My echo says my mitral valve anterior papillary muscle is "prominent." does prominent = hypertrophic? or would they have said hypertrophic if it was?

Hard to say: Tough to tell. Usually whenever i see that reference it is describing mild thickening or simply a visual impression of an entity slightly more obvious than usual. Obviously without seeing the images i can't be certain, but i would wager it is a simple observation that holds little meaning or significance. That's a gentle way of saying if i were you i wouldn't be concerned.
