“…The mean of RCA ostium diameter in the present study was 3.43±0.63 in male, 3.34±0.59 in female and 3.4±0.61 mm in all cadaveric hearts and that of LCA was 4.46±0.68 in male, 4.38±0.74 in female, and 4.43±0.69 mm in all cadaveric hearts with no sex difference but there was a significant difference ( P <0.001) between the ostial diameter of RCA compared to that of LCA. In consistence with the results of this study, the mean of the internal diameter of RCA ostia varied from 3.17 mm to 3.9 mm and that of LCA measured from 4.1 mm to 4.96 mm in different researchers [ 3 8 13 16 17 19 ]. However, in contrary to the findings of this investigation, the mean of RCA ostia diameter was 2.5±1.0 mm and 2.38±1.33 mm and that of LCA ostia was 2.8±1.0 and 3.17±0.39 mm, respectively [ 18 ].…”

“…In this study, the site of the coronary ostia was observed below STJ in 80% of RCA, in 73.3% of LCA and in 85.7% of TCA with no significant sex difference. Similarly, a higher incidence of coronary ostia below STJ was recorded than that at or above STJ levels; in 90% of RCA and 73.3% of LCA ostia [ 10 ]; in 65% of RCA and 52.5% of LCA [ 13 ]; in 78% of RCA and 68% of LCA ostia [ 8 ]; in 63% of RCA and 44% of LCA [ 15 ]; in 73.3% for all [ 9 ]; in 78% of RCA and 58% of LCA [ 16 ]; in 90% of RCA and 80% of LCA ostia [ 2 ]; in 75% of RCA and 85% of LCA [ 17 ]; in 60% of RCA and 42% of LCA [ 3 ]; and below STJ in 89.5% of RCA and 80% of LCA and in 6.7% of RCA and 15.2% of LCA at the level of STJ and in 3.8% of RCA and 4.8% of LCA above STJ [ 2 ].…”

This study was carried out to investigate the morphometric parameters and variations of coronary ostia in the hearts of adult human cadavers and coronary angiographs. The hearts of 60 adult human cadavers and 400 coronary angiographs were used in this study. The root of the aorta was carefully dissected to clear aortic sinuses, coronary ostia, and sinutubular junction (STJ). Number, locations, internal diameter distance between coronary ostia and their corresponding STJ, sinus bottom, and valve commissures were investigated. The anterior aortic sinus (AAS) revealed a single ostium for right coronary artery (RCA) in 77.5% of male and 80% of female hearts. This ostium gave a common origin for RCA and third coronary artery (TCA) in 15% of male and 20% of female hearts. However, two separate ostia for RCA and TCA origin were seen in 20% of male and 15% of female hearts. Moreover, three ostia were seen in one male and one female hearts within AAS. Meanwhile, the left posterior aortic sinus showed a single ostium for left coronary artery (LCA) in 97.5% of male and 95% of female hearts and two ostia in one male and one female hearts. The ostia were commonly seen below STJ and less commonly were observed above STJ. The distance between the bottom of aortic sinus and LCA ostium was longer than that of RCA. The internal diameter of RCA ostium was significantly (P<0.05) narrower than that of LCA but with no significant sex difference. Moreover, anomalous of coronary ostia was observed in seven out 400 angiographs and in two cadaveric hearts. Knowledge the morphometric parameters and anatomical variations of coronary ostia helps the cardiac surgeons to overcome the possible difficulties that could occur during surgical and radiological coronary interventions.

“…We also found that larger atheromas had a thicker intima. Moreno et al (2002) and López-Mínguez et al (2006) mention that atherosclerotic plaque frequently forms in the most proximal segments and that changes such as rupture of the internal elastic membrane and atrophy of the tunica media with a decrease in thickness and the amount of elastic fibers, occur in the wall. These changes coincide with what we found during microscopic analysis.…”

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.

“…Goldstein et al (5) reported that 89% of ACD is on the right side and 11% on the left side. López Mínguez et al (6) reported that most cases of ACD are in the RCA, because the RCA has fewer smooth muscle cells and matrix type-1 collagen fibrils than the left coronary artery sinotubular junction.…”
