HERNANDEZ, Maximiliano et al. Thrombosis on biological prosthetic valve. Case report. Rev.Urug.Cardiol. [online]. 2018, vol.33, n.3, pp.208-216. ISSN 0797-0048.  https://doi.org/10.29277/cardio.33.3.15.

The following article reports a clinical case of a patient with bioprosthetic valvular thrombosis in aortic position. Bioprothesis valve thrombosis is a pathology of low prevalence but it can result in an increase in the rate of stroke as well as in the long term, a factor promoting bioprosthetic degeneration. Currently the diagnosis of the bioprothesis valve thrombosis is made by echocardiography by the finding of an increase in the mean transvalvular gradient greater than 50%, thickening of the cups and / or an abnormal movement of them with a specificity of 93%. Treatment with warfarin has shown to be effective in 83% of patients according to a prospective study, as well as in the case of our patient, with a clear symptomatic improvement as well as a decrease in mean transvalvular gradient after treatment.
