RAMOS, María Victoria. Surgical aortic valve replacement in middle-aged patients. Mechanical versus biological prosthesis. Rev.Urug.Cardiol. [online]. 2018, vol.33, n.2, pp.75-98. ISSN 0797-0048.  https://doi.org/10.29277/cardio.33.2.5.

Middle-aged patients who require surgical aortic valve replacement constitute a group in wich the decision of the type of prosthesis to implant (biological or mechanical) continues to be discussed. A bibliographic search was carried out in order to determine which of the prostheses benefits this group. When evaluating bioprostheses, the main difficulty lies in structural deterioration, more intense in the younger patient and that may require reintervention due to severe dysfunction. On the other hand, the mechanical prosthesis involve anticoagulation for life, with the risks derived from this treatment. The present article analyzes the most significant evidence to guide the clinical doctor in decision making process.

Palabras clave : Aortic valve-heart valve prosthesis; Bioprosthesis-adverse effects; Patients-middle aged.
