Anomalous left anterior descending coronary artery arising from the right coronary artery: a case report - Supplementary video

Congenital anomalous coronary artery origins are rare, with a prevalence of 0.24–1.6%. Common

configurations include left circumflex arising from the right coronary (RCA), left main coronary arising

from the right coronary sinus and independent ostia for the left anterior descending (LAD) and left

circumflex. One rare configuration that is not well described is the LAD arising from the RCA. A 68-yearold

patient presented with non-ST elevation myocardial infarction, underwent coronary artery bypass

grafting and was found to have a patent LAD arising from the RCA. In patients presenting with coronary

artery disease and anomalous coronary anatomy, careful preoperative planning and intraoperative

attention to patient anatomy is essential in identifying high-risk coronary anomalies and providing the

correct and optimal treatments for these patients.
