Transradial artery coronary angioplasty

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Surgery

Background:

• Percutaneous coronary balloon angioplasty (PTCA) traditionally uses femoral or brachial arteries, posing risks of vascular complications.
• These complications include bleeding and damage to the artery and surrounding structures.
• The radial artery offers a potential alternative due to its dual blood supply and fewer adjacent structures.

Purpose of the Study:

• To evaluate the feasibility and safety of performing PTCA with miniaturized equipment via the radial artery.
• To assess the rate of puncture site-related complications.
• To determine the success rate of PTCA using the radial artery approach.

Main Methods:

• A prospective study involving 100 patients with collateral blood supply to the right hand.
• Utilized 6F guiding catheters and rapid-exchange balloon catheters for PTCA.
• Assessed coronary lesions (Type A, B, C) using computerized quantitative coronary analysis.
• Evaluated radial artery function and structure post-procedure using clinical assessment, Doppler, and ultrasound.

Main Results:

• Successful coronary catheterization via the radial artery was achieved in 94% of patients (94/100).
• Procedural success for PTCA was high, with 98% of lesions treated successfully via the radial artery (92/94 patients).
• No major puncture site-related complications were reported, with easy hemostasis achieved.

Conclusions:

• Percutaneous coronary balloon angioplasty via the radial artery using miniaturized equipment is a feasible and safe alternative.
• The radial artery approach significantly reduces the risk of major vascular complications at the puncture site.
• This technique offers a high success rate for treating coronary lesions.
