Stereotaxis Computed Tomography (CT) Co-Registration Study

This study has been terminated.
(Study terminated due to lack of enrollment.)

The Stereotaxis Niobe® II Magnetic Navigation System (MNS) is designed to direct and digitally control catheter and guidewire based therapeutic and diagnostic devices along complex trajectories within the heart and coronary vasculature.

Navigation using vectors acquired from the CT Co-registration feature of Navigant™ provides clinical benefits for percutaneous coronary intervention (PCI) by decreasing the amount of contrast used during complex PCI procedures.

Condition Intervention
Coronary Artery Disease
Procedure: Percutaneous coronary intervention

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Randomized Feasibility Study Comparing the Clinical Utility of the Stereotaxis Navigant™ Computed Tomography Angiography Importation and Co- Registration Feature, the NaviView™ Assisted Navigation Feature, and Standard Angiography

Primary Outcome Measures:
  • The primary endpoint is to compare and evaluate the total contrast use between Groups A, B and C . [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • The secondary endpoint is to compare and evaluate the following data points between Groups A, B and C: fluoroscopy time, procedure time, crossing time, procedural contrast use, adverse events (AEs): e.g. clinically significant perforations [ Time Frame: 6 months ]

Enrollment: 4
Study Start Date: October 2009
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Group A-CT Coregistration
5 subjects with CT co-registration in a magnetically navigated PCI (Group A)
Procedure: Percutaneous coronary intervention
non surgical procedure to open blocked coronary arteries
Active Comparator: Group B-Angiographic
5 subjects with angiographic co-registration in a magnetically navigated PCI (Group B)
Procedure: Percutaneous coronary intervention
non surgical procedure to open blocked coronary arteries
Active Comparator: Group C-Standard Angiography
5 subjects with standard angiography in a conventional PCI (Group C)
Procedure: Percutaneous coronary intervention
non surgical procedure to open blocked coronary arteries


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must be between 18-80 years of age
  • Willing and able to provide prior written informed consent
  • Patients present with a single bifurcated lesion or single non-CTO complex lesion requiring PCI.
  • Able to be safely exposed to magnetic fields, such as magnetic resonance imaging (MRI)
  • CT angiography performed prior to cardiac catheterization (must be performed >48 hours prior to procedure to limit peri-procedural contrast use, but <12 months prior to the procedure)

Exclusion Criteria:

  • Patients with a creatinine greater than 2.0 mg/dL
  • Exclude patients whom in the Investigator's opinion, are hemodynamically unstable on the day of the procedure.
  • Untreatable allergy to contrast media
  • Patients who have undergone CT angiography within 48 hours of index PCI procedure
  • Patients with chronic total occlusions (CTOs) requiring intervention.
  • Patients requiring treatment for lesions other than the single bifurcated or single non-CTO complex lesion.
