Anomalous origin of the left main coronary artery from the noncoronary sinus of Valsalva

Potential for Using 3D Technology to Image the Origins of the Coronary Arteries

“…39 The left anterior descending coronary artery arising from the posterior coronary sinus is an extremely rare coronary anomaly and has been previously noted in only a few reports. 3,[42][43][44] A single ostium giving rise to both the right coronary artery and left main coronary artery has been reported in a large angiography study in only 0.019% 41,45 and is usually asymptomatic but may present as myocardial ischemia, syncope, or sudden death depending on the course and presence and severity of atherosclerosis. 45 In general, these additional coronary anomalies have risks and associated complications similar to the coronary anomaly they most closely resemble.…”

Selective injection of a left coronary artery arising anomalously from the posterior aortic sinus

“…The overall incidence of coronary anomalies involving origin, distribution, and fistulae formation is 0.2-1.3% [3,, but only one left main coronary artery was found to arise from the posterior aortic sinus in 126,595 patients undergoing coronary angiography at the Cleveland Clinic over a 28-yr period [3]. This anomaly was found incidentally in all cases described either at coronary angiography or by autopsy and was associated with extensive anterior myocardial infarction and death in a 12-yr-old girl [ 5 ] . Our report describes the seventh known case of an anomalous left main coronary artery arising from the posterior sinus of Valsalva and differs from five of six previous studies as it demonstrates selective injection of the anomalous vessel and describes the technique employed.…”

Is Interarterial Course a Requisite for Ischemia in Anomalous Origin of Coronary Arteries?

“…1 Variable presentations of this anomaly have been reported in the literature including sudden death, lifethreatening arrhythmia, exercise-induced myocardial ischemia, premature ventricular contractions, and syncope. [1][2][3][4][5] Case Report…”
