64-Slice Multi-Detector Computed Tomography (MDCT) Coronary Angiography has a High Diagnostic Accuracy in Assessing Graft Patency, Stenosis and Distal Runoff

Of the 296 segments negative for stenoses on ICA, 288 (97.3%) were correctly identified by MDCTA. Segmentby-segment and patient-by-patient analyses revealed a sensitivity, specificity, positive predictive value and negative predictive value of 77.8%; 98.6%; 87.5%; 97.3% and 100.0%, 64.3%; 79.2%; 100.0%, respectively. Nine patients represented with a cardiac event (CE) during follow-up: seven had ≥1 stenosis on initial MDCTA and two had a non-interpretable MDCTA. Patients with a negative MDCTA, had no CE during follow-up. Conclusion: MDCTA excludes significant coronary disease and may be a useful non-invasive screening tool in patients with chest pain with a non-diagnostic stress test. doi:10.1016/j.hlc.2007.06.094
