  • Figure 1
    Figure 1 (case one)

    The arrow shows the presence of the hypodense linear structure that connects the caudal portion of the interatrial septum with the caudal portion of the posterior wall of the left atrium.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 2
    Figure 2 (case one)

    The image presents the length of the structure, which is about 11.8 mm.
