Comparison of Operator Radiation Exposure During Percutaneous Coronary Intervention Between Left Distal and Right Conventional Radial Access

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

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).

Inclusion Criteria:

1. Patients aged 19 years or older
2. Patients scheduled for PCI

Exclusion Criteria:

1. Non-palpable left distal radial artery pulse
2. Non-palpable right radial artery pulse
3. Presence of arteriovenous fistula
4. Need for femoral access as determined by the investigator
5. Refusal to provide informed consent
6. Pregnant or breastfeeding women
