Implication

Cardiac CT may aid redo TAVR planning; leaves open need for outcome trials before routine use.

Key Points

Review the clinical utility of preprocedural cardiac CT in identifying mechanisms of transcatheter heart valve failure and planning redo transcatheter aortic valve replacement.
Synthesized clinical and imaging considerations for redo transcatheter aortic valve replacement (TAV-in-TAV) from a radiologist perspective.
Assessed CT protocols for evaluating structural versus nonstructural valve dysfunction and anatomical alignment.
Cardiac CT differentiates between structural and nonstructural failure modes of the index prosthesis to direct device selection and sizing.
Preprocedural imaging evaluates commissural alignment and coronary proximity to anticipate risks of coronary obstruction and inform leaflet modification.

Population

Patients with index transcatheter heart valve (THV) failure undergoing redo transcatheter aortic valve replacement (TAV-in-TAV)

Intervention

Preprocedural cardiac CT assessment

Preprocedural cardiac CT is a critical tool for planning redo TAVR, offering unique insights into index valve characteristics, coronary alignment, and risks of coronary obstruction.

Jukema et al. (2026) conducted a review in Transcatheter heart valve failure requiring redo TAVR. Preprocedural cardiac CT was evaluated. Preprocedural cardiac CT is an important tool for assessing the mechanism of transcatheter heart valve failure and guiding the sizing and selection of a new valve during redo TAVR.
