Anomalies d'implantation et de trajet des artères coronaires : apport du scanner multicoupe

Abnormalities in coronary artery origin and course are rare and often asymptomatic. However, visualizing them is of great interest because they can be responsible for iatrogenic trauma during cardiac surgery, and, for some of them, for myocardial infarction, which can lead to sudden death. We show the contribution of multislice CT in the positive diagnosis of these anatomic variations and in the differential diagnosis between benign and malignant forms, potentially responsible for myocardial ischemia.
