Objective: The aim of the study was to evaluate the
indications and outcomes of fetal echo (FE) and determine
which indication has the highest detection rate for
congenital heart disease (CHD).
Methods: The referral indications and results of FE
performed in lceland during 2003-2007 were reviewed.
Information regarding gestational age at diagnosis, nuchal
translucency, pregnancy outcome, autopsy results and
postnatal diagnosis were obtained from medical records.
Results During the five year period 1187 FE were
performed. Structural heart defect was diagnosed in 73
fetuses. The most common referral indication was family
history of CHD (631;53.2%) which led to diagnosis of 18
heart defects prenatally (2.9%). The second most common
referral indication was increased nuchal translucency (159)
and abnormal cardiac findings were present in 16 cases
(10.1 %). A total of 30 women were referred for FE because
of abnormal four chamber view (AFCV) which resulted in
the diagnosis of 22 (73.3%) major heart defects, either
incompatible with life or requiring immediate intervention
after birth. Other indications led mostly to the diagnoses of
minor defects.
Conclusions: AFCV is the most important predictor for
diagnosis of structural heart defects. 2,5% were referred
for FE due to AFCV which led to diagnosis of 30% of all
heart defects, all of which were major.
