In these, blood is shunted (flows) from the left side of the heart to the right side of the heart, most often due to a structural defect (hole) in the interventricular septum.

    The congenital heart block is a rare disease that affects around 1 child in every 15,000–20,000 births. [3] However, its high mortality (which can be as high as 85% in some severe cases) makes the early diagnosis and intervention very important. [1] CHB can be isolated, where the fetus does not suffer from any other problems, or it can be a ...
