{Abstract}: <B>BACKGROUND: </B>While there has been an increase in the use of the transradial approach when performing percutaneous coronary angiography and intervention, there is evidence of variations in international practice. Ensuring that operators' practices are supported by evidence is important to ensure optimal outcomes.<BR><B>METHODS: </B>Interventional cardiologists and advanced trainees completed a cross-sectional survey followed by semi-structured interviews to map current practices for transradial coronary artery procedures in Australia and New Zealand and explore factors that influence clinical decision-making around procedural practice.<BR><B>RESULTS: </B>The right radial artery was the preferred access site (88%). Over a third (37%) of the participants indicated that they tested the hand circulation pre-procedure. Over a quarter of respondents (28.6%) reported that they would carry out transradial procedures regardless of the patient's coagulation status. Most participants (77.8%) described radial artery spasm in around 10% of transradial procedures performed. Only 62% of participants assessed for radial artery occlusion post-catheterisation. Interview data revealed four themes that guided clinical decision-making, namely (1) Decision-making based on research, (2) Using clinical experience, (3) Being led by their training, and (4) Individual patient factors.<BR><B>CONCLUSIONS: </B>This study has demonstrated that despite clinical guidelines, substantial practice variation exists in transradial coronary artery catheterisation across Australia and New Zealand. The variation in practice and factors impacting clinical decision-making highlight a need for future strategies to optimise evidence translation and implementation across clinical settings.
