Official title

Comparison of Operator Radiation Exposure During Percutaneous Coronary Intervention Between Left Distal and Right Conventional Radial Access: A Multicenter, Randomized Trial

Overview

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).

Interventions

  • Procedure Radial Artery Puncture Method for Coronary Angiography and Intervention
    Radial Artery Puncture Method for Coronary Intervention

Primary outcome measures

  • Cumulative operator radiation exposure during PCI (µSv) with a set of 3 radiation detection dosimeters on left wrist, left head, and left chest [Time frame: Through procedure completion, up to 24 hours]
Secondary outcome measures (4)
  • crossover rate (%) [Time frame: Through procedure completion, up to 24 hours]
  • Fluoroscopy time (min) [Time frame: Through procedure completion, up to 24 hours]
  • Procedure time (min) [Time frame: Through procedure completion, up to 24 hours]
  • volume of contrast medium used (mL) [Time frame: Through procedure completion, up to 24 hours]

Eligibility criteria
