ObjectiveThe 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).MethodsThe referral indications and results of FE performed in Iceland 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.ResultsDuring 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.ConclusionsAFCV 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. Key words: fetal echocardiography, indications, congenital heart disease.
