Use of Physiology to Evaluate Procedural Result After PCI CTO

Sponsor: Isala

View on ClinicalTrials.gov

Summary

ULTRA-CTO is a prospective multicentre non-randomised investigator-initiated trial designed to enrol 200 subjects with an indication for percutaneous coronary intervention (PCI) of chronic total occluded (CTO) coronary artery. The main objective of the study is to assess the predictive value of post-PCI resting full-cycle ratio (RFR) and fractional flow reserve (FFR) with regard to Fractional flow reserve (SSR) in CTO patients.
