[Management of the prosthetic heart valve patient in clinical practice]. / Surveillance d'un patient porteur d'une prothèse valvulaire.

In use since 1961, valvular prostheses allow the correction of the severe valvular diseases when conservatrice procedures are not possible. Current prostheses have outstanding haemodynamic features. Mechanical prostheses have a supposedly unlimited life span but require anticoagulant treatment. Bioprostheses do not need such treatment but end up to deteriorate and need reoperation. Both can be affected by valve-related complications (thromboembolic events, endocarditis, deterioration, desinsertion...): an ideal prosthesis does not exist yet. All patients with valvular prosthesis require close follow-up, where echocardiography holds preeminent place.
