Congenital Absence of Left Circumflex Coronary Artery
Congenital absence of left circumflex artery is a rare congenitalanomaly of the coronary arteries. The prevalence of theanomaly in different studies ranges from 0.6% to 1.3%. Ofthese, 80% are benign and asymptomatic and 20% are clinicallyimportant. We report a 56-year-old man presented withacute res...

| description | Congenital absence of left circumflex artery is a rare congenitalanomaly of the coronary arteries. The prevalence of theanomaly in different studies ranges from 0.6% to 1.3%. Ofthese, 80% are benign and asymptomatic and 20% are clinicallyimportant. We report a 56-year-old man presented withacute resting chest pain who was diagnosed as having acuteanterolateral infarction accompanied by electrocardiographicchanges and elevated cardiac enzymes. Coronary angiographyin different views was conducted, however, no left circumflexartery was found. The territory supplied by the artery had beenperfused by the super dominant right coronary artery. Therewas no left circumflex coronary artery with anomalous origin.Sever stenosis of left anterior ascending artery superimposedto the absent left circumflex artery was presented as acute anterolateralinfarction. Although absence of the artery is mostlyconsidered as a benign condition, atherosclerotic lesions maybe more important in such cases because of diminished compensatingmechanisms. |
