Principal Investigator: Carey Kimmelstiel, MD

Percutaneous Coronary Intervention (PCI) involves positioning of a stent under Xray guidance to treat coronary arterial stenosis. It then requires intraprocedural assessment of stent positioning and deployment. Standard assessment is done using 2-dimensional angiography possibly augmented with stent enhancement algorithms (e.g. StentViz, GE HealthCare) and/or Intravascular Imaging such IVUS. IVUS brings excellent visualization and clinical information, but it is limited by catheter cost, workflow and time.

Study Requirements

Patients will be recruited for this study prior to standard heart catheterization (PCI). The study will only last duirng the PCI procedure where a 3D acquisition will be performed in addition to standard of care 2D fluoroscopy & angiography images and IVUS imaging. No patient follow up specific to this study will be needed after the procedure, and unless a patient asks to withdraw participation, no additional interaction with the patient is anticipated.
