ABSTRACT

Introduction: Coronary artery anomalies are a group of highly variable disorders. Patients with multiple coronary anomalies are very uncommon. Clinical manifestations of coronary artery anomalies can vary from asymptomatic to sudden cardiac death. Case presentation: A symptomatic 43-year-old female patient with single coronary artery, symptomatic myocar- dial bridging on left anterior descending artery and retroaortic course of left circumflex artery is presented. Management and outcome: A reversible perfusion defect was detected only in the anterior wall of the left ventri- cle. After treatment with beta blocker therapy and lifestyle changes, the patient is asymptomatic at 3 months of follow up. Discussion: In most cases, it is difficult to determine the coronary anomalies by catheter coronary angiography alone. Similar to our case, non invasive methods such as multislice computed tomography coronary angiography may be useful to evaluate the coronary anatomy and define the coronary artery anomalies.
