OBJECTIVE The objective of our study was to evaluate the diagnostic accuracy of 64-slice computed tomography coronary angiography to detect haemodynamically significant stenosis (>50% luminal narrowing) in comparison to invasive coronary angiography and further analyze the result accounting for heart rate, coronary calcification and location of lesion in the coronary tree. RESULTS Forty patients (39 male, 1 female; mean age 50.9 years) underwent both CT coronary angiography and invasive coronary angiography with in a gap of one day. All vessels were included in the study and no patient was excluded due to high heart rate. On per-segment based analysis with invasive coronary angiography as the gold standard, CT coronary angiography correctly identified 62 out of 78 significant stenoses with an overall sensitivity of 79.5% (62 of 78), specificity of 98.5% (532 of 540), positive predictive value of 88.6% (62 of 70) and negative predictive value of 97.1% (532 of 548). CONCLUSIONS Our result suggests that 64-slice CT coronary angiography has high diagnostic accuracy to detect haemodynamically significant stenosis.
