“…We observed 1 such case in the present study. The left coronary from the right posterior sinus was also rare [20] and was observed in one heart in the present study. The left coronary artery when originating from the right posterior sinus runs horizontally between the aortic root and left atrium towards left coronary sulcus.…”

In the light of increased incidence of coronary arterial diseases, knowledge of the variations in the number and location of coronary ostia is essential in the planning of various interventional and surgical procedures on the coronary arteries as well as aortic valve replacements. Aim: To investigate the variations in the origin, number, size and location of coronary ostia in relation to aortic leaflets. Methods: Eighty adult human cadaveric hearts with great vessels in situ were studied for coronary ostia. Results: 78 hearts had tricuspid aortic valve and two hearts had bicuspid aortic valve. Anomalous origins of right coronary artery from the left posterior aortic sinus in one heart and the left coronary artery from the noncoronary sinus in another heart were noted. Both right and left coronary arteries arose from the anterior aortic sinus in two hearts with bicuspid aortic valve. Single right coronary ostium was seen in 63 hearts (78.75%), two right coronary ostia were found in 14 hearts (17.5%), three right coronary ostia were found in two hearts (2.5%), and four were found in one heart(1.25%). The left coronary ostium was single in all hearts. The mean diameter of right coronary ostium (RCO) was 3.17±0.87 mm and of the left coronary ostium (LCO) was 4.1±0.83 mm. The relation of the right and left coronary ostia to the sinu-tubular junction, to the bottom of the related sinus and to the commissures was also analyzed in detail. Conclusion: This study provides data on normal coronary ostial morphometry and topography and there were significant differences in the number of right coronary ostia than of the left coronary ostium. The observed large variations of coronary ostial position in relation to the sinu-tubular junction and to the bottom of the aortic sinus emphasize the importance of considering such anatomic variations in the development of treatments for coronary artery occlusion.

“…The incidence was the highest for the separate origin of the left anterior Ectopic coronary origin from the opposite aortic sinus (1.9%) and single coronary artery (3.88%) were described but they are rare [2]. The literature is poor of cases describing an anomalous origin of the LCA from the non-coronary sinus of Valsalva [3][4][5][6]. Two-dimensional echocardiography, computed tomography angiography and magnetic resonance are the most important diagnostic instruments for the evaluation of the coronary anomalies [7].…”

A 73-year-old man presented to our department for ischemic alterations appeared during a stress electrocardiogram. The diagnostic process including coronary angiography, cardiac computed tomography and echocardiogram revealed an anomalous origin of the left main coronary artery from the commissural region between the left and the non-coronary Valsalva sinus associated with non-obstructive accessory mitral valve tissue. Although these malformations are relatively common the association is not described in literature to date.

“…4,5 Specific triggers, such as increasing demand for oxygen during exercise, and decreased coronary blood flow due to tachycardia as well as a short diastolic phase, may also contribute to a massive myocardial infarction. 6 The order of the most common etiologies of SCD in adolescents is HCM, anomalous coronary artery, myocarditis, ruptured aortic aneurysm, and arrhythmogenic right ventricular dysplasia. 5 Although the prevalence of SCD among athletes is quite low, estimated to be between 1/10,000 and 1/300,000 athletes, 7,8 SCD has a large impact and receives much attention when an otherwise fit young person dies suddenly.…”

Summary: Congenital anomalies of the coronary arteries are relatively uncommon conditions and have been associated with sudden cardiac death (SCD) in children. Although anomalous coronary artery distribution is widely reported in the literature, no articles to date address the origin of both the right (RCA) and left coronary arteries (LCA) from the posterior (noncoronary) sinus of Valsalva. This is a report of a 16-yearold black male in good health, who collapsed and was unable to be resuscitated after physical exertion while playing basketball. In this patient, postmortem evaluation revealed the LCA and RCA originating exclusively from the posterior (noncoronary) sinus with acute angle takeoff of the LCA which likely lead to ischemia, causing SCD. We discuss the incidence of coronary artery anomalies and the proposed mechanisms that led to SCD in these patients.
