TRIO CTO (Taiwan Research Initiative on Coronary Total Occlusion)

Официальное название

The Multicenter Study to Evaluate Clinical and Angiographic Factors in Patients With Coronary Artery Chronic Total Occlusion in Taiwan

Обзор

Coronary chronic total occlusions (CTO) present a significant challenge in the field of interventional cardiology. These complex lesions, characterized by complete blockage of a coronary artery for a prolonged duration, often require specialized techniques and strategies to achieve successful revascularization.

Подробное описание

Using this consortium, we will establish a multicenter cohort to evaluate the clinical parameters, angiographic characteristics, interventional techniques, and clinical outcomes involved in coronary CTO intervention. 3 subprojects are listed here.

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.
