A donor valve can be expected to last 10-20 years. Tissue Valve (sometimes called âbioprostheticâ valves) Tissue valves are created from animal donorsâ valves or other animal tissue that's strong and flexible. Tissue valves can last 10-20 years, and usually don't require the long-term use of medication. For a young person with a tissue valve replacement, the need for additional surgery or another valve replacement later in life is highly likely.
Inheritance, encapsulation, abstraction, and polymorphism are four fundamental concepts of object-oriented programming. This article focuses on inheritance. Encapsulation, abstraction, and polymorphism are covered in other articles.Please read Object-oriented programming concepts: Objects and classes and Object-oriented programming concepts: Writing classes if you have not already done so.his article focuses on inheritance.

Abstraction âThe ability to create an abstract representation of a concept in code (as an object named employee is an abstraction of a real employee). Encapsulation âEncapsulation is all about the separation between implementation and interface.In other words, when you encapsulate an object, you make its code and data internal and no longer accessible to the outside except through a well-defined interface. This is also called data hiding.bstraction âThe ability to create an abstract representation of a concept in code (as an object named employee is an abstraction of a real employee).
