Chronic total occlusion (CTO) of coronary artery is a subset where cardiologists confront technical challenges most of the time during percutaneous coronary intervention (PCI). They experience an additional impediment when CTO intervention is performed in presence of anomalous coronary artery. Here we report a 58 years old gentleman with Diabetes mellitus and hypertension who admitted with Canadian Cardiovascular Society class III angina for 5 months. Coronary angiography revealed dual vessel coronary artery disease with CTO of right coronary artery (RCA) originating from left sinus of Valsalva. PCI with stenting has been done successfully to RCA lesion. Patient got relieved of angina after PCI and remains stable clinically since then.
Keywords: Chronic total occlusion; anomalous; percutaneous coronary intervention.
