Background: The ideal alternative for tricuspid valve replacement (TVR) in patients with severe isolated tricuspid regurgitation remains unvlear. Here, we aimed to retrospectively investigate the outcomes of using bioprosthetic and mechanical valves at the tricuspid position. Methods: Between January 2010 and March 2017, a total of 98 consecutive patients without left-side cardiac disease or history of heart surgery that underwent the first-time TVR at the West China Hospita, China. We retrospectively evaluated patient data, including all-cause death and need for tricuspid valve reoperation as the main end points. Results: A total of 76 patients were enrolled ( mean follow-up, 43.3 months; range 10-87 months. The mean patient age was 45.713.4 years, and 32.9% were male patients. During the follow-up period, 4, 3, 12, and 3 cases of death, reoperation, prosthesis dysfunctions, and prosthesis-related thrombosis were noted respectively. Biological and mechanical valves were used in 56.6% and 43.4% of the patients, respectively. However, there was no significant difference between mechanical and biological valves in terms of echocardiographic date and survival, reoperation, prosthetic valve dysfunction, and thromboembolism rate. Conclusion: TVR is not a very high-risk procedure in patients with isolated tricuspid regurgitation, and the decision for prosthesis implantation in TVR should be made on an individual basis according suitable clinical judgment.
