Long-Term Survival of Aortic Ball Valve Prosthesis Replacement

A 53-year-old woman had undergone an aortic valve replacement with a Starr-Edwards valve 28 years prior, leading to cardiac failure, mitral stenosis, and mitral regurgitation. Subsequent reoperation replaced both mitral and aortic valves with St. Jude bileaflet mechanical prostheses, revealing a normally functioning Starr-Edwards prosthesis despite lipid infiltration. The replacement was successfully performed, highlighting the long-term durability of aortic ball valve prostheses.

Key Takeaways:

• The patient underwent aortic valve replacement with a Starr-Edwards valve 28 years prior, resulting in cardiac failure, mitral stenosis, and mitral regurgitation. (K. Tayama et al., Circulation Journal, 2004)
• The patient was hospitalized for reoperation, which replaced both mitral and aortic valves with St. Jude bileaflet mechanical prostheses. (K. Tayama et al., Circulation Journal, 2004)
• The explanted Starr-Edwards prosthesis showed no structural abnormality other than lipid infiltration of the silastic ball, indicating its long-term durability. (K. Tayama et al., Circulation Journal, 2004)
• The successful replacement of the Starr-Edwards prosthesis with St. Jude bileaflet mechanical prostheses demonstrates the effective management of heart disease through reoperation. (K. Tayama et al., Circulation Journal, 2004)
• The study highlights the importance of monitoring and addressing complications arising from long-term implantation of aortic valves. (K. Tayama et al., Circulation Journal, 2004)
• The patient's case report demonstrates the necessity of reoperation for addressing the failing Starr-Edwards prosthesis, improving cardiac function and reducing the need for further interventions. (K. Tayama et al., Circulation Journal, 2004)

Statistics:

• The patient underwent reoperation 28 years after the initial aortic valve replacement. (K. Tayama et al., Circulation Journal, 2004)
• The Starr-Edwards valve prosthesis was replaced with St. Jude bileaflet mechanical prostheses during reoperation. (K. Tayama et al., Circulation Journal, 2004)
• The prosthesis replacement was successfully performed, enabling normal functioning of the new valves. (K. Tayama et al., Circulation Journal, 2004)
