Key result
Successful percutaneous coronary intervention for chronic total occlusion was associated with improved long-term survival compared with failed procedures (P=0.0147).
Why the study?
Although successful CTO-PCI has been linked to symptom relief and clinical benefits, the long-term benefit of percutaneous recanalization of CTO remains unclear.
Does successful CTO-PCI improve long-term survival in patients with chronic total occlusion compared to failed CTO-PCI?

May support survival benefit of successful CTO-PCI; leaves open causal confirmation in randomized trials.
Cohort (n=477)
Does successful CTO-PCI improve long-term survival in patients with chronic total occlusion compared to failed CTO-PCI?
p-value: p=0.0147
Successful CTO-PCI, particularly of the left anterior descending artery, is associated with improved long-term survival compared to failed CTO-PCI over a >10-year follow-up.
Yoneda et al. (2020) conducted a cohort in Chronic total coronary occlusion (n=477). Successful CTO-PCI vs. Failed CTO-PCI was evaluated on Long-term survival (p=0.0147). Successful percutaneous coronary intervention for chronic total occlusion was associated with improved long-term survival compared with failed procedures (P=0.0147).
