Different types of valve art
Before starting with echocardiographic evaluation of a valve prosthesis it is necessary to be aware of the different types of valve prostheses. There is a difference in the kind and in the type and diameter. Thus, each manufacturer has its own characteristics. And there is a difference in whether the prosthesis is biologically or mechanically created.
