Which finding is typical for a diagnosis of gestational trophoblastic disease?

• A. No fetal heart activity
• B. Regular fetal heart rate
• C. Decrease in HCG levels
• D. Normal fetal sizing

Answer: (A)

In the context of gestational trophoblastic disease, the absence of fetal heart activity is a significant finding. This condition encompasses a range of pregnancy-related disorders that arise from abnormal trophoblastic tissue, which is involved in the formation of the placenta. In cases of gestational trophoblastic disease, such as a complete mole, pregnancy may appear to progress initially but is characterized by the development of tissue that resembles placental tissue without the presence of a viable fetus. Typically, there will be no fetal heart activity detected during an ultrasound examination because the abnormal tissue does not support a developing embryo. This absence of a heartbeat is consistent with the fact that these diseases often lead to non-viable pregnancies, differentiating them from normal pregnancies where fetal heart activity is detected. The other mentioned factors, such as having a regular fetal heart rate, a decrease in hCG levels, and normal fetal sizing, are traits associated with a healthy pregnancy rather than gestational trophoblastic disease, which undermines the viability of the fetus and can lead to markedly elevated hCG levels rather than a decrease.
