OBJECTIVE
To analyse
the spectrum of congenital heart malformations, the frequency of
extracardiac malformations, and the proportion of chromosome
aberrations among fetuses sent for necropsy.
MATERIAL
Necropsies
were performed on 815 fetuses
448 induced abortions (55%), 220 spontaneous abortions (27%), and 147 stillbirths (18%)
during a
seven year period (1991-97) in the department of pathology of the
Charité Medical Centre in Berlin. A congenital heart defect was
identified in 129 cases (16%). For all 129 fetuses, karyotyping and an
ultrasound examination had been performed.
RESULTS
Congenital
heart defects were present in 22% of induced abortions (99 cases), 9%
of spontaneous abortions (20 cases), and 7% of stillbirths (10 cases).
The heart malformations were classified into 13 categories. A fetus
with more than one defect was included only in the category of the most
serious defect. The malformations in order of frequency were:
ventricular septal defect (VSD) (28%), atrioventricular septal defect
(AVSD) (16%), hypoplastic left heart (HLH) (16%), double outlet right
ventricle (DORV) (12%), coarctation of the aorta (CoA) (6%),
transposition of the great arteries (TGA) (4%), aortic valve stenosis
(AoVS) (4%), tetralogy of Fallot (TOF) (3%), truncus arteriosus
communis (TAC) (3%), pulmonary valve stenosis/pulmonary valve atresia
(PaVS/PaVA) (3%), tricuspid atresia (TA) (3%), single ventricle (SV)
(1.5%), and atrial septal defect (ASD) (0.5%). The most common
congenital heart defects were VSD, AVSD, HLH, and DORV, which made up
72% of all the cases. In 11 cases the heart defect was isolated (no other cardiovascular or extracardiac malformations present), 85 cases
(66%) were associated with additional cardiac malformations, 85 cases
(66%) were associated with extracardiac malformations, and chromosome
anomalies were detected in 43 cases (33%).
CONCLUSIONS
Fetal
congenital heart malformations are common. These defects are often
associated with other cardiovascular and extracardiac malformations, as
well as with chromosome anomalies. Complex heart defects such as AVSD,
HLH, and DORV are frequent in fetuses, as they often lead to
spontaneous abortion or stillbirth or, after prenatal diagnosis, to
deliberate termination of pregnancy.
