Abstrakt: Objectives: Angiography by selective catheterization is the standard method for coronary artery imaging but carries a risk of rare, but serious complications. We investigated whether 16-slice multidetector spiral computed tomography (MDCT) could substitute for selective angiography for evaluation of coronary artery disease in surgically revascularized patients.
Design: In a setting closely resembling routine clinical practice, 45 patients who had been operated with coronary artery bypass grafting 508-1135 (mean 811) days before were examined with MDCT and conventional selective angiography on the same day. The interpreters were blinded to the results of the parallel imaging modality.
Results: Significant pathology (stenosis >/=50% or occlusion) in the larger coronary artery segments was detected by MDCT with a sensitivity of 70-98% (mean 87%) and a specificity of 0-37% (mean 21%). MDCT failed to identify three of ten left main stem stenoses.
Conclusion: Sixteen-slice MDCT cannot routinely replace selective angiography for evaluation of coronary artery disease.
