What does this research mean for the field?

Multimodality and serial imaging are essential for diagnosing and managing complex bioprosthetic valve dysfunction, and the resolution of hypo-attenuated leaflet thickening (HALT) after valve-in-valve TAVR necessitates further evaluation of post-procedural anticoagulation strategies.

Valve-in-valve transcatheter aortic valve replacement for bioprosthetic valve failure complicated by hypo-attenuated leaflet thickening: a case report

Key Points

The resolution of hypo-attenuated leaflet thickening was observed following the valve-in-valve procedure, improving valve function.
Anticoagulation strategies may need to be reevaluated based on outcomes post-procedure, highlighting a gap in current guidelines.

Structured PICO

Population

1 patient with bioprosthetic valve failure complicated by hypo-attenuated leaflet thickening (HALT)

Intervention

Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) and anticoagulation

Outcome

HALT resolutionsurrogate

This case highlights the utility of multimodality imaging in diagnosing complex bioprosthetic valve failure and raises questions regarding optimal anticoagulation strategies for HALT after ViV-TAVR.

Abstract

This case highlights the importance of multimodality and serial imaging in diagnosing and managing complex BVD. The observed HALT resolution raises questions about anticoagulation strategies after ViV-TAVR, especially in the absence of definitive guidelines.
