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 fetal echocardiography, to ascertain the presence or absence of TR in 1557 fetuses at… CONTINUE READING
