NCT00589524
First received: December 21, 2007
Last updated: January 12, 2012
Last verified: January 2012
  Purpose

To compare results of Intravascular Ultrasound (which occurs during cardiac catheterization) with Computed Tomography (CT) scan to detect blockages or narrowing of the arteries that feed the heart. These will be studied in the cardiac transplant population.


Condition Intervention
Heart Transplantation
Device: Computed tomography (CT)

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Comparison of Non-invasive Coronary CT With IVUS for the Detection of Coronary Artery Vasculopathy in a Cardiac Transplant Population

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 ] [ Designated as safety issue: No ]

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
