immediate respiratory distress, cyanosis, and
hypoxemia. Congenital heart malformation was
suspected Chest roentgenogram revealed
dextrocardia, mild cardiomegalie, increased
pulmonary venous marking, and left aortic arch
(the major axis of the heart oriented from
left shoulder to right hip, with the
morphologic left atrium located to the left of
the morphologic right atrium), obstructed
infradiaphragmatic TAPVR to the portal
vein/inferior vena cava, large secundum atrial
septal defect, and patent ductus arteriousus.
All the pulmonary veins coalesced behind the
right atrium into a common pulmonary venous
confluence, which drained to the portal
system. Splenic tissue in the left upper
quadrant suggesting abdominal situs solitus.
After surgery, secondary supraventricular
tachycardia At 8 month weight: 15th, length:

Pregnancy and
delivery normal, at birth weight 3485 g, APGAR
score 7-9-10. Dysmorphic bilateral optic disc
coloboma, small chin, broad mouth, large
tongue, angulated ears, pronounced nuchal skin
folds and bilateral partial syndactyly of
second and third toes, patent ductus
arteriousus, mildly reduced myocardial
contractility. Brief myoclonic spasms in lower
extremities observed 1month after birth.
Shortly after this, generalized tonic-clonic
seizures. The electroencephalogram was normal
and computed tomography showed no radiological
abnormalities of the brain and skull.
Swallowing was difficult and there was
hypertonia of lips and cheeks. At 15m received
a percutaneous endoscopic gastrostomy. Weight
and head circumference are within normal
limits, whereas height is more than 3 SD above
normal. She still often falls to one side when
sitting, she can stand only when held and
helped, does not yet walk and has mild flexion
contractures of her knee joints |
