Transradial access in percutaneous coronary interventions: technique and procedure

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Access

Background:

• Radial artery access is increasingly utilized for percutaneous coronary interventions due to lower complication rates.
• This approach enhances patient comfort and reduces healthcare costs.
• Transradial access is associated with better cardiac outcomes, particularly in acute coronary syndrome patients, due to reduced bleeding complications.

Purpose of the Study:

• To highlight the benefits of transradial percutaneous coronary intervention.
• To identify factors influencing procedural success and complications.
• To outline strategies for optimizing transradial catheterization.

Main Methods:

• Review of diagnostic coronary angiography and transradial percutaneous coronary intervention outcomes.
• Analysis of anatomical and patient-related risk factors for radial artery complications.
• Evaluation of pharmacological and technical adjuncts for successful catheterization.

Main Results:

• Transradial access demonstrates significantly lower complication rates and improved patient comfort.
• Factors like anomalous anatomy and patient characteristics influence procedural success.
• Use of smaller catheters (4-5 Fr), specific needles (≤ 21-gauge), guidewires (≤ 0.018 in), and adjuvant pharmacotherapy (heparin, verapamil, nitroglycerine, ibuprofen) mitigate risks.
• Inspiration maneuvers facilitate safe passage to the ascending aorta.

Conclusions:

• Transradial percutaneous coronary intervention is a safe and effective alternative with superior patient outcomes.
• Meticulous attention to radial artery anatomy and proactive pharmacological management are crucial for minimizing complications.
• Optimized techniques and equipment ensure successful transradial catheterization and sheath access.
