I have a question In order to apply to osteopathic cardiology fellowships what are the rules. Of course you need to finish a IM residency, and doing a AOA IM program would be a straight shot, but could you... Go do a good allopathic IM program, get your internship year approved by resolution 42 for hardship. Pay your dues to the AOA for all three years so your a member of the AOA etc. Then apply for osteopathic cards fellowships? Or do they require that you attend a true AOA IM program?
