To determine the diagnostic accuracy of 64-slice multidetector computed tomographic coronary angiography (CTCA) for selecting coronary artery bypass graft surgery (CABG) candidates in consecutive patients with suspicious coronary artery disease, who were referred to CTCA 

There were 1018 patients with a suspicion of coronary artery disease who underwent 64-slice multidetector CTCA between July 2009 and January 2010. Of these patients, we excluded the patients who denied further treatment or who were lost in follow-up. Consequently, a total of 930 patients were included in the analysis. The mean follow-up period was  5.6 months.  We established eligible criteria for coronary artery bypass graft surgery based on American College of Cardiology/American Heart Association practice guidelines: 3-vessel disease, left main coronary disease, and left main coronary artery equivalent disease. To calculate accuracy of CTCA in selecting CABG candidates, presence of angiogrpahical CABG criteria on invasive coronary angiography was considered as true CABG candidates. Absence of angiographical CABG criteria on invasive coronary angiography or no invasive coronary angiography during the follow-up period was considered as true negative. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CTCA were calculated.  

A total of 147 patients underwent invasive coronary angiography. 46 patients had CABG criteria on invasive angiography (3-vessel disease: 25, left main disease: 14, left main coronary artery equivalent: 7). CTCA correctly selected 17 3-vessle disease, 10 left main disease, and 5 left main coronary artery equivalent. The overall sensitivity, specificity, positive predictive value, and negative predictive value of CTCA for the selection of CABG candidates were 75.5%, 97%, 91.4%, 87.5%, respectively.

64-slice multidetector CTCA provided high performance in selecting CABG candidates in patients with suspicious coronary artery disease who were referred to CTCA.

Computed tomographic coronary angiography can be used as an effective method to select coronary artery bypass surgery candidates in patients with suspicious coronary artery disease.
