Fetal Tricuspid Regurgitation in the First Trimester as a Screening Marker for Congenital Heart Defects: Systematic Review and Meta-Analysis.
BACKGROUND Assessment of tricuspid flow has been reported to improve the performance of screening for aneuploidies and congenital heart defects (CHD). However, the performance of tricuspid regurgitation (TR) as a screening marker for CHD in euploid fetuses is yet to be established. The main aim of this meta-analysis was to establish the predictive accuracy of TR for CHD. METHODS MEDLINE, Emba...
متن کاملUltrasound Markers of Chromosomal Anomalies in the First Trimester
Chromosomal anomalies are associated with considerable morbidity and mortality. The protocol for identifying these fetuses had for many years included a single clinical criterion of maternal age. Advances in biochemical screening combined with the excellent display of fetal dysmorphology afforded by technological advances in ultrasound equipment have resulted in a paradigm shift in the diagnosi...
متن کاملScreening for chromosomal anomalies in the first trimester: a report on the first year of prospective screening for chromosomal anomalies in the first trimester in the Czech Republic.
BACKGROUND The increase in maternal age in recent years has intensified the effort to develop early non-invasive methods for screening for trisomy 21 and other chromosomal abnormalities in prenatal diagnosis. In the first trimester of pregnancy, maternal age, fetal nuchal translucency (NT), maternal levels of free beta- human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma pro...
متن کاملPoint-of-care screening for chromosomal anomalies in the first trimester of pregnancy.
Since the serendipitous finding almost 20 years ago of a reduced concentration of maternal serum -fetoprotein (MSAFP) in an index case of a second-trimester pregnancy complicated by trisomy 18 (1 ) and the subsequent confirmation of this finding in other pregnancies complicated by trisomy 21, there has been a gradual improvement in trisomy 21 screening efficiency as better markers have been ide...
متن کاملTricuspid regurgitation in the diagnosis of chromosomal anomalies in the fetus at 11-14 weeks of gestation.
OBJECTIVE To analyse patient data to elucidate the apparent association between an abnormal karyotype and tricuspid regurgitation found during fetal echocardiography at early gestations. SETTING Tertiary referral centre for fetal medicine and cardiology. METHODS Fetuses between 11 and 14 weeks' gestation were selected for detailed echocardiography. Referral reasons were increased nuchal tra...
