"Congenital heart diseases are primarily caused by genetic factors and chromosomal abnormalities."
"Exposure to environmental toxins during fetal development is the leading cause of these heart conditions."
"Most congenital heart diseases result from unhealthy lifestyle choices, such as smoking and alcohol consumption."
"The exact cause of congenital heart diseases is unknown, but they can be prevented through vaccination."
