Recruiting NA Chronic Total Occlusion of Coronary Artery

Compares treatment options for Chronic Total Occlusion of Coronary Artery

Official title To Evaluate Whether IVUS-guided Drug-eluting Stent (DES) Implantation Leads to Better Clinical Outcomes Compared to Conventional Angiography in the Treatment of Chronic Complete Occlusion (CTO) Disease.

ClinicalTrials.gov ID: NCT04944615

What this study is testing

What it's testing
This study aims to evaluate the treatment of Chronic total occlusion (CTO) disease. Whether Intravascular Ultrasonography (IVUS) guiding the implantation of drug-eluting stents (DES) will provide better long-term clinical outcomes compared with conventional angiography
