Abstract

Objective: We aimed to compare the findings of multi-slice computed tomography (MSCT) coronary angiography and conventional coronary angiography (CCA) in the assessment of coronary artery obstructions and to identify the role of MSCT in the diagnosis of coronary artery pathologies.
Methods: 50 patients (42 males and 8 females, mean age 56±4 years) underwent MSCT followed by CCA within 4 weeks. The patients were on sinus rhythm, could hold their breaths for at least 15 second and had creatinine levels below 1.5 mg/dL. The numbers and rates of obstructions identified in the proximal, middle and distal segments of the coronary arteries with MSCT were compared to those identified with CCA. Sensitivity, specificity, positive, and negative predictive values were calculated.
Results: MSCT had sensitivity, specificity, positive, and negative predictive values for proximal segment obstructions of 95%, 92%,92%, and 95%, respectively; for middle segment obstructions: 95%, 96%, 94%, and 97%, respectively; and for distal segment obstructions: 92%, 96%, 80%, and 98%, respectively.
Conclusion: This study shows us that MSCT is a reliable diagnostic tool in the assessment of coronary arteries, especially in the presence of proximal and middle segment obstructions. Being a non-invasive imaging modality that can be used for screening and diagnosis purposes in symptomatic or non-symptomatic coronary artery disease patients with low-to-moderate risks, MSCT is a candidate technique for more effective and widespread use thanks to the rapid developments in its technology and its continuously increasing success rates.
