If there are no cardiac malformations or other organ malformations, the pregnancy can continue without major problems. If other abnormalities are present, the pregnancy may need to be terminated. During pregnancy, if the fetal heart vessels are slightly thick, if there are no other malformations, it may be because of the congenital development of the fetus, and the pregnant woman should not worry too much. It is important to do regular checkups, and after delivery, pay attention to the ultrasound examination of the baby’s heart to clarify the baby’s specific situation. If there is a combination of cardiac malformation or malformation of other organs at the time of examination, then there is a need to be vigilant. If the malformation is serious, then the pregnancy needs to be terminated in time under the assessment of the doctor. Pregnant women should do regular checkups during pregnancy and seek medical attention if there is any abnormality.
