We report of an previously unpublished combination of partial trisomy
9 and a membranous pulmonary atresia with a large conotruncal ventricu
lar septal defect. The dystrophic female, term newborn presented after
delivery with microcephaly, prominent nose and several other facial a
nd skeletal deformities. The echocardiography and angiography showed a
membranous pulmonary atresia with ventricular septal defect. Chromoso
mal analysis revealed a partial trisomy of the short arm with parts of
the long arm of chromosom 9 and a small part of the long arm of chrom
osom 4. A surgical repair of the heart defect was not performed by the
known high risk of severe mental retardation of partial trisomy 9. Th
e child died at the age of six months.
