Primary Outcome Measures:
  • To determine if Computed Tomography (CT) of the arteries that feed the heart is more sensitive than Intravascular Ultrasound (IVUS) which is performed during cardiac catheterization [ Time Frame: within 3 months of cardiac cath with IVUS ]

Enrollment: 0
Study Start Date: November 2007
Estimated Study Completion Date: November 2009
Estimated Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Computed tomography (CT)
    Computed tomography (CT), as performed by Dual Source Computed Tomography (DSCT)(Siemens Medical Solutions Germany) to be conducted no sooner than 3 days before or after cardiac catheterization, but with 3 months of the cardiac cath.
    Other Name: DSCT Scanner, 4D scanner serial number 60011
