case_images: RCA angiography revealing that the aneurysmal fistula (asterisks) had arisen from the distal RCA and drained into the inferior wall of the RV. The shape of the fistula was lageniform. The aneurysmal tract of the fistula was 6 mm wide. The narrowest diameter of the drainage site was 1.5 mm. (A) RAO 30  and (B) LAO 60 .

case_images: RCA angiography revealed a giant and tortuous fistula that originated from the distal RCA and drained into the inferior RV, with an aneurysmal tract proximal to the drainage site (Figure 3).
case_images: Post-procedural RCA angiography showing that the ADO II device (arrows) occluded the fistula with minimal residual shunt, with one disk in the aneurysmal tract (asterisks). (A) RAO 30  and (B) LAO 60 .
