Coronary access following transcatheter aortic valve replacement (TAVR) can be challenging and is relevant as TAVR expands towards lower-risk younger patients[1]. Prior studies have used post-implantation computed-tomography (CT) scans to suggest several anatomical and device-related factors which can impact coronary access[2–5]. However, the two-dimensional (2D) images and measurements may not fully capture the complex 3D geometry underpinning the challenge of coronary access[4].


In this image, we present a novel CT-based, 3D multi-parametric imaging approach, which was used to evaluate geometrical factors relevant for coronary access.
