Hypoattenuated Leaflet Thickening and Reduced Leaflet Motion After Transcatheter Tricuspid Valve Replacement

Year: 2025

Type: article

Abstract: 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.
