This study aims to compare the operator's radiation exposure between left distal radial access (LDRA) and right transradial access (RTRA) in patients undergoing percutaneous coronary intervention (PCI).
Patients aged 19 years or older
Patients scheduled for PCI
Non-palpable left distal radial artery pulse
Non-palpable right radial artery pulse
Presence of arteriovenous fistula
Need for femoral access as determined by the investigator

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.
crossover rate (%)
The percentage of participants who required a change in the initial arterial access site to a different site to successfully complete the PCI procedure.
Fluoroscopy time (min)
Total duration of exposure to fluoroscopy during the PCI procedure, measured in minutes.
Procedure time (min)
Total time from the first skin incision or needle puncture to the removal of the last catheter/sheath, measured in minutes.
volume of contrast medium used (mL)
Total volume of radiopaque contrast media administered to the participant during the procedure, measured in milliliters (mL).
