Introduction

Preprocedural coronary computed tomography angiography (CTA) can identify calcification and tortuosity, and accurately determine the occlusion length, which may facilitate chronic total occlusion (CTO) crossing. A major limitation of offline CTA is lack of real-time guidance during percutaneous coronary intervention (PCI). This limitation can be overcome using CTA co-registration with a real-time fluoroscopy system.

Methods

CTA/fluoroscopy fusion was used in 27 of 146 cases (18%) performed in 2018-2019, by two experienced operators, at two centres participating in the PROGRESS-CTO registry (NCT02061436). We compared the clinical, angiographic and technical characteristics and procedural outcomes of the patients who underwent CTO ...
