Systematic versus selective heparin use to prevent radial artery occlusion after catheterization

Comparaison d'un Traitement systématique à l'héparine Versus sélectif Pour la prévention de l'Occlusion Radiale EASY-Héparine

Not applicable Interventional Laval University · NCT06981624

This test compares giving heparin to all patients versus only to selected patients to see which approach better prevents radial artery blockage after diagnostic transradial catheterization.

What this trial studies

Adults referred for diagnostic transradial catheterization are randomized to a routine (systematic) heparin strategy or an elective/selective heparin strategy, with hemostasis managed using a dual-artery compression system. The main outcome is occurrence of radial artery occlusion after the procedure. Patients who cannot consent or cannot receive required antiplatelet or anticoagulant medications are excluded. The trial is conducted at a single tertiary cardiac center with follow-up to document artery patency and immediate postprocedural complications.

Who should consider this trial

Good fit: Adults referred for diagnostic transradial catheterization who can provide informed consent and can receive antiplatelet therapy and intravenous anticoagulation are ideal candidates.

Not a fit: Patients who cannot consent, cannot receive antiplatelet or anticoagulant drugs, or who have local access complications such as hematoma or pseudoaneurysm are unlikely to be eligible or benefit.

Why it matters

Potential benefit: If successful, this approach could allow clinicians to avoid unnecessary heparin in some patients while preserving radial artery patency and reducing bleeding risk.

How similar studies have performed: Prior studies have shown routine periprocedural heparin reduces radial artery occlusion, while selective or no-heparin strategies have been less thoroughly tested in randomized comparisons.

Eligibility criteria

Inclusion Criteria:

* Any patient referred for a diagnostic transradial catheterism

Exclusion Criteria:

* Unable to understand study design or provide informed consent
* Unable to receive antiplatelet therapy with aspirina and/or clopidogrel-prasugrel and/or ticagrelor and intravenous anticoagulant derived from heparine or bivalirudine
* Local condition such as hematoma or pseudo-aneurims precluding radial or ulnar access.
* Presence of plethysmographic waveform with simultaneous radial and ulnar occlusive compression (due to colaterals or interouseous artery) precluding the evaluation of patent hemostasis.
