The impact of left main coronary artery morphology on the distribution of atherosclerotic lesions in its branches

Abstract

Background: Atherosclerotic occlusion of a coronary vessel is the commonest cause of ischaemic heart disease. The distribution of atherosclerotic lesions is not random : Total angiograms: 10.4 mm, 3.8 mm and 86.2 o ; normal group: 10.5 mm, 3.9 mm and 85.7 o , CAD group: 10.2 mm, 3.7 mm and 86.3 o ; 3.7 mm and 91.6 o , 3.8 mm and 79.4 (Folia Morphol 2013; 72, 3: 197-201)

Morphometric analysis of the coronary arteries: a study of the external diameters

“…Data of the external diameter of the LCA obtained in this study were similar to data obtained in the study by Ortale, Meciano Filho, Paccola et al (2005). Additionally, there were similarities not only in the predominance of obstruction in the branches of the LCA but also in the severity (AJAYI, LAZARUS, VANKER et al, 2013). As reported by Marino, Nascimento, Rabelo et al (2012), in cases of acute MI, predominant stenosis was related to the LCA branches in 66.7% of cases, whereas, when we analyzed only the circumflex artery, the rate reached 88.23%.…”

Double Bifurcation Optimization Stent System Technique for Left Main Stenosis

“…The conventional stent is not intended for bifurcations due to huge variation in vessel anatomy (vessel sizes and angulations differences, plaque distribution) and problems with stent deformation and drug coverage disruption . The restenosis and thrombosis rate are higher than in cases of nonbifurcation lesion interventions.…”

Left main coronary artery morphological phenotypes and its hemodynamic properties

“…In 1983, Friedman et al introduced the term ‘geometric risk factors’ for atherosclerosis. Artery length [ 17 ], angle of bifurcation [ 5 ], curvature [ 18 ], and cross-sectional [ 13 ] have all been studied for their role in plaque development, and there is also considerable debate regarding LM length [ 19 , 20 ]. However, hemodynamics is affected by a number of geometric risk factors, rendering it impracticable to precisely evaluate using a solitary morphological parameter.…”
