We treated successfully using the Ross procedure a 14-year old with a congenitally stenotic bifoliate aortic valve associated with anomalous origin of the right coronary artery. The anomalous artery arose from the same aortic sinus that gave rise to the main stem of the left coronary artery, and reached the right atrioventricular groove by traversing the tissue plane between the aortic root and the subpulmonary infundibulum. Both coronary arteries were reimplanted using a single arterial button.

AbstractIn the normal heart, the right and left coronary arteries arise from the aortic valvar sinuses adjacent to the pulmonary trunk. The right coronary artery then directly enters the right atrioventricular groove, whereas the main stem of the left coronary artery runs a short course before dividing to become the anterior interventricular and circumflex arteries. These arteries can have an anomalous origin from either the aorta or pulmonary trunk; their branches can have various anomalous origins relative to arterial pedicles. Other abnormal situations include myocardial bridging, abnormal communications, solitary coronary arteries, and duplicated arteries. Understanding of these variations is key to determining those anomalous patterns associated with sudden cardiac death. In the most common variant of an anomalous origin from the pulmonary trunk, the main stem of the left coronary artery arises from the sinus of the pulmonary trunk adjacent to the anticipated left coronary arterial aortic sinus. The artery can, however, arise from a pulmonary artery, or the right coronary artery can have an anomalous pulmonary origin. The key feature in the anomalous aortic origin is the potential for squeezing of the artery, produced by either the so-called intramural origin from the aorta, or the passage of the abnormal artery between the aortic root and the subpulmonary infundibulum.

Coronary artery variations are one of the commonest variations observed during clinical procedures. Normally, there are two main coronary arteries, the right coronary artery (RCA), left coronary artery (LCA).Left coronary artery gives two important branches left circumex artery (LCX) and left anterior descending (LAD) arteries. Knowledge about the coronary vessels and its variations are essential to clinicians to prevent untoward injury of vessels during any procedures. To study the morphology and variations of coronar Aim: y arteries by dissection. Materials and Methods: The present study was a cadaveric study which was conducted on 50 hearts obtained from adult human cadavers. Coronary arteries were dissected to see the origin, course and variations. The data was entered in Microsoft excel sheet and expressed in percentage. The Right Results: coronary artery branched out from the right aortic sinus and had an average diameter of 3.5mm. The left coronary artery arouse from left aortic sinus and had an average diameter of 4mm. LMCA divided into two branches in 60 percent, three branches in 30 percent and four branches in 06 percent of the hearts and direct branches from left aortic sinuus in 4 percent hearts.Based on the origin of Posterior descending or interventricular artery, Right dominance was observed in 68 percent, left dominance in 26 percent, and equal dominance in 06 percent of the hearts. Conclusion: Knowledge about the variations of coronary vessels is a prerequisite for clinicians to perform interventions of coronary vessels.

AbstractWe describe a patient with pulmonary atresia and intact ventricular septum in whom the right atrium was divided by a vascular aneurysm located in the right atrioventricular groove. We postulate that the structure represents an aneursymally dilated right coronary artery taking anomalous origin from the pulmonary trunk, with fistulous communication to the right atrium. We discuss the findings relative to concepts of development of the coronary arteries in normal hearts and in pulmonary atresia with an intact ventricular septum.

We have correlated the location of early atheroma with vessel geometry in the major coronary arteries of subjects dying of noncardiovascular causes under 40 yr of age. We analyzed only those vessels affected minimally by very early (fatty) disease. In each of the three major branches, disease was concentrated close to the entrance and diminished with distance downstream. Circumferential distribution of disease was also not random. In the right coronary artery, lesions were concentrated on the inner wall of the major curvature. Immediately downstream of the entrances of both branches of the left coronary artery, the flow-dividing walls were spared. Further downstream in the left anterior, descending branch plaques followed a spiral distribution. We believe these patterns may be determined by local mechanical factors.

Abstract Introduction: Approximately a third of worldwide deaths are caused by ischemic or coronary heart disease, suggesting that greater attention is needed to study the coronary diameter and myocardial vasculature. Material and Methods: In this study, 39 human adult hearts were dissected. The masses of the hearts were measured according to the principle of Scherle and the external diameters of the right coronary artery, the left coronary artery, and the ascending part of the Aorta were measured in millimeters (mm), using a Mitutoyo digital caliper. In the statistical analysis, normal distribution of the variables was assessed using the Kolmogorov-Smirnov test, external diameters were compared using the unpaired Student's t-test, and Pearson's correlation was applied to investigate the correlation of the diameters of the left coronary artery and right coronary artery with the Aorta. Significance was set at P <0.05, and the data were analyzed using GraphPad Prism v.5.00 (GraphPad Software, San Diego, CA). Results: The external diameters were as follows: left coronary artery, 5.55±0.16 mm; right coronary artery, 4.38±0.15 mm (P <0.0001); and Aorta, 22.85±0.80 mm. Thus, it was demonstrated that the external diameter of the left coronary artery is 22% larger than that of the right coronary artery, resulting in a greater blood supply via the left coronary artery and a greater passage of atherosclerotic factors. Conclusions: Despite the importance of the coronary arteries for the heart and the body as a whole, few studies correlated morphometric data and possible clinical implications related to coronary artery disease.

A term female with prenatally diagnosed D-Transposition of the great arteries, large membranous ventricular septal defect with inlet extension, moderate secundum atrial septal defect, and large patent ductus arteriosus (Fig 1) was born by scheduled caesarean section. Transthoracic echocardiogram confirmed the anatomy with both coronary arteries arising from a single sinus with separate ostia. The right coronary artery arose from right posterior facing sinus (Fig 2). The left coronary artery arose anomalously from the same sinus adjacent to the right coronary artery ostium, coursing posterior to the aorta, with brief intramural and interarterial course before bifurcating into the left anterior descending and left circumflex coronary arteries (Figs 3 and 4). As a result of this unique coronary pattern, she underwent unroofing of the intramural left coronary artery noted on opening the aortic root to the coronary ostium. Both coronary buttons were harvested and this large button was then divided into two buttons. The left coronary artery button was implanted with a trapdoor technique, right coronary artery button was implanted, and the remainder of the arterial switch procedure along with LeCompte maneuver was completed uneventfully, with closure of the atrial and ventricular septal defects. The post-operative course was uneventful and the patient was discharged on the seventh post-operative day. At discharge, the patient had normal biventricular systolic function, no residual intracardiac shunt, and robust antegrade flow in the reimplanted coronary arteries. The patient was growing well at the fourth month post-operative visit with normal biventricular function, patent coronaries, and outflow tracts.

Classic anatomical dissection of 150 heart specimens from adults aged 18 − 80 years was performed. Anatomical variations were studied in: (i) the position of the ostium of the left coronary artery; (ii) the angle between the proximal segment of the left coronary artery and the longitudinal axis of the aorta and between the circumflex and the anterior descending branches; (iii) the angle between the anterior descending artery and the diagonal branches, and between the diagonal and circumflex branches in trifurcation of the left coronary artery; (iv) the position of the ostium of the right coronary artery in the right coronary sinus of Valsalva; (v) the angle between the initial part of the right coronary artery and the logitudinal axis of the aorta; and (vi) the position of the initial part of the left coronary artery relative to the coronary groove. Knowledge of and the ability to recognize and identify the variety of sites of origin of coronary arteries, aortocoronary angles and angles of division of the left coronary artery of the human heart may help to overcome potential difficulties in cardiosurgical procedures, such as aortic valve replacement and reinsertion of coronary arteries.

The studies were performed using stereomicroscopic dissection, and light microscopy examination on hearts of healthy and fertile non-human primates ( Macaca fascicularis) of both sexes. The results indicate that the anatomy of the coronary arteries offers points of similarity as well as departure from humans. The blood supply to the hearts was by left (LCA) and right (RCA) coronary arteries. The LCA averaged 1.78 ± 0.29 (SD) mm (range 1.40–2.40 mm) in external diameter at its origin, and 4.34 ± 1.29 (SD) mm (range 1.8–6.5 mm) in length. It usually terminated by dividing into a left anterior descending artery (LAD) and the circumflex branch (CXA). The CXA branch coursed along the left part of the atrioventricular groove and gave off a varying number of branches to the left ventricle and atrium along its course. It averaged 1.14 ± 0.30 (SD) mm (range 0.70–1.70 mm) in external diameter at its origin. The LAD averaged 1.28 ± 0.25 (SD) mm (range 0.90 ± 1.80 mm) in external diameter at its origin. In 73% cases the LAD continued over the apex to course dorsally in the posterior interventricular groove, and gave off a varying number of diagonal and septal branches. The RCA arose from the right aortic sinus and coursed along the right part of the atrioventricular groove and averaged 0.94 ± 0.15 (SD) mm (range 0.70–1.20 mm) in external diameter at its origin. The posterior descending coronary artery (PDCA) arose from the LCA in 55% of the cases, and from the RCA in 45%. Myocardial bridges (MB) were present in 54% of the hearts and over the LCA branches exclusively. The average length of all MB was 5.68 ± 3.31 (SD) mm (range 2.4–11.5 mm). The coronary arteries of Macaca fascicularis are medium sized muscular arteries with well developed tunics intima, media and adventitia, and so resemble human arteries more closely than the dog. Therefore, we suggest this primate species might be a useful model for physiological studies on the coronary circulation.
