Figure 1: CT images of CAA associated with coronary fistulas.
a) Coronary artery aneurysm measuring 3.0 × 2.0 cm located at the
left-anterior aspect of the pulmonary artery trunk (white arrow). b)
Pericardial effusion is noted. c) Three-dimensional CT image showing CAA
associated with coronary fistulas (white arrowheads).

Figure 2: Intraoperative photographs.
a) CAA is located at lateral surface of the pulmonary trunk (dotted
area). b) Fistulous opening which communicates the pulmonary artery and
coronary aneurysm is observed (black arrow). c) From within the
aneurysm, drainage site of feeding arteries is closed (white arrow).

Figure 3: Intraoperative fluorescence imaging.
a, b) Preoperative images showing anomalous fistulous vessels
in front of the pulmonary artery (white arrows). c)Postoperative image showing ligated feeding arteries arising from the
proximal right coronary artery (black arrow). Anomalous fistulous
vessels and CAA are not visualized.
