Inclusion criteria
Inclusion criteria: 1. Nineteen years old or older, with coronary artery CTO lesions, and waiting for revascularization treatment 2. Must agree (personally or through his/her legal guardian) with the study protocol and the clinical follow-up schedules, and must sign the informed-consent form voluntarily (This study can proceed after its approval from the IRB of each center.) 3. With a coronary artery CTO lesion on the left anterior descending artery or the right coronary artery
Exclusion criteria
Exclusion criteria: 1. Currently pregnant or breastfeeding or with a possibility of such 2. Contraindicated or hypersensitive to the contrast agent or heparin 3.

Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| The occurrence of each of the following events 12 months after the coronary intervention: - any death- cardiac death- MI- a combination of death and MI- a combination of cardiac death and MI- death, MI, or revascularization of the target vessel- a combination of death, MI, and revascularization of the target vessel- a combination of death, MI, and revascularization of the target lesion- a combination of cardiac death, MI, and revascularization of the target lesion- TVR- TLR- stent thrombosis- a successful treatment outcome (based on visual evaluation via angiography, the stenosis rate of the inner diameter is less than 30%, and there was no death or Q-wave MI or urgent revascularization during the hospitalization period)- changes in the IMR of the CTO lesions- changes in the IMR values of the main retrograde donor feeding artery | — |
Primary
| Measure | Time frame |
|---|---|
| 1.The changes in the FFR of the CTO lesions at the baseline and immediately upon and 12 (+/- 2) months after the coronary intervention for the CTO lesion;2.The changes in the FFR in the main retrograde donor feeding vessel immediately upon and 12 (+/-2) months after the coronary intervention for the CTO lesion | — |
