“…Several studies have demonstrated that age, body weight gender, genetics, and ethnicity play a role in this difference. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] In this study, we preferred using a tabular format to compare our study with earlier studies that employed a similar working methodology ( Table 3). Our study results were comparable to those of the studies conducted in the Iraqi population.…”

IntroductionWith its increasing incidence, coronary artery disease is one of the most common causes of morbidity and mortality especially in the industrialized countries, accounting for more than one-third of total deaths. Cardiovascular diseases are the cause of almost half of the deaths in Turkey. Amongst the European Union countries, Turkey is the fourth in the mortality caused by cardiovascular diseases in men and the first in women. [1,2] Coronary artery diameters are one of the most important factors that affect the technique and outcome of coronary by-pass operations. [3] Coronary arteries arise from the aorta as two branches, the right coronary artery (RCA) and the left main coronary artery (LMCA). After a short distance, the LMCA divides into two, and gives the left anterior descending (LAD) and circumflex artery (Cx) branches. While LAD runs along the anterior interventricular sulcus down towards the apex, Cx artery runs along the atrioventricular groove, giving rise to the left marginal branch. The circumflex then continues around the heart, terminating on its posteroinferior aspect, to supply blood to both the left and right atrium. [4] Lumen diameter of normal human coronary arteries and several factors affecting their lumen diameters have previously been studied in different countries on different populations. [5][6][7][8][9][10] To the best of our knowledge, there is no study with international recognition regarding normal AbstractObjectives: Cardiovascular diseases are the cause of nearly half of deaths in Turkey. Coronary artery diameters affect the procedure and outcome of coronary by-pass operations. The aim of this study was to measure the coronary artery diameters of the individuals with normal coronary artery on angiographic images to assess to provide data for a normal Turkish population and compare the results with studies from other countries.Methods: Seventy-seven male and female individuals between 31-79 years old were used in the study. Diameters of the two coronary arteries and their branches were measured in four segments using the Image J program. Results:The mean diameters of major coronary arteries i.e. LMCA, LAD, Cx and RCA were measured as 4.43±0.76 mm, 3.48±0.53 mm, 3.11±0.67 mm and 3.45±0.50 mm, respectively. Conclusion:This study revealed that the coronary artery lumen diameters of the Turkish population were parallel with the study conducted in the Iraqi population especially. A statistically significant correlation between certain coronary artery diameters were demonstrated also found. The findings of this study will contribute to the diagnosis and the treatment methods for the patients.

“…However, there is little evidence regarding the length, wall thickness, and composition of the tunica media of these arteries (Unlü et al). Furthermore, in most of these studies these parameters are typically measured in one segment (Ballesteros et al, 2011;Barry et al, 2003;Ilayperuma et al;Unlü et al) and some do not define the segment studied (Aroche Aportela et al;Ballesteros & Ramirez, 2008;Barry et al, 2007). The aim of this study was to analyze the morphological and morphometric characteristics of the coronary artery segments that most commonly present occlusion (the AIA, the RCA and The CXA).…”

Morphological Analysis of Major Segments of Coronary Artery Occlusion: Importance in Myocardial Revascularization Surgery

SUMMARY:Revascularization surgery should ensure morphological similarity between the coronary artery and the graft. This is an important factor for its duration and permeability. The aim of this study was to analyze the morphological characteristics and morphometrics of the coronary artery segments with greater occlusion. This was an observational, cross-sectional descriptive study that consisted of two phases. A macroscopic phase in which 11 cadaveric hearts were extracted and coronary dominance and length of the anterior interventricular artery (AIA), the right coronary artery (RCA) and the circumflex artery (CXA) were determined. In the microscopic phase a total of 77 segments of these arteries were obtained and the luminal diameter, wall thickness, and amount of elastic fibers and the presence and size of the atheroma were determined. Right coronary dominance was the most frequent. Total vessel length was 15.65±1.17 cm for the AIA, 12.67±2.02 cm for the RCA and 8.79±2.5 cm for the CXA. Diameters ranged from 2.3 mm in the proximal segments and between 1.1 mm to 1.8 mm in the distal segments. Wall thickness in the proximal segments was between 354 µm and 396 µm and in the distal segments it ranged from 120 µm to 305 µm. The amount of elastic fibers showed that they were muscular arteries. Atheromas were present in 35% in the CXA, and in 32.5% in the AIA and the RCA. The largest ones were found in the proximal segments. This study examined the morphology and morphometry of the segments of the coronary arteries that are more frequently occluded. It provides information on the most significant parameters to be considered for election of the vascular graft in myocardial revascularization surgery.

“…17) The luminal diameter is the most studied and irregular parameter. Most studies only analyzed a single segment, [19][20][21][22][23] whereas others analyzed the segments that are most often occluded 17) or an unspecified segment (Barry et al, 2007 24) ; Ballesteros and Ramirez, 2008 25) ) ( Table 1).…”
