Use of physioLogy to evaluaTe procedural Result After percutaneous coronary intervention of Chronic Total Occlusion (ULTRA-CTO): protocol for a prospective, single-arm, multicentre, exploratory study.

ABSTRACT:

Introduction

Post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR) is associated with future major adverse cardiac events and may reflect residual ischaemia and suboptimal stent result (SSR). Post-PCI FFR should therefore be considered to identify patients at high risk. Whether abnormal post-PCI FFR and non-hyperaemic pressure ratios, including resting full-cycle ratio (RFR), represent SSR after PCI remains to be determined, especially after chronic total occlusion (CTO) PCI. In addition, little is known about the association between post-PCI intracoronary physiology and SSR with residual anginal complaints.

Methods and analysis
