Key result
Coronary computed tomography angiography (CCTA) and the combination of intravascular ultrasound with bi-plane angiography were compared for characterizing coronary vascular geometry in 28 patients.
Why the study?
Characterization of vascular geometry is fundamental to interpreting coronary artery disease, but the agreement between different imaging modalities needed evaluation.
How does coronary computed tomography angiography (CCTA) compare to the combination of intravascular ultrasound (IVUS) and bi-plane angiography in characterizing coronary arterial geometry in patients with coronary disease?

How does coronary computed tomography angiography (CCTA) compare to the combination of intravascular ultrasound (IVUS) and bi-plane angiography in characterizing coronary arterial geometry in patients with coronary disease?
This study evaluates the agreement between CCTA and IVUS/AX in assessing coronary arterial geometry, which may help characterize coronary artery disease.
CCTA may support non-invasive coronary geometry assessment in small cohorts; leaves open validation against invasive standards before clinical adoption.
The characterization of vascular geometry is a fundamental step towards the correct interpretation of coronary artery disease. In this work, we report a comprehensive comparison of the geometry featured by coronary vessels as obtained from coronary computed tomography angiography (CCTA) and the combination of intravascular ultrasound (IVUS) with bi-plane angiography (AX) modalities. We analyzed 34 vessels from 28 patients with coronary disease, which were deferred to CCTA and IVUS procedures. We discuss agreement and discrepancies between several geometric indexes extracted from vascular geometries. Such an analysis allows us to understand to which extent the coronary vascular geometry can be reliable in the interpretation of geometric risk factors, and as a surrogate to characterize coronary artery disease.
