Abstract
Anomalous origin of coronary arteries is generally asymptomatic and a rare disease. However, some cases can cause severe life-threatening events such as myocardial ischemia, arrhythmia, and acute myocardial infarction. We describe a case of a single coronary artery arising from the right sinus of Valsalva in a 48-year-old female patient with a complaint of stable angina pectoris and palpitations. Coronary angiography revealed that all three coronary arteries arose from the right sinus. Coronary CT angiography confirmed that there was an anomalous origin of the left coronary artery arising from the right sinus of Valsalva. The patient was managed with conservative treatment.
