Mechanical heart valve prosthesis superior to biological
A mechanical valve prosthesis has a better survival record than a biological valve prosthesis, according to a large registry study from Sweden’s Karolinska Institutet. The finding, which is published in the European Heart Journal, can be highly significant, since the use of biological valve prostheses has increased in all age groups in recent years.Which type of prosthetic valve is better for relatively young patients undergoing heart surgery for an aortic valve replacement: mechanical or biological? This has been the subject of quite intense discussion amongst doctors and researchers in
