
great arterial root and VSD relationships.
