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.

Polymorphism in C#: Introduction and Types. The word polymorphism can be broken down into two different words, âpolyâ meaning many and âmorphâ meaning forms, and hence the meaning âhaving many formsâ. In C#, or for that matter in any object oriented programming language, polymorphism is used to imply one name with multiple functionality. In polymorphism we declare methods with the same name and different parameters in same class or methods with the same name and same parameters in different classes. Polymorphism has the ability to provide different implementation of methods that are implemented with the same name.
