title: [Anomalous origin of the left coronary artery from the right sinus of Valsalva with retro-aortic path].
abstract: We present the case of a patient with a dilated cardiomyopathy in which an anomaly in the origin of the left coronary artery, that arose from the right sinus of Valsalva through an own ostium and followed a retro aortic course, was recognized as an angiographic finding. The possible pathways the anomalous artery may follow, and their different clinical significances are reviewed. The angiographic sign of the aortic root, described for the identification of the anomalous origin of circumflex artery, is reviewed and its utility in the case of anomalous left coronary artery is demonstrated. In our case, Thallium-201 didn't show myocardial ischemia with the exercise and that justified, beside the doubtful efficacy of surgery as prophylaxis of sudden death when the anomalous course is retro-aortic, to maintain a conservative attitude.
