Strategies to overcome challenges of transradial coronary angiography and intervention

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Access

Background:

• The transradial approach is increasingly preferred for coronary angiography and interventions due to reduced vascular complications.
• Compared to the femoral approach, radial access offers benefits such as early ambulation, improved patient well-being, and cost-effectiveness.

Purpose of the Study:

• To identify and address the challenges associated with catheter engagement during transradial coronary angiography.
• To provide practical techniques for overcoming difficulties encountered in transradial procedures.

Main Methods:

• Review of techniques for managing radial artery spasm.
• Strategies for navigating tortuous radial-brachial arteries and subclavian-aorta curves.
• Guidance on catheter selection and manipulation for successful coronary artery cannulation.

Main Results:

• Successful coronary engagement and angiography can be achieved consistently via the transradial route.
• Specific techniques effectively mitigate challenges posed by arterial anatomy and spasm.
• The transradial approach remains a viable and advantageous method for coronary procedures.

Conclusions:

• Transradial coronary angiography presents unique challenges, primarily related to catheter manipulation and anatomical variations.
• Implementing suggested techniques can significantly improve success rates and patient outcomes.
• The transradial approach is a safe and effective alternative to the transfemoral route for coronary angiography.
