Conditions

Coronary Artery Disease, Percutaneous Coronary Intervention (PCI)

Brief summary

The goal of this observational study is to assess the diagnostic performance of 3D Stent to detect stent under-expansion in patients undergoing percutaneous coronary intervention. The main question it aims to answer is: The study hypothesis is that 3DStent technology will offer a comparable assessment of stent expansion compared to intravascular imaging.

Interventions

DIAGNOSTIC_TEST3DStent

Coronary interventions will be performed according to the standard of care, which includes IVUS guidance. In patients undergoing stent implantation, a 3DStent image acquisition will be done followed by IVUS.

Design outcomes

Primary

MeasureTime frameDescription
Diagnostic performance of 3DStent to detect stent underexpansion with intravascular ultrasound imaging (IVUS) as a reference.Periprocedural timeframeDiagnostic performance will be evaluated in terms of sensitivity and specificity. Intravascular Ultrasound (IVUS)-derived minimal stent area (MSA) ≤ 5.5 mm2 will be used to define stent underexpansion.

Secondary

MeasureTime frameDescription
Clinical utility of 3DStent for guiding stent optimisation with Intravascular Ultrasound (IVUS) as a reference.Periprocedural timeframeClinical utility of 3D stent for guiding stent optimization (i.e. post-dilatation) expressed as a percentage compared with Intravascular Ultrasound (IVUS) as the reference
Feasibility of 3DStent acquisition during the procedurePeriprocedural timeframeFeasibility of 3DStent acquisition during the procedure will be assessed based on the technical success rate.
Agreement on stent expansion between 3DStent and IVUS.Periprocedural timeframeAgreement on stent expansion, expressed as a percentage between 3DStent and IVUS.
Impact of lesion location (vessel and segment) on 3DStent diagnostic accuracy.Periprocedural timeframethe impact of the lesion location (location of the vessel and location of the vessel segment) on the diagnostic accuracy of 3D Stent will be assessed.
Agreement on minimal stent area (MSA) between 3DStent and Intravascular Ultrasound (IVUS).Periprocedural timeframeAgreement on minimal stent area (MSA), expressed in mm², between 3DStent and Intravascular Ultrasound (IVUS).
Impact of calcifications on 3DStent diagnostic accuracy.Periprocedural timeframeImpact of calcifications on 3DStent diagnostic accuracy (measured as mean difference in Minimal Stent Area between 3DStent and IVUS)
Agreement on stent underexpansion and MSA between site and core laboratory.Periprocedural timeframeThe assessment of stent underexpansion and minimal stent area will be compared between the results of the site and the results of a core laboratory.
Radiation exposure associated with 3DStentPeriprocedural timeframeThe dose area product will be measured to assess radiation exposure associated with 3DStent.
Procedural time of the 3DStent workflowPeriprocedural timeframeThe duration of the 3DStent acquisition workflow from the beginning of the centering until the 3DStent reconstruction appears on the screen, will be measured
Agreement on maximal calcium arc as assessed by 3DStent, with IVUS as the reference in cases where 3DStent is acquired pre-PCI.Periprocedural timeframein cases where 3DStent is also acquired before the PCI procedure, there the agreement on maximal calcium arc will be compared between 3DStent and Intravascular Ultrasound (IVUS).
