I am scheduled for (Hopefully) Mitral Valve repair surgery in September to repair both the posterior and anterior leaflets. There is some risk that a repair cannot be accomplished and a mechanical valve will be inserted. I am a 45 year old male in excellent physical condition otherwise. Questions:
Polymorphism is an object-oriented programming concept that refers to the ability of a variable, function or object to take on multiple forms. A language that features polymorphism allows developers to program in the general rather than program in the specific.
Polytypism is a type of polymorphism wherein different polymorphs exist in different domains of the same crystal. It has to do with the way that individual layers are stacked within a crystal structure. Polytypism has little geologic consequence, and will thus not be discussed further here.
