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. | Before starting with echocardiographic evaluation of a valve prosthesis it is necessary to be aware of the different types of valve prostheses.

!Benefits | |||
|Durable | |||
| | |||
*No anticoagulation needed | |||
*Less obstruction of the blood flow | |||
*No Leakage | |||
*Inaudible | |||
*Hemodialysis | |||
*Less risk of infection in the ring or edge flap | |||
*No pannus (tissue ingrowth) | |||
disadvantages | |||
|- | |||
!Anticoagulation needed | |||
| | |||
*Any obstruction of the blood flow | |||
*Leakage (leakage backflow after valve closure, closure backflow flap for closure. | |||
*Audible (ticks). | |||
*Hemodialysis (blood cells break down by colliding with mechanical valve. | |||
*Infection in ring or rim valve (endocarditis). | |||
*Pannus (tissue ingrowth) | |||
|Degeneration is 10-15 years | |||

!NB: For all valve prostheses is indicated in some cases endocarditis prophylaxis. | |||
