  • Figure 1
    Case A: Absent left circumflex artery
     

    Volume rendered image shows a superdominant RCA in the base of the heart with an absent LCX.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Special Focus: Congenital;

    Volume rendered image shows the RCA extending into the left atrio-ventricular groove.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Special Focus: Congenital;

    Axial image shows normal location of the RCA and the LAD with an absent LCX in the left atrio-ventricular groove.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Congenital;

    Axial MIP image at the base of the heart shows branches of the RCA supplying the lateral wall of the left ventricle.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Congenital;
     
     
  • Figure 2
    Case B: Absent right coronary artery
     

    Volume rendered image shows complete absence of the RCA at the level of the right coronary ostium.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Special Focus: Congenital;

    Volume rendered image shows an absent RCA with a large LCX extending into the right atrio-ventricular groove.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Special Focus: Congenital;

    Axial CT image shows absent RCA in the right atrio-ventricular groove with normal position of the LAD and LCX.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Congenital;

    Coronal MIP image shows the large LCX extending across the base of the heart to supply the right side.
