Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Subproject 1 intends to develop a novel algorithm integrating antegrade and retrograde scoring system to optimize the CTO intervention and determine the optimal timing for primary retrograde approach. Current algorithm for CTO intervention.
Subproject 2 aims to examine the strategies and outcomes of CTO involving bifurcations. Bifurcation CTO lesions present unique challenges due to their complex anatomy. Opening of the main vessel while preserving important branches is crucial for ensuring favorable long-term clinical prognosis. This subproject will investigate different strategies and devices employed in bifurcation CTO PCI to assess their efficacy and safety outcomes.
Subproject 3 investigates the treatment strategies for right coronary artery (RCA) CTOs with concomitant left main disease, which present a unique and intricate scenario, requiring careful consideration of revascularization strategies.
