Question
Hello doctor,
I am 25 weeks pregnant, I went to a routine antenatal check-up and the doctor told me that the left ventricular echo was 2.7mm thick. Please ask the doctor if the fetus has a normal left ventricular echo at 25 weeks? Thanks for the advice doctor.

Hello,
With the question “Is it normal for a 25-week fetus to have left ventricular echo? ", the doctor answered as follows:
Negative nodules, also known as bright nodules or thick echoes in the fetal heart, are a common phenomenon in the fetus and most fetuses still develop normally. The bright spot will go away by the end of pregnancy or when the baby is in the neonatal period. If the nodule is bright alone, no other abnormalities are noted, it is benign, if there are fetal abnormalities associated, sometimes additional genetic testing is needed. The cause is still unknown to this day, there are many theories that the myocardium is immature or that the myocardium accumulates more calcium than other areas.
If you are worried, you can go to the hospital to do 1 more fetal echocardiogram in the 3rd trimester of pregnancy. If the results are normal then rest assured and there is no need to worry and follow up.
If you still have questions about the 25-week fetus having left ventricular echo, you can go to a medical facility under Vinmec Health System for early examination and treatment. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
