Abstract: Coronary artery anomalies (CAAs) are present at birth, but are usually asymptomatic and are found during coronary angiography or multi-slice computed tomography (MSCT) detection. The most common coronary anomaly is the separating origin of left anterior descending coronary artery (LAD) and left circumflex artery (LCX) from the left sinus of Valsalva, and this variant is benign. Herein, we present three extremely rare cases of anomalous right coronary artery (RCA) detected incidentally during routine coronary angiography and confirmed by multi-slice computed tomography (MSCT) technique. All the anomalous right coronary artery coursed between the pulmonary artery and aorta. We discuss how to make an accurate diagnosis for appropriate management.
