Incidence of major structural cardiac defects in fetuses with increased nuchal translucency and normal karyotype

چکیده
Background Nuchal translucency (NT) is the sonographic appearance of a collection of fluid under the skin behind the fetal neck in the first-trimester of pregnancy. In fetuses with chromosomal abnormalities, cardiac defects and many genetic syndromes NT thickness is increased. The aim of the study was to evaluate the incidence of major cardiac defects in relation to the fetal NT in chromosomally normal fetuses in an unselected Slovenian pregnant population.

INTRODUCTION Numerous papers have proven that an increased nuchal translucency is connected with a raised risk of chromosomal aberrations, but few analyses are related to the further state of fetuses with a normal karyotype. THE AIM OF THE STUDY The aim of the study was to estimate the risk of cardiac defects and other developmental disorders in fetuses with increased nuchal translucency and ...

OBJECTIVE To define the prevalence of major cardiac defects according to nuchal translucency (NT) thickness at the 11 to 13 + 6-week scan in fetuses with normal karyotype. METHODS Specialist fetal echocardiography was carried in 6921 fetuses with normal or presumed normal karyotype at a median gestation of 20 (range 12-35) weeks. The indications for fetal echocardiography were increased NT th...

OBJECTIVE To investigate pregnancy outcome for fetuses with nuchal translucency (NT) ≥3.5 mm but normal karyotype in the Stockholm (Sweden) area. METHODS A retrospective population-based cohort study. From 2006 to 2012, fetal NT was measured in 55123 singleton pregnancies. There were 341 pregnancies with NT thickness ≥3.5 mm; 139 had a normal karyotype, 164 had an abnormal karyotype and 38 we...
