Coronary and bypass graft angiography via the right radial approach using a single catheter

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Access

Background:

• Transradial cardiac catheterization offers advantages but can be challenging in patients with prior coronary artery bypass graft (CABG) surgery.
• The left internal mammary artery (LIMA) graft has historically been a concern for right radial access.
• Previous reports suggest feasibility and safety of LIMA angiography via radial approach.

Observation:

• This case report details a transradial coronary and bypass graft angiography procedure.
• The procedure was performed using a right radial artery access.
• A single catheter was utilized for the entire angiography, including LIMA angiography.

Findings:

• Transradial coronary and bypass graft angiography, including LIMA angiography, is technically feasible from the right radial approach.
• Successful angiography was achieved using a single catheter.
• The study discusses various catheter options suitable for LIMA angiography via right radial access.

Implications:

• This technique expands the utility of transradial access in complex cardiac patients.
• It may offer a safer and more convenient alternative to traditional femoral access for graft angiography.
• Further research into optimal catheter selection can refine this procedure.
