Figure

• 

  Fig. 1 An accelerated diastolic color flow within the interventricular septum indicating a large septal collateral flow with frontal direction from RCA to left anterior descending artery on parasternal short axis view (A). Markedly dilated RCA ostium on parasternal long axis view (arrowheads) (B). Retrograde diastolic shunt flow toward pulmonary valve at MPA (arrow) (C). Drainage site of abnormal shunt flow at MPA with diastolic reversal flow (D). MPA: main pulmonary artery, RCA: right coronary artery.

• 

  Fig. 2 Coronary angiography showing an enlarged and tortuous RCA from Ao (A). Retrograde filling of LCA through abundant collaterals from RCA and abnormal shunt flow from left main stem to main PA (B). No visualization of LCA in left coronary cusp (C). Sagittal section and 3D reconstruction images of computed tomography of the LCA originating from the PA with retrograde contrast flow from LCA to PA (D and E). Thinning and subendocardial delayed enhancement of anterior LV wall on cardiac magnetic resonance imaging (F). Ao: aorta, LM: left main artery, LCA: left coronary artery, LV: left ventricle, MPA: main pulmonary artery, PA: pulmonary artery, RCA: right coronary artery.
