Valvular & structural heart diseaseCohort study
Association of Predicted Surgical Risk With 3-Year Outcomes After Isolated Tricuspid Valve Surgery
- Retrospective cohort study
- U.S. fee-for-service Medicare database
Authors' conclusion
In Medicare beneficiaries undergoing isolated TV surgery, predicted operative mortality was associated with 3-year survival, heart failure readmission, and health care costs. These contemporary real-world data may inform heart team discussions and future trial designs for emerging transcatheter therapies.
Study context
- Population
- Medicare beneficiaries undergoing isolated tricuspid valve (TV) repair or replacement (TVR) from 2018 to 2022, excluding endocarditispatients undergoing isolated TV surgery · TVR 1,285 · TV repair 2,152
- Participants
- 3,437 beneficiaries
- Exposure
- low and intermediate risk groups compared to high risk
Main finding
