Valve replacement due to mitral stenosis
The biological valve has the advantage of being very similar to the natural (or native) valve and this increases the degree of tolerability. In addition, the biological implant does not require special pharmacological therapy alongside the surgery. The only disadvantage is that it doesn’t last as long over time as it is designed and made with tissues of animal origin that are no longer viable. On the other hand, mechanical valves are more or less indestructible over the years by virtue of the use of materials (like carbon and other special metal alloys) that are particularly hard and resistant to wear. The disadvantage comes from the need to take anticoagulants on a continuous basis to prevent possible clots that could prevent the prosthesis from working properly. The selection of the valve prosthesis in relation to the individual person should be evaluated based on specific parameters, including clinical, like: age, gender, characteristics of the disease and of the valve defect; dimensions of the valve to be replaced; surgical expectation of the patient.
