The purpose of this paper is to present a case of prosthetic mitral valve thrombosis in a young patient with a history of acute articular rheumatism with bivalvular damage which required prosthetic mitral twin disc and tricuspid annuloplasty that, despite effective anticoagulation treatment, shows a high degree of mitral valve obstruction with severe hemodynamic disturbances that ultimately led to death.
The particularity of the case lies in the development of thrombosis in twin disc prosthesis type, complication that, in the literature, is cited as being more rarely met than the cases of single-disc prosthesis.
