Association between three-dimensional vessel geometry and the presence of atherosclerotic plaques in the left anterior descending coronary artery of high-risk patients

Coronary arterial geometry: A comprehensive comparison of two imaging modalities

“…Recently, arterial tortuosity, manually acquired, was proposed to be a protective factor 30 . The result reported in the above study would coincide with that of Reference 31. That is, large values of mean curvature in the distal regions of LAD arteries were found to be associated with less prevalence of coronary artery disease.…”

“…Results reported in the present study indicate that several geometric features present significant differences between CCTA and IVUS models of the very same artery. Many of these features were previously found to be associated with lesion prevalence, [30][31][32] or with the RCA shape, which in turn is related to disease. 32 Furthermore, in Reference 10, it was shown evidence of potential heritability of arterial geometry, and, according to the results shown here, some of the features identified as heritable markers (for the LAD and LCX) present significant differences when quantified from CCTA or IVUS models, specifically, f r,ξ κ , κ T , T κ }.…”

Extraction of Coronary Atherosclerotic Plaques From Computed Tomography Imaging: A Review of Recent Methods

“…For example, radius gradient of the plaque, which reflects longitudinal lesion asymmetry, has been proven to be associated with the location of plaque rupture and consequent clinical events ( 95 ). The curvature and tortuosity of coronary arteries might be related to the development of atherosclerosis and plaque size ( 96 , 97 ). These secondary parameters and their clinical indication need further investigation.…”

Tortuosidade das Artérias Coronárias como um Novo Fenótipo para Isquemia sem Doença Arterial Coronariana

“…27 Estudos sobre fluidodinâmica computacional chamam a atenção à importância das medidas realizadas por equações matemáticas complexas que explicariam melhor como ocorre a distribuição da pressão ao longo da circulação e do fluxo coronários. [28][29][30][31][32][33][34] Limitações Nosso estudo tem algumas limitações. A primeira limitação é o pequeno tamanho amostral e sua natureza retrospectiva (Figura 4).…”
