Many complications may occur in patients with heart valve replacement. The thrombembolic and bleeding complications are the
most considerable. Choosing between the mechanic and biological valve prosthesis is very important due to many reasons. In case
of mechanical valve prosthesis we can expect life long good function of the prosthesis at the expense of higher thrombembolic and
bleeding complications. The incidence of mechanical valve prosthesis thrombosis is in the range 0.2–1.8 %/patient/year. The treatment
depends on patient´s condition and presence of valve prosthesis obstruction. Reoperation, thrombolysis or anticoagulation therapy is
considered. The bleeding complications are related to the need of life long anticoagulation therapy for patients with mechanical valve
prosthesis. Its frequency is related to the intensity and stability of the anticoagulation therapy, to many factors on the patient´s site and
drug interactions of the warfarin.
