Heart valve replacement therapy is performed successfully for more than 40 years. The ideal valvular prosthesis is yet to be found. Many acceptable substitutes exist today for the replacement of diseased human heart valves. Two major groups of prosthetic valves are currently available: mechanical and biological valves. The major differences between these two groups are in terms of durability and risk of thromboembolism. Mechanical valves are more durable, biological valves have lower risk of thromboembolism. Mechanical heart valves are classified into three major groups: caged-ball, monoleaflet disc, bileaflet valves. Stented heterografts, stentless heterografts, homografts and pulmory autografts are currently used biological valves. The choice of the heart valve prosthesis is a serous situation. The choice of the heart valve prosthesis must be a joint decision by the patient, Cardiologist and Surgeon after a full and complete discussion of the risks and benefits for the individual patient. The results of valve surgery with regard to short and long-term results are dependent on especially patient-related factors and type of prosthesis and type of surgery as well.Keywords: Prosthesis, heart valves, valve surgeryTurkiye Klinikleri J Int Med Sci 2006, 2(15):43-50
