Single right coronary artery continuing as left circumflex artery and hypoplastic left anterior descending artery: a rare coronary anomaly.
The occurrence of a single coronary artery (SCA) is rare in the absence of other associated anomalies of the heart and is often detected incidentally during coronary angiography. This anomaly is usually benign and various types of SCA have been described. We report a rare type of SCA originating from the right sinus of Valsalva, with the left circumflex artery (LCX) continuing from right coronary artery (RCA) and hypoplastic left anterior descending artery (LAD), which was incidentally found in a 63-year-old female presenting as unstable angina.
