Summary:

Description
  • Radiopaedia case ID: 12423
  • Image ID: 617800
  • Image stack position: 8/19
  • Plane projection: Axial
  • Aux modality: C+ arterial phase
  • Study description: Cardiac CT
  • Modality: CT
  • System: Cardiac
  • Findings: An anomalous origin of the left coronary artery (LMS), which is located posteriorly on the ascending aorta right above the left sinus of Valsalva (first image). The aorta seems to be "twisted" clockwise with 90 degrees. Distally the LMS can be seen to be bifurcating into the LAD (located medially) and the circumflex artery (Cx). There is also an anomalous origin of the right coronary artery (RCA) which is located anteriorly on the ascending aorta above the left sinus of Valsalva (second image) and has an inter-arterial course between the ascending aorta and pulmonary trunk. This is a potentially life-threatening anomaly.
