Summary
Isolated tricuspid valve replacement shows poor outcomes. This surgery had a median survival of only 1.2 years, with high short and long-term mortality rates in patients.
Area of Science:
- Cardiology
- Cardiac Surgery
- Valvular Heart Disease
Background:
- The clinical outcomes of isolated tricuspid valve replacement are not well-defined.
- This procedure is often performed concurrently with other cardiac valve surgeries.
Purpose of the Study:
- To evaluate the short- and long-term clinical outcomes of isolated tricuspid valve replacement.
Main Methods:
- Retrospective study of 15 patients undergoing isolated tricuspid valve replacement between 1984 and 1996.
- Analysis of patient demographics, cause of valve dysfunction, valve characteristics, prosthesis type, and survival data.
Main Results:
- Median survival was 1.2 years.
- Early mortality (<=30 days or before discharge) was 20%, and 3-year mortality was 40%.
- Predictors of mortality included anasarca (short-term), anemia, rheumatic heart disease, prior stroke, and prior mitral valve surgery (long-term).
Conclusions:
- Isolated tricuspid valve replacement is associated with poor short- and long-term clinical outcomes.
- Further research is needed to improve outcomes for this patient population.
