Fetal tricuspid regurgitation (TR) refers to the backward flow of blood through the tricuspid valve in the fetal heart. It is typically detected during prenatal ultrasound examinations. TR can vary in severity, ranging from mild to severe.
The significance of fetal TR depends on several factors, including the degree of regurgitation, the overall health of the baby, and the presence of any associated abnormalities. A measurement of 241 cm per second in the first scan and 120 cm per second in the second scan suggests a decrease in the severity of the TR.
While it's challenging to provide a definitive prognosis without knowing the full medical history and speaking with a healthcare professional, it's worth noting that in many cases, mild to moderate fetal TR can resolve on its own before or after birth without causing significant health issues. Some infants may require close monitoring or additional tests after birth to assess their heart function.
