Randomized study comparing the systematic use of heparin (standard of care) against an elective use of heparin to prevent radial artery occlusion after a percutaneous catheterization using a dual-artery compression system.
Any patient referred for a diagnostic transradial catheterism
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.
