2. Figure 1
Right coronary angiograms before (A) and after (B and C) angioplasty. A, Right anterior oblique view demonstrating disseminated lesions with 95% stenosis in proximal right coronary artery (RCA) (arrow) and occlusion in distal part of RCA with delayed retrograde filling by collaterals. B, Large aneurysmal dilatation (arrow) of distal RCA. C, Stream of contrast flowing from distal RCA into cardiac chamber (arrows).

3. Figure 2
Modified apical 2-chamber echocardiographic view. A, Aneurysmal distal part of right coronary artery (RCA) (6-mm diameter) (arrows). B, Flow between distal part of RCA and right ventricle (RV) visualized by Doppler color flow mapping (arrow) clearly indicates presence of RCA-to-RV fistula. C, Phasic flow in RCA-to-RV fistula recorded with pulsed Doppler; diastolic component of flow (arrow). IVS, Interventricular septum; LV, left ventricle.
