Formation of Normative Ranges for Multi-Detector Computed Tomography Derived Aortic Annular Measurements

Abstract

Results: 1381 frames (273.4 mm) were analysed identifying 28 fibrous and 175 calcific plaques. Lower SEI was significantly (p < 0.01) associated with larger CP area (80.5% vs 82.2%), higher CP thickness (80.3% vs 82.5%) and lower CP depth (80.8% vs 83.2%). Lower SEC was significantly (p < 0.01) associated with larger FP area (0.84 vs 0.86), higher FP thickness (0.83 vs 0.86), larger FP arc angle (0.84 vs 0.85), larger CP area (0.83 vs 0.86), higher CP thickness (0.83 vs 0.861), larger CP arc angle (0.83 vs 0.86) and lower CP depth (0.84 vs 0.86). Conclusion: OCT-guided assessment demonstrates plaque characteristics significantly impacts on BVS expansion and eccentricity.
