Tricuspid regurgitation thresholds reassessed
The proposed framework classified 30% of patients as high or extreme risk, compared with 12% classified as having severe or greater tricuspid regurgitation under established grading schemes.

Clinical Scorecard: Tricuspid regurgitation thresholds reassessed
At a Glance
Category Detail
Condition Tricuspid Regurgitation in Transthyretin Amyloid Cardiomyopathy Key Mechanisms Echocardiographic thresholds for tricuspid regurgitation provide prognostic discrimination. Target Population Adult patients with newly diagnosed transthyretin amyloid cardiomyopathy. Care Setting High-volume tertiary referral centers.
Key Highlights
Study involved 1,124 patients across multiple European countries. Proposed thresholds for tricuspid regurgitation are lower than current guidelines. Significant mortality and heart failure hospitalization rates observed. Framework showed better prognostic discrimination than existing guidelines. Caution advised regarding the use of thresholds for intervention eligibility. Guideline-Based Recommendations
Diagnosis
Utilize standardized transthoracic echocardiography for assessment. Management
Consider the proposed echocardiographic thresholds for risk stratification. Monitoring & Follow-up
Follow patients for mortality and heart failure hospitalization outcomes. Risks
Residual confounding may affect observational study conclusions. Patient & Prescribing Data
Patients with transthyretin amyloid cardiomyopathy.
Thresholds developed for prognostic assessment, not for intervention eligibility.
Clinical Best Practices
Implement standardized core laboratory acquisition and measurement for echocardiographic assessments. Use the proposed thresholds for improved prognostic evaluation. Related Resources & Content
