A Swedish study on 1,712 people found that 92% of those older than 65 who were implanted with St. Jude Medical's Biocor Stented Tissue Valve did not need more heart surgeries after 20 years, compared with 88% of those who underwent a mitral valve operation. The research involved patients who got the stent between 1983 and 2003.
