3D Stent test to detect stent under-expansion during PCI

Diagnostic Performance of 3DStent to Assess Stent Expansion

Observational CoreAalst BV · NCT06898021

This will test whether 3D Stent can detect stent under-expansion as well as intravascular imaging in people having PCI for coronary artery disease.

What this trial studies

This is an observational, multicenter comparison of the 3DStent imaging technology against intravascular imaging (IVUS) in patients undergoing IVUS-guided percutaneous coronary intervention. Eligible patients present with chronic or acute coronary syndromes and are scheduled for PCI where intravascular imaging will be used. The protocol compares 3DStent measurements of stent expansion to the reference standard intravascular imaging to determine diagnostic agreement. Patients with very long target lesions, high BMI, or unstable hemodynamics are excluded.

Who should consider this trial

Good fit: Adults with chronic or acute coronary syndromes who are scheduled for IVUS-guided PCI and can give informed consent are ideal candidates.

Not a fit: Patients with total stent length requirements over 48 mm, BMI over 35 kg/m2, uncontrolled ventricular tachycardia, cardiogenic shock, or inability to consent are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, 3DStent could offer a faster and less resource-intensive way to identify stent under-expansion and help optimize stent deployment.

How similar studies have performed: 3D angiographic reconstruction approaches have shown promising but variable agreement with intravascular imaging in prior work, so this application is relatively new and requires further validation.
