Can i drink caffeine such as coffee after mitral valve repair? is decaf coffee ok.

Yes: Caffeine does not effect heart valve function.

Probably: If you are the individual with the valve repair, i would be concerned for a more complex cardiac history. A 21 year old having undergone significant cardiac surgery should carefully discuss all these matters with both surgeon and cardiologist. In general, yes to both caffeinated and decaffeinated.

Shouldn't be any: Problem.

Yes: Coffee is not contraindicated in the majority of patients. If abnormal rhythm issues are present it might be better to avoid caffeine. Moderation is wise.
