  • 1

    Transcatheter aortic valve replacement (TAVR) is standard therapy for elderly patients with severe aortic valve stenosis.

  • 2

    Pre-procedural CT is essential for TAVR planning, providing detailed assessments of vascular access and aortic root anatomy.

  • 3

    Reduced contrast media protocols are necessary due to the risk of acute kidney injury in TAVR patients with impaired renal function.

  • 4

    Photon-counting detector CT enhances iodine sensitivity, allowing for reduced contrast agent requirements while maintaining diagnostic quality.

  • 5

    The study implemented a reduced contrast media dose protocol, demonstrating its effectiveness in TAVR planning without compromising image quality.
