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

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

Why it matters

Who can join: the full rules

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.
