ABSTRACT
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. METHODS ANDRESULTS:
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).CONCLUSION:
Our result suggests that 64-slice CT coronary angiography has high diagnostic accuracy to detect haemodynamically significant stenosis.
