Evaluation of Gold Marker Orientation in the Three-Cusp Coplanar View After Evolut FX Transcatheter Aortic Valve Implantation.

ABSTRACT:

Background

Obtaining commissural alignment in transcatheter aortic valve replacement (TAVR) is important for ensuring coronary access and coronary artery filling, reducing the risk of central leaks, and minimizing leaflet stress. The Evolut FX system has the gold markers placed at the neo-commissures and has demonstrated favorable outcomes. We investigated whether evaluating the orientation of the gold markers in a three-cusp coplanar view (3-CV) after Evolut FX implantation was useful for assessing commissural misalignment (CMA).

Methods

Between April 2023 and December 2024, we included 25 patients who underwent transfemoral TAVR using the Evolut FX for symptomatic severe aortic stenosis. All patients underwent multidetector computed tomography (CT) after TAVR. The native-p
