Summary

IVUS will be used to evaluate the ratio of false lumen to occluded segment, the ratio of false lumen to stent length, the location characteristics of false lumen and its prognostic value for perioperative complications, 1-year late lumen loss and MACCE events in patients with coronary CTO.

Detailed description

At present, novel technologies of CTO interventional therapy become mature. These technologies usually artificially cause dissection of coronary artery. The events such as collateral vessel loss, vascular injury and tear, perforation, pericardial tamponade caused by false lumen may theoretically affect the perioperative and long-term prognosis of patients. In this study, intravascular ultrasound (IVUS) was used to evaluate the characteristics of true lumen and false lumen in CTO segment, so as to determine its impact on the prognosis of patients.

Conditions

• Chronic Total Occlusion of Coronary Artery
