NCT06499207

Brief Summary

This clinical trial aims to compare non-invasive photon-counting detector computed tomography (PCD-CT) with invasive intravascular imaging (IVI) for post-interventional follow-up in patients with coronary artery disease (CAD). Participants will undergo post-interventional follow-up using both PCD-CT and coronary angiography with IVI. Researchers will test qualitative and quantitative PCD-CT results for non-inferiority to IVI regarding stent evaluation and detection of in-stent restenosis and plaque morphology.

Outcome Measures

Primary Outcomes (2)

  • Quantitative comparison of PCD-CT and IVI in stent evaluation

    Comparison of post-PCI minimal stent area, stent diameter, stent lumen visualization, coronary wall visualization

    Within 1 year

  • Qualitative comparison of PCD-CT and IVI in stent evaluation

    Two experienced radiologists/cardiologists will independently rate image noise and stent artefacts (1 = inadequate; 5 = excellent)

    Within 1 year

Secondary Outcomes (3)

  • Quantitative comparison of PCD-CT and IVI for the evaluation of in-stent restenosis

    Within 1 year

  • Quantitative comparison of PCD-CT and IVI for the evaluation of plaque morphology

    Within 1 year

  • Qualitative comparison of PCD-CT and IVI for the evaluation of in-stent restenosis and plaque morphology

    Within 1 year

Interventions

Patients undergoing follow-up coronary angiography with IVI after percutaneous coronary intervention (PCI) as part of routine clinical practice will additionally receive coronary computed tomography angiography (CCTA) with PCD as part of this study.
