Comparative studies of modern mechanical valve prosthesis (review)

More than 50 years have passed since the first successful heart valve replacement. Since then, many types of mechanical prostheses have been introduced. The prosthesis choice for the replacement of an affected valve is a major concern in valvular surgery. The introduction of a new heart valve prosthesis requires accurate data collection and data processing for a long follow-up period. In present article we sought to compare modern commercial available bileaflet foreign mechanical valve prosthesis for their long follow-up with Russian mechanical valve for aortic and mitral valve replacement.
