MeSH Terms

Figure 1 Diagnostic coronary angiography demonstrated total occlusion of the RCA (black arrow) (A) with good collaterals from the left anterior descending coronary artery (grey arrow) (B), and severe stenosis of the left anterior descending artery (B). Pre-procedure coronary computed tomography angiogram showed total occlusion of the distal RCA (white arrow) and there was no evidence of abnormal coronary artery drainage. (C, D). RCA = right coronary artery.
Figure 2 Coronary angiogram (left anterior oblique cranial view) showed contrast drainage through multiple channels after recanalization of chronic total occlusion, which mimicked coronary artery perforation (black arrow).
Figure 3 (A, B) Two drug-eluting stents (Orsiro, 2.5×40 and 2.5×40 mm) were implanted in the proximal to middle segment and distal segment of the right coronary artery (A: LAO view, B: AP cranial view). Communication between posterior descending coronary artery and coronary sinus was prominently noted after antegrade flow restoration (C: AP cranial view, D: AP caudal view). AP = anteroposterior; LAO = left anterior oblique.
