Abstract

Anomalous origin of the left coronary artery from the non-coronary cusp (LCANCC) is extremely rare and its prognosis and management are still controversial. We present two cases of symptomatic women with LCANCC and a comprehensive review of 19 studies reporting the prevalence, presentation, and management of LCANCC among 174,262 patients. Despite case reports of LCANCC in the pediatric population suggest a much worse prognosis, the optimal risk-stratification scheme for this type of anomaly in adults is yet to be defined, and it should not necessarily be considered a benign condition solely based on its anatomic origin or lack of an interarterial course.

Keywords: chest pain; computed tomography; coronary vessel anomaly.
