Abstract:
Objective To investigate the clinical value and method of fetal tricuspid regurgitation in the first trimester.Methods Fetuses were performed ultrasonography at 11 to 14 gestational weeks,measuring crown rump length,nuchal translucency and acquiring tricuspid waveform.All the fetuses were followed up until 6 months after birth,including prenatal ultrasound examination,maternal serum biochemistry and karyotype test.Results A total of 262 fetuses were performed ultrasonography in the first trimester,the tricuspid waveform were acquired successfully in 249 (95%).Nine cases with tricuspid regurgitation were detected,including 3 cases of trisomy 21,3 cases with complex heart defects,one case with omphalocele,two resulted in intrauterine death and one case of normal chromosome and phenotype.Conclusions Tricuspid waveform is relatively easier to examine and assessment.Tricuspid regurgitation is a useful first-trimester ultrasound marker for the detection of chromosomal abnormalities,cardiac defects,and adverse pregnancy outcome.
