Chronic total occlusion revascularization: A complex piece to "complete" the puzzle

Figure 1 Long-term survival according to chronic total occlusion-percutaneous coronary intervention results and completeness of revascularization in a real-world registry investigating elderly > 75 years. Successful chronic total occlusion-percutaneous coronary intervention (CTO-PCI) group was associated with a long-term survival benefit when compared to failed CTO-PCI group at Kaplan–Meier survival analysis. Survival benefit was even greater in the complete coronary revascularization group and preserved up to 5 years. CTO: Chronic total occlusion; PCI: Percutaneous coronary intervention; CR: Complete revascularization; IR: Incomplete revascularization.
