Fetal tricuspid regurgitation at the 11 + 0 to 13 + 6‐week scan: association with chromosomal defects and reproducibility of the method
8 Mar 2006
Abstract excerpt
OBJECTIVE: To determine the reproducibility of diagnosing tricuspid regurgitation (TR) at 11 + 0 to 13 + 6 weeks' gestation, to examine further the relationship between TR and the presence of chromosomal defects and to calculate the likelihood ratios for trisomy 21 and trisomy 18 in fetuses with TR. METHODS: Pulsed wave Doppler of flow across the tricuspid valve was carried out by 12 obstetricians, trained in...
