[What type of heart valve prosthesis after age 70].
The choice of a valve replacement in patients over 70 years of age must take into account various parameters: the type of valve disorder being operated, the probability of post-operative survival in view of the stage of the valve disease and the age of the subject, and the advantages and draws-backs related to the replacements used. In the case of mechanical replacements, the main risks are related to the embolic and hemorrhagic problems inherent in anticoagulant treatment. In the case of biological replacements, the problems are related to the primary degeneration of these valves, which appears to be less frequent the higher the age. In patients over 75 years of age, bioreplacements have more advantages than mechanical valves. In subjects between 70 and 75 years of age, a mechanical valve can be recommended if there is no contraindication to anticoagulant treatment, if there is some other grounds for long-term anticoagulation and if the life expectancy appears to be greater than 10 years. In other situations, a bioreplacement is recommended.
