CTO, chronic total occlusion; CR-CTO, complete revascularized CTO; ICR, incomplete revascularized CTO; LAD, left anterior descending coronary artery; LCX, left circumflex coronary artery; RCA, right coronary artery; PCI, percutaneous coronary intervention. Percentages are calculated over the total number of CTO.
