Key result
A grading system for valve thrombosis and dysfunction after transcatheter tricuspid valve replacement was developed, though clinical implications remain unclear.
Why the study?
Reduced leaflet motion induced by hypoattenuated leaflet thickening after transcatheter tricuspid valve replacement remains unclassified and its clinical implications are unclear.
Observational
A grading system for valve thrombosis and dysfunction (RLM and HALT) after transcatheter tricuspid valve replacement was developed to correlate with clinical and echocardiographic parameters.
BACKGROUND: Reduced leaflet motion (RLM) induced by hypoattenuated leaflet thickening (HALT) is a known complication after bioprosthetic aortic valve replacement, associated with adverse outcomes. A similar phenomenon has been observed after transcatheter tricuspid valve replacement (TTVR) but remains unclassified. OBJECTIVES: The aim of this study was to introduce a grading system for valve thrombosis and dysfunction after TTVR and describe its clinical and echocardiographic associations. METHODS: severity (none, mild to moderate, and severe) and HALT (0°-4°) were developed. These were correlated with clinical and echocardiographic parameters at 30 days and up to 3 years. RESULTS: and anticoagulation strategy. CONCLUSIONS: remains unclear.

Kempton et al. (2025) conducted an observational in Transcatheter tricuspid valve replacement. Transcatheter tricuspid valve replacement was evaluated on Clinical and echocardiographic parameters. A grading system for valve thrombosis and dysfunction after transcatheter tricuspid valve replacement was developed, though clinical implications remain unclear.
