Objective: Invasive, selective coronary angiography is the gold standard for evaluation of coronary artery disease (CAD) and degree of stenosis. The purpose of this study was to compare 3-dimensional (3D) reconstructed 16-slice multislice computed tomographic (MSCT) angiography and selective coronary angiography in patients before elective coronary artery bypass graft (CABG) procedure. Methods: Sixteen-slice MSCT scans (Philips Mx8000 IDT) were performed in 50 patients (42 male/8 female; mean age, 64.44 8.66 years) scheduled for elective CABG procedure. Scans were retrospectively electrocardiogram-gated 3D reconstructed. The images of the coronary arteries were evaluated for stenosis by 2 independent radiologists. The results were compared with the coronary angiography findings using the American Heart Association segmental classification for coronary arteries. Results: Four patients (8%) were excluded for technical reasons. Thirty-eight patients (82.6%) had 3-vessel disease, 4 (8.7 %) had 2-vessel disease, and 4 (8.7%) had an isolated left anterior descending artery stenosis. In the proximal segments all stenoses >50% (56/56) were detected by MSCT; medial segment sensitivity was 97% (73/75), specificity 90.3%; distal segment sensitivity was 90.7% (59/65), specificity 77%. Conclusion: Accurate quantification of coronary stenosis greater than 50% in the proximal and medial segments is possible with high sensitivity and specificity using the new generation of 16-slice MSCTs. There is still a tendency to overestimate stenosis in the distal segments. MSCT seems to be an excellent diagnostic tool for screening patients with possible CAD.

Objects: We assessed the ability of ST-segment elevation in lead aVR to predict left main and/or 3-vessel disease (LM/3VD) in patients with acute coronary syndromes (ACS). Meterial and Method: 410 patients with ACS, who underwent coronary angiography, were evaluated. Results: 131 (31.9%) patients have been LM/3VD. ST segment elevation > 0.05 mV in leads aVR have been an independent predictor LM/3VD with sensitivity, specificity, positive predictive value PPV) and negative predictive value (NPV) 74.0%, 78.1%, 61.4% and 86.5%, respectively (p<0.001). ST segment elevation > 0.05 mV in leads aVR with ST segment depression in leads V4-V6 have related LM/3VD with sensitivity, specificity, PPV and NPV 44.3%, 92.8%, 74.4% and 75.2%, respectively (p<0.001). ST segment elevation > 0.1 mV in leads aVR have related LM/3VD with sensitivity, specificity, PPV and NPV 51.9%, 87.1%, 65.1% and 79.4%, respectively (p<0.001). Conclusions: ST segment elevation > 0.05 mV in leads aVR have been an independent predictor LM/3VD in patients with ACS. Key words: Acute coronary syndromes, ST-segment elevation, aVR
