Computed Tomographic Angiography for the Detection of Coronary Artery Stenoses

ByFabian Bamberg, Shawn DeWayne Teague, and Udo Hoffmann

Invasive coronary angiography is currently the standard for

the diagnosis of obstructive coronary artery disease (CAD)

in symptomatic patients. However, about 30-40% of all

invasive coronary angiograms (ICA) in the United States are

performed for diagnostic purposes only.1 This is of concern,

especially as diagnostic ICA poses small but serious

risks (i.e., major vascular complications in approximately

0.40%)2 yielding an overall mortality of 0.13%.3-7 Moreover,

the economic burden with an average charge for patients

hospitalized for diagnostic catheterization of $16,838 in 2000

is considerable.8
