Similar to all CHDs, TOF isn't excluded. In my previous post, I made mention of risk factors that could lead to these heart disorders and wouldn't want to repeat the same thing in this post. The cause of most Congenital heart diseases are still very unknown. According to research by Hasti Sanandajifar, MD, 25% of TOF patients suffer chromosomal abnormality from fetus, especially the 22q11 deletion syndrome.
Thanks a lot for reading through my post, I really appreciate the time.
