In brief: Can be either

The majority of mitral stenosis is a result of a previous strep infection which cause rheumatic fever. This begins a slowly progressive scarring of heart valves.
The aortic and mitral valves most commonly. However there can be congenital mitral stenosis when the mitral valve may not form big enough during fetal development.
