During the second trimester ultrasound, the heart is checked at 18 to 22 weeks. The doctor examines the structure of the fetal heart and can detect any congenital heart defects. Every year, about 36,000 babies (or 9 out of every 1,000 babies) are born with congenital heart defects. This is the most common type of congenital disorder at birth.
There is no medicine that can treat heart defects in utero. Some minor heart defects cannot be diagnosed until after birth. But detecting these defects during pregnancy helps doctors to decide where your child will be born.

Until your baby is born and takes its first independent breath. The developing fetal circulatory system relies on the umbilical cord to supply oxygenated and nutrient-rich blood. The arteries and veins of the umbilical cord carry oxygen and substances needed by the fetus from you to him. Then deoxygenated blood and waste materials are transferred to you for disposal.</p><p>Just like you, your child has a pulmonary artery (the task of carrying blood from the heart to the lungs) and an aorta (the task of carrying blood from the heart to the whole body). However, between these two, there is another blood vessel called ductus arteriosus. through which the blood flow enters the general blood circulation of the body without the pulmonary circulation. Also, there is a hole between the upper chambers of your baby's heart during the fetal period. called the foramen ovale, whose task during the embryonic period is to create a shortcut to prevent blood flow from the heart to the lungs.</p><p>Related article<a href=)
