Randomized Comparison of Radiation Exposure to Operators in Coronary Intervention Between Right Radial and Left Distal Radial

The purpose of this study is to show that the radiation exposure of the left distal radial artery approach is superior to the conventional right radial artery approach in terms of less radiation exposure.

Inclusion Criteria:Patients aged 20 years or olderPatients scheduled for coronary angiography and interventionExclusion Criteria:When the pulse of the Left distal radial artery cannot be palpatedWhen the pulse of the right conventional radial artery cannot be palpatedIn case of arteriovenous fistulaAcute myocardial infarction (AMI) patientsIn case femoral artery access must be performed (state of shock, etc.)In case of atrioventricular blockWhen an ergonovine provocation test is requiredWhen the patient refuses to consent to the study
