High-Resolution CT for Heart

NCT07169201 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 500

Summary

This prospective observational study aims to evaluate a high-resolution coronary CT platform (uCT SiriuX Pro) for non-invasive assessment of coronary plaque biomechanics and functional physiology in high-risk patients. The system enables CT-derived radial wall strain (CT-RWS), a novel biomarker reflecting plaque vulnerability, with potential correlation to invasive OCT findings and clinical outcomes.

The study will assess the diagnostic performance and prognostic value of CT-RWS, along with a new CT-based index of systolic flow perfusion (CT-SFPR) for evaluating the hemodynamic relevance of myocardial bridging, compared to nuclear perfusion imaging. Additionally, left ventricular ejection fraction derived from dynamic CTA (CT-EF) will be compared with echocardiography to evaluate its feasibility and accuracy. This is the first study to comprehensively validate CT-RWS, CT-SFPR, and CT-EF using a fully non-invasive, high-temporal-resolution CT platform.
