Abstract

We sought to assess commissural alignment of the balloon-expandable valve on fluoroscopy. Commissural alignment was defined on fluoroscopy in 20 patients according to alignment of the valve commissural posts in the 3-cusp and the cusp-overlap view and correlated with post-transcatheter aortic valve replacement computed tomography. Agreement was strong between computed tomography and fluoroscopy (weighted Cohen's kappa coefficient: 0.88). (Level of Difficulty: Advanced.).

Keywords: aortic valve; computed tomography; valve replacement.
