Usefulness of multislice computed tomographic coronary angiography to assess in-stent restenosis.
Fifty-one patients (42 men; 60 +/- 12 years of age) who had previous stent implantation underwent multislice computed tomographic coronary angiography. All coronary branches > or = 2.0 mm were independently evaluated by 2 observers and screened for in-stent restenosis (> or = 50%) and occlusion. The consensus reading was compared with the quantitative coronary angiogram. Six of the 74 (8.1%) evaluated stents (3 restenoses and 3 occlusions) were significantly diseased. The sensitivity, specificity, and positive and negative predictive values to identify restenosis were 83.3% (95% confidence interval [CI] 35.9 to 99.6), 98.5% (95% CI 92.1 to 100), 83.3% (95% CI 35.9 to 99.6), and 97.3% (95% CI 92.1 to 100), respectively. One in-stent restenosis remained undetected.
