  • HALT, HAM Common After TAVR and SAVR?
    Hypo-attenuating leaflet thickening (HALT) with or without hypo-attenuation affecting motion (HAM) were identified as common findings after transcatheter and surgical aortic valve implantation (TAVI, SAVR) in a recent study published in the European Heart Journal
  • Hypoattenuated Leaflet Thickening-Associated Myocardial Infarction: A . . .
    If there is HALT, TTE may aid in identifying thickened leaflets or reduced motion but CT with contrast is the suggested modality of choice for diagnosis Unless there is concomitant atrial fibrillation or the presence of a heart stent, single anticoagulant medication is now advised for TAVR
  • Hypoattenuated Leaflet Thickening: A Comprehensive Review of . . .
    HALT typically represents subclinical leaflet thrombosis in asymptomatic patients, and as a result it often is detected incidentally However, HALT also may worsen in severity, resulting in leaflet immobility and or valve deterioration
  • Long-Term Follow-Up of Hypoattenuated Leaflet Thickening After . . .
    Early hypoattenuated leaflet thickening (HALT) occurs in at least 10% of all transcatheter aortic valve replacement (TAVR) patients The long-term prognostic impact of HALT is uncertain The aim of this study was to assess the long-term risk of early HALT post-TAVR
  • The Meaning of HALT After TAVR | Cardio Care Today
    Computed tomography (CT) follow-up has identified subclinical leaflet thrombosis (SLT) in the form of HALT or hypoattenuation affecting motion (HAM) following both TAVR and SAVR with some heterogeneity in incidence based on the types of valves used
  • Hypoattenuated leaflet thickening | Radiology Reference Article . . .
    Hypoattenuated leaflet thickening (HALT) is an imaging feature seen on cardiac CT in the setting of subclinical leaflet thrombosis of prosthetic heart valves
  • HYPO-ATTENUATING LEAFLET THICKENING OR THROMBOSIS AND . . . - CHEST
    INTRODUCTION: Hypo-attenuating Leaflet Thickening or Thrombosis (HALT) is well known to be associated with transcatheter aortic valve replacement (TAVR), although it is often subclinical and can only be seen on special CT imaging (1)
  • Hypo-attenuated leaflet thickening in surgically-implanted mitral . . .
    Hypo-attenuated leaflet thickening (HALT) in bioprosthetic aortic valve has been studied, but its equivalent in bioprosthetic mitral valve (bMV) remains uncharacterized We sought to identify the prevalence, hemodynamic characteristics, and significance of anticoagulation therapy in bMV HALT
  • Does Hypoattenuated Leaflet Thickening After TAVR Matter?
    Symptomatic hemodynamic valve deterioration was observed more frequently in patients with (9%) than in those without (2%) HALT In multivariable analysis, HALT was associated with a sixfold increased risk for valve deterioration but not associated with mortality or cerebrovascular events
