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. Their prevalence is less than 1.3% based published series 1-4. The most common coronary anomaly is separate origination of the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) from left sinus of Valsalva. The second most common anomaly is origination of the LCX artery from the right coronary artery (RCA) or right sinus of Valsalva. Herein, we present two cases that the anomalous RCA arises from the distal of left circumflex coronary artery. It is belonging to single coronary artery (SCA). The case is rare. we bring forth these cases in an attempt to highlight their significance, and make cardiologist understood what important the anomalies are.
