Fetal tricuspid valve mild regurgitation pregnant women what's going on

The prenatal examination indicates that most of the fetuses with mild tricuspid regurgitation belong to physiological regurgitation, without special pathological significance, generally due to the sensitivity of cardiac ultrasound. If the tricuspid regurgitation velocity is less than 0.8/s, it may also be caused by fetal pulmonary stenosis. At present, it is necessary to strengthen observation and recheck one month later.
