Brief summary

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.

Interventions

DEVICEComputed 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.

Inclusion criteria

* Heart transplant patients coming to the Cardiac Cath Lab for their yearly angiogram which includes intravascular ultrasound (IVUS)

Exclusion criteria

* Patients with a history of allergic reactions to contrast material Creatine \>1.5 Clinical or hemodynamic instability Those who are unable to consent for enrollment into the study

Design outcomes

Primary

Measure	Time frame
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	within 3 months of cardiac cath with IVUS
