Use of Physiology to Evaluate Procedural Result After PCI CTO
Sponsor: Isala
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.

Interventions
post-PCI Pd/Pa
After angiographically successful CTO PCI, intra-coronary physiologic assessment (RFR, FFR, CFR and IMR) and subsequent OCT of the CTO vessel will be performed. OCT may also be performed during a staged procedure when clinically indicated.
