Can you tell me the difference between coronary and congenital heart disease?

Yes: The former is an acquired condition while the latter is present at birth.

Yes: Congenital heart disease is a cardiac defect present from birth; there are many different variations. Coronary artery disease is stenosis of the arteries of the heart, usually due to arteriosclerosis, although you can rarely have a congenital lesion of a coronary artery- most commonly a coronary comes from the pulmonary artery rather than the aorta- known as an anomalous coronary artery.
