Clinical Trial Summary

To evaluate the long-term outcome of chronic total occlusion (CTO) patients underwent contemporary percutaneous coronary intervention (PCI) techniques, we design this single-center, large-sample, prospective registry with five-year clinical follow-up, based on the intravascular ultrasound (IVUS) finding.

Description:

The study plan to include the patients with a CTO lesion in one of the three main epicardial coronary artery (diameter more than 2.5 mm) as the only target lesion. The CTO lesion is defined as 0 grade of thrombolysis in myocardial infarction (TIMI) flow with evidence of occlusion duration more than 3 months. All the PCI procedure will be performed by a group of certified operators in Fuwai Hospital, Beijing, China. All patients evaluate IVUS with automatic pullback (Opticross, Boston Scientific, US) performed after wire crossing. All the included patients are planned for five-year follow-up.
