A 63-year-old male patient with no significant medical history presented to an outpatient diagnostic center for clinical research purposes. The patient endorsed a healthy lifestyle and denied chest pain, shortness of breath, or any other symptoms. He subsequently underwent cardiovascular computed tomography angiography to evaluate the coronary arteries and was found to have a severely atretic and short ostium of the left main coronary artery (Figure, blue arrowhead). He was also noted to have an anomalous vessel arising from the anterior wall of the aorta, above the sinotubular junction, supplying and creating a native bypass the left coronary artery (Figure, pink arrowhead). High takeoff of the coronary ostium has been previously described in the literature and may result in higher risk of coronary hypoperfusion.1 This anomalous coronary vessel effectively bypasses the critical left main artery and is without evidence of atherosclerotic disease, rendering the individual asymptomatic.
