Roughly 280,000 people around the world undergo aortic valve replacement surgery every year. Mechanical prostheses are more durable but the patients need to take blood thinning drugs for the rest of their lives. Biological valve prostheses are normally made from cow or pig tissue.

Apart from long-term survival, the group also examined other consequences of the heart valve operations and found that the risk of stroke was similar for both kinds of prosthesis. Patients who had received a biological prosthesis were more likely to need to re-operate the aortic valve, but they also had a lower risk of serious bleeding, a finding that confirms previous studies.

Mechanical Heart Valve Prosthesis Superior to Biological

OBJECTIVES: Concern has been raised regarding the long-term durability of the Mitroflow biological heart valve prosthesis. Our aim was to assess the incidence of structural valve degeneration (SVD) for the Mitroflow bioprosthesis in a nationwide study in Denmark including all patients alive in Denmark who had received a Mitroflow aortic bioprosthesis since 2000.

"Biological valve prostheses have been used more and more in young patients in recent years, partly because these patients don't have to take blood thinners," says Dr Natalie Glaser, PhD student at Karolinska Institutet's Department of Molecular Medicine and Surgery, and a physician at the Karolinska University Hospital's Department of Cardiothoracic Surgery. "Our research shows that mechanical valve prostheses should be the preferred option for young patients."

"We show that patients who had received a mechanical prosthesis had better survival rates than those who had received a biological prosthesis," says Dr Ulrik Sartipy, associate professor at the Department of Molecular Medicine and Surgery at Karolinska Institutet, and cardiac surgeon at Karolinska University Hospital's Department of Cardiothoracic Surgery. "Our results are important since the trend in Sweden and abroad in recent years has been towards a greater use of biological valve prostheses in relatively young patients, which has no backing in clinical therapy guidelines."

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 recent years. In this latest registry study, the researchers examined over 4,500 Swedish patients in the 50 to 69 age-group who had had an aortic valve replacement.

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 , can be highly significant, since the use of biological valve prostheses has increased in all age groups in recent years.

Tissue valves are created from animal donors’ valves or other animal tissue that's strong and flexible. Tissue valves can last 10-20 years, and usually don't require the long-term use of medication. For a young person with a tissue valve replacement, the need for additional surgery or another valve replacement later in life is highly likely.
