Resumen

BERMUDEZ YERA, Gustavo; CASTILLO GARCIA, Noel  y  ARGUETA CACERES, Nazaret. Late Prosthetic Mitral Valve Obstruction Caused by Thrombus. A Clinical Case Presentation. Medisur [online]. 2011, vol.9, n.5, pp.501-506. ISSN 1727-897X.

Prosthetic valves may present obstructions along their evolutions. The most common causes are thrombosis and the proliferation of scar tissue at long term. The prosthetic valve thrombosis is a complication that can seriously compromise patient’s life. The case of a patient with a late prosthetic valve obstruction caused by thrombus is presented. The patient underwent surgical treatment with a satisfactory outcome. In a surgery performed 21 years before, the patient had undergone a single disc mechanical prosthetic valve replacement. Obstructions had appeared more than once before, but they had been controlled with medical treatment. This obstruction had to be surgically treated because of the magnitude of the disease. Furthermore, the prosthetic mitral valve had to be replaced, as well as the aortic valve that at this point was also compromised.

Palabras clave : heart valve prosthesis; mitral valve; prosthesis failure; thrombosis.
