Outcome Measures

Primary Outcomes (1)

  • Cumulative operator radiation exposure during PCI (µSv) with a set of 3 radiation detection dosimeters on left wrist, left head, and left chest

    To compare the cumulative radiation dose (µSv) received by the operator between the left distal radial artery approach and the right radial artery approach during PCI. Radiation exposure is measured using a set of three radiation detection dosimeters placed on the operator's left wrist, left head, and left chest.

    Through procedure completion, up to 24 hours

Secondary Outcomes (4)

  • crossover rate (%)

    Through procedure completion, up to 24 hours

  • Fluoroscopy time (min)

    Through procedure completion, up to 24 hours

  • Procedure time (min)

    Through procedure completion, up to 24 hours

  • volume of contrast medium used (mL)

    Through procedure completion, up to 24 hours
