Successful percutaneous coronary intervention to the left anterior descending artery in-stent chronic total occlusion via the left internal mammary artery graft: a case report.

Background: Percutaneous coronary intervention (PCI) via left internal mammary artery (LIMA) graft is technically challenging, requires special consideration due to association with potential complications and therefore, infrequently performed. Data on in-stent chronic total occlusion (CTO) PCI via the LIMA graft is even rarer.

Case Summary: A 59-year-old male with a background history of coronary artery bypass graft surgery and previous PCI, presented with progressive chest pain on mild exertion, in the setting of a chronic coronary syndrome.

Percutaneous coronary intervention to left anterior descending artery/right coronary artery bifurcation: this is not a typo! A case report.

Background: Anomalous origin of the right coronary artery (RCA) is a rare congenital anomaly. A single coronary artery arising from the left sinus of Valsalva, with the RCA originating from the left anterior descending artery (LAD), is extremely rare. We report the case of an anomalous origin of the RCA from the mid LAD with a significant bifurcation lesion, in the setting of an acute coronary syndrome, endangering both the RCA and LAD territories.
