controversial. The aim of this study was to investigate the detection rate of major heart anomalies implementing routine use of colour Doppler in fetal heart scanning. We also aimed to identify the main ultrasound finding responsible for the spotting of the heart defect. Methods: From May 2006 to July 2009 colour Doppler was routinely used in all fetal heart examinations in the second and third trimester at Stavanger University Hospital (a secondary level unit). A routine second trimester scan was performed in 6781 women. First, an extended gray scale fetal heart scanning was performed as recommended in ISUOG’s guidelines. Thereafter, colour Doppler was added and three cross-sectional planes through the fetal thorax were assessed; the four-chamber, five-chamber and the three-vessel trachea view. Results: Thirty-nine fetuses examined during the study period had major heart defects, and 26 (67%) of these were prenatally detected. Of these 19/39 (49%) were detected at the routine second trimester scan, three (8%) before the routine scan, four (10%) were detected incidentally later in pregnancy. Thirteen (33%) major heart anomalies were not diagnosed before delivery. The detecting signs were unequal size of the ventricles in four cases, no blood flow across the mitral valve in three, common AV-valve in three, AV-insufficiency in four, overriding vessel in two, parallel vessels in three, one great vessel in ‘‘three vessel view’’ in four, retrograde blood flow in ‘‘three vessel view’’ in two, and abnormal position of the heart in one case. Conclusions: The detection rate in this study is acceptable. Several of the main ultrasound findings are related to blood flow, thus we think the use of colour Doppler is helpful and might be recommended for routine use.
