Our technique for transradial coronary angiography and interventions

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Access

Background:

• The transradial approach (TRA) for coronary angiography has evolved significantly over 20 years.
• It demonstrates efficacy in diverse patient groups, including high-risk subsets like those with acute coronary syndromes, the elderly, and obese individuals.
• TRA offers a notable reduction in access-related vascular complications and bleeding compared to the transfemoral approach (TFA).

Purpose of the Study:

• To review clinical and technical aspects of the transradial approach for coronary procedures.
• To highlight the benefits of TRA in reducing bleeding complications, a key factor in adverse event rates.
• To discuss barriers to TRA adoption and strategies for its wider implementation.

Main Methods:

• Review of current literature and clinical practices regarding transradial and transfemoral approaches.
• Discussion of patient selection criteria for TRA.
• Analysis of technical considerations including cath lab setup, access technique, hardware, catheter manipulation, and hemostasis.

Main Results:

• TRA significantly lowers the incidence of vascular complications and bleeding events.
• Despite its benefits, TRA prevalence remains low globally, with a preference for antithrombotic drugs over safer access routes in some regions like the US.
• Successful TRA requires careful patient selection and optimized procedural techniques, including managing anatomical variations.

Conclusions:

• The transradial approach is a safe and effective alternative to the transfemoral approach, particularly for reducing bleeding risks.
• Increased awareness and training are needed to overcome barriers to TRA adoption.
• Optimizing procedural techniques and hardware are crucial for maximizing the benefits of TRA in coronary angiography.
