Valve Replacement: Severe valve disorders that cannot be treated by other
methods may need valve replacement. Every patient has to be assessed individually
and a careful decision made regarding replacement. Mitral and Aortic valves are
the commonly affected valves and so the replacements are also common in these
positions.
Variety of valves are available for replacement. However they can be broadly
divided into two categories. Mechanical Valves and Bio-prosthetic (Tissue) valves.
‘Mechanical Vs Bio-prosthetic valves’ is dealt in another section.
Valve Repair: In spite of the tremendous progress made in the design and
structure of mechanical and tissue valves, the ideal valve prosthesis is still far from
reality. No man made valve can match the simplicity and efficiency of natural
human valves. Even in partially defective condition natural valves function better
than the prosthetic ones.
