Summary
Isolated tricuspid valve replacement (TVR) is a high-risk procedure with significant early mortality. However, most survivors experience improved quality of life and functional class post-surgery.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Disease
- Medical Device Performance
Context:
- Tricuspid valve disease often requires surgical intervention.
- Isolated tricuspid valve replacement (TVR) is less common than tricuspid annuloplasty.
- Patient populations undergoing TVR often have complex cardiac histories and advanced functional impairment.
Purpose:
- To evaluate the early and late clinical outcomes of isolated tricuspid valve replacement (TVR).
- To assess the safety and efficacy of mechanical and bioprosthetic valves in isolated TVR.
- To analyze survival rates and quality of life improvements following isolated TVR.
Summary:
- This study analyzed 32 isolated tricuspid valve replacements (TVR) in 29 patients (mean age 48, 62% female, 84% NYHA class III/IV) between 1978-1998.
- Hospital mortality was 19%, with 7 late deaths. Actuarial survival was 63% at 5 years and 47% at 10 years.
- Prosthetic dysfunction occurred in 3 cases, requiring reoperation. Most survivors showed improved New York Heart Association (NYHA) functional class.
Impact:
- Isolated TVR is associated with considerable perioperative risk and long-term mortality.
- Despite risks, successful TVR can lead to significant improvements in patients' quality of life and functional capacity.
- Findings highlight the need for careful patient selection and management in isolated TVR procedures.
