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.
