Abstract: Importance Subclinical leaflet thrombosis affects approximately 15% of patients after transcatheter aortic valve replacement (TAVR). The pathophysiology and clinical significance of leaflet thrombosis remain incompletely understood. Defining the optimal management strategy in patients who are… read more here.

Abstract: Subclinical leaflet thrombosis has been increasingly recognized following transcatheter aortic valve replacement (TAVR). Determining the risk factors is vital in preventing clinical leaflet thrombosis and ensuring long‐term value durability. Clinical data have indicated that regional… read more here.

DOI: 10.1016/j.jacc.2020.04.043

Abstract: BACKGROUND Subclinical leaflet thrombosis, characterized by hypoattenuated leaflet thickening (HALT) and reduced leaflet motion observed on 4-dimensional computed tomography (CT), may represent a form of bioprosthetic valve dysfunction. OBJECTIVES The U.S. Food and Drug Administration… read more here.

Abstract: Aims Four-dimensional volume-rendered computed tomography (4DCT) has demonstrated instances of hypo-attenuating leaflet thickening (HALT) with or without hypo-attenuation affecting motion (HAM) after transcatheter and surgical aortic valve implantation (TAVI, SAVR). The temporal pattern of evolution… read more here.

DOI: 10.1161/circ.150.suppl_1.4142998

Abstract: Introduction: Subclinical leaflet thrombosis is an increasingly recognized complication in patients undergoing transcatheter aortic valve replacement (TAVR). Patients with hypoattenuated leaflet thickening (HALT) and reduced leaflet motion (RELM) have a higher incidence of strokes and… read more here.
