An update on radial approach for percutaneous coronary intervention in patients with chronic total occlusion

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Access

Background:

• The radial artery approach is increasingly adopted for percutaneous coronary interventions (PCI).
• Chronic total occlusions (CTO) remain a complex subset of PCI cases, posing challenges for interventional cardiologists.
• Existing data from high-volume transradial centers support a shift towards radial access for PCI.

Purpose of the Study:

• To evaluate the suitability and technical considerations of the radial approach for PCI in CTO lesions.
• To provide an update on technical aspects and data relevant for planning CTO procedures via radial access.
• To assess the potential of radial access in reducing bleeding risks for CTO patients.

Main Methods:

• Review of data from selected high-volume transradial centers.
• Analysis of technical aspects and theoretical data pertinent to CTO procedures.
• Discussion of upper limb vascular anatomy, sheath/catheter selection, and CTO lesion management.

Main Results:

• The radial approach is feasible and potentially advantageous for PCI in CTO.
• Successful CTO PCI via radial access requires comprehensive knowledge of anatomy and specialized techniques.
• Transradial PCI for CTO can offer reduced bleeding complications compared to other approaches.

Conclusions:

• The radial approach is a suitable and evolving access site for PCI in CTO patients.
• Mastery of specific technical skills and anatomical knowledge is crucial for safe and effective radial CTO PCI.
• Adoption of radial access for CTO PCI can enhance patient safety by minimizing bleeding risks.
