Congenital Absence of the Left Main Coronary Artery in a 67-Year-Old Healthy Male: A Case Report and Mini Review

Congenital absence of the left main coronary artery is a very rare entity. The literature surrounding this presentation describes it as a fairly common cause of sudden death especially in early life. Some schools of thought hypothesize that for the few cohorts who live into their adulthood with this anomaly, serious cardiovascular complications usually ensue. We present a case of a generally healthy and asymptomatic 67-year-old gentleman with a history of diagnosed congenital absence of the left main coronary artery since age six without any active cardiovascular complaints at baseline.
