Abstract

Background: The common and potentially fatal disorder known as coronary artery disease (CAD) is characterised by turbulent and sluggish blood flow at the coronary artery bifurcation site, particularly at broader angles. Curved multiplanar reformat (CMPR) and 3D volume rendering (3D VR) techniques could help in prediction of CAD. Objective: The aim of the current study was to evaluate of the capability of Multi-detector CT (MDCT) coronary angiography to quantify coronary bifurcation angles for early preventative treatment or preprocedural planning for coronary intervention. Patients and methods: Using a 128-detectors scanner, 60 patients with typical or atypical chest discomfort or failed catheterization received MDCT coronary angiography to characterise coronary anatomy. Coronary bifurcation angles were calculated using specialised software and post-processing methods for correlation with CAD severity. Results: Compared to the 3D VR approach, the CMPR technique revealed wider values of coronary bifurcation angles. However, Bland-Altman plots showed that both methods may be alternatively used. Because a wider angle was linked to a greater degree of stenosis, LAD-LCX angle differed significantly between individuals with significant and nonsignificant CAD. Conclusion: Measurements of various coronary bifurcation angles, particularly the LAD-LCX angle, which is thought to be a predictor for CAD, can be made using MDCT coronary angiographic examination with CMPR and 3D VR methods. More plaques are likely to form when the angle is wider.
