NCT04691778

Brief Summary

The Gladius First trial is designed as a single-centre, open, prospective, randomized clinical trial aimed to assess the efficiency and safety of coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using the antegrade wiring strategy with a first-choice intermediate Gladius guidewire. To this end, consecutive patients referred to CTO PCI with intended primary antegrade wire escalation strategy, will be randomized in a 1:1 fashion to antegrade wiring starting with the Gladius guidewire or antegrade wiring using the standard guidewire escalation strategy.

Outcome Measures

Primary Outcomes (1)

  • time-efficiency of antegrade wiring strategy

    time-efficiency of antegrade wiring strategy defined as the time from advancement of the first wire into the proximal cap to either the time of successful antegrade wiring through the lesion or the time of cessation of antegrade wiring and changing CTO PCI strategy according to the hybrid algorithm

    during procedure (intraprocedural)

Secondary Outcomes (15)

  • time-efficiency of successful antegrade wiring strategy

    during procedure (intraprocedural)

  • time-efficiency of successful antegrade approach

    during procedure (intraprocedural)

  • time-efficiency of antegrade approach

    during procedure (intraprocedural)

  • time-efficiency of successful CTO recanalization using any technique

    during procedure (intraprocedural)

  • total procedural time

  • +10 more secondary outcomes

Study Arms (2)

CTO PCI using antegrade wiring strategy starting with the Gladius guidewire

ACTIVE COMPARATOR

Study subjects will undergo CTO PCI with primary antegrade wiring strategy starting with the Gladius guidewire. In case of failed CTO crossing with the Gladius wire, the decision on continuing antegrade wire escalation with a different wire or switching to a different CTO PCI strategy will be left to the discretion of the operator.

Procedure: CTO PCI with the first-choice Gladius guidewire

CTO PCI using standard antegrade wire escalation strategy

OTHER

Control subjects will undergo CTO PCI using standard antegrade wiring strategy starting with the lower/intermediate penetration force guidewires and, if necessary, escalating up to high gram-force guidewires, but without the use of first-choice Gladius guidewire.

Procedure: CTO PCI without the first-choice Gladius guidewire
