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.
Parallel
No heparin
Other interventionHemostasis achieved using a dual-artery compression device without administration of heparin after trans-radial diagnostic catheterization
Rates of patent hemostasis
Evaluation of patent hemostasis by pulse oximetry
Time to hemostasis
Nursing time involvement
Calculation of nursing time required for surveillance and care of hemostasis
Evaluation of complications
Compilation of access site complications such as radial artery occlusion, bleeding, presence and grading of hematomas, etc.
