Coronary Artery and Coronary Artery Bypass Graft Imaging Using a Specialized Catheter and Computed Tomography
Withdrawn before enrolling · Phase 1
Conditions studied: Coronary Artery Disease
In brief
The present study relates to a new approach to coronary artery and coronary artery by-pass graft imaging, and more particularly to computed tomographic angiography following an aortic root injection of a low amount of contrast (up to 30 cc) via a percutaneously placed catheter (Vanguard DX, Medrad Inc.) positioned in the aortic root. The objective of the study is to show the feasibility of Coronary artery CTA using aortic root injection of contrast compared to the standard invasive cardiac catheterization.
