Radiation Exposure to Operators in Coronary Procedures Between Left Distal and Right Conventional Radial Access
- Randomised controlled trial
- prospective
- multicentre
- open-label
Authors' conclusion
During coronary procedures, no significant differences were observed in the operator radiation exposure at the left wrist, head, and chest between the left DRA and right TRA groups.
Study context
- Population
- Patients scheduled for coronary procedures1,001 analysed
- Participants
- 1,010 patients
- Comparison
- Left distal radial access vs right transradial access
- Left distal radial access (DRA)n = 501
- Right transradial access (TRA)n = 500reference
- Primary endpoint
- Operator radiation exposure (real-time dosimeters on left wrist, head and chest)
Primary result
As reported in the abstract
Operator radiation exposure
| Group | Left wrist | Head | Chest |
|---|---|---|---|
| Left DRA | 4.76 μSv | 2.00 μSv | 1.28 μSv |
| Right TRA | 5.20 μSv | 1.83 μSv | 1.07 μSv |
- Left DRA vs Right TRA: P = 0.342 — left wrist
- Left DRA vs Right TRA: P = 0.416 — head
- Left DRA vs Right TRA: P = 0.199 — chest
Secondary outcomes
Access-site crossover
- Crossover, left DRA vs right TRA: not significantly different
- 6.6% vs 5.2%; P = 0.416
Total fluoroscopy time
- Fluoroscopy time, left DRA vs right TRA: not significantly different
- 4.5 minutes vs 4.2 minutes; P = 0.673
Total procedure time
- Procedure time, left DRA vs right TRA: not significantly different
- 16.0 minutes vs 15.0 minutes; P = 0.314
Total contrast volume
- Contrast volume, left DRA vs right TRA: not significantly different
- 80.0 mL vs 80.0 mL; P = 0.222
