Brief Summary

Intracoronary optical coherence tomography (OCT) imaging allows for high-resolution characterization of coronary lesions. Difficulties in matching cross-sectional OCT-images with angiographic lesion localization, however, may limit its clinical utilization. The investigators sought to prospectively assess the impact of a novel system of real-time OCT-coregistration with angiography (ACR) compared to OCT alone and to the clinical standard proceeding (angiographic guided-PCI) all used for coronary lesion evaluation before percutaneous coronary interventions (PCI). The investigators hypothesize that the use of ACR will lead to less incidence of insufficient covered coronary lesions (geographical mismatch) and/or a less rate of edge dissections after PCI (combined primary study endpoint)

Outcome Measures

Primary Outcomes (1)

  • Incidence of a combined endpoint based on "major edge dissections" (I) AND/OR "geographical mismatch" (II) [%]

    Analysis of primary endpoint will be assessed by evaluation of proximal and/or distal stent end. I) Major edge dissection (MED): Major: ≥60 degrees of the circumference of the vessel at site of dissection and/or ≥3 mm in length II) Geographical mismatch (GM): Untreated plaque with a minimal lumen area \<4,5mm2 within 5mm of the reference segment. In the postPCI-OCT analysis it is considered as no geographical mismatch, if: 1. the segment of the lesion is fully covered AND 2. the stent protrudes maximal 5mm beyond the predetermined landing zone. If one of these criteria is not fulfilled, it is considered as geographical mismatch

    Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours

Secondary Outcomes (18)

  • Incidence of "major edge dissections" [%]

    Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours

  • Incidence of "all edge dissections" (major (I) and minor (II)) [%]

    Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours

  • Incidence of "geographical mismatch" [%]

    Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours

  • Stent expansion [%]

    Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours

  • Inacceptable stent expansion [%]

    Time of PCI Procedure - participants will be followed for the duration of hospital stay, an expected average of 24 hours

  • +13 more secondary outcomes
