Anomalous Origin of the Right Coronary Artery from the Left Coronary
Sinus in a child : case report
Abstract
A 11 year-old boy with no relevant past cardiac history presented with
complain of chest pain last 10 days . Electrocardiography showed sinus
rhythm incomplete RBBB with no ST –T changes at rest ,Subsequent echo
revealed abnormal origin of RCA with normal systolic and diastolic
biventricular functions, CT- Coronary angiography finally confirmed the
diagnosis and showed abnormal origin of right coronary artery that arose
from the left coronary sinus- that has been associated with angina,
myocardial infarction, and sudden cardiac death. The incidence of
coronary anomalies in patients undergoing coronary angiography varies
from 0.64% to 1.3%. Many of these anomalies are clinically benign;
however, others are associated with serious morbidity6. We describe the
case of a patient in whom evaluation of chest pain revealed an anomalous
right coronary artery arising from the left coronary sinus. We discuss
the clinical importance of this anomaly and review the literature
concerning current views and therapy.
