Effect of Radial Artery Compression with a Novel Automatic Pressure-Controlled Radial Compression Device: A...

Area of Science:

• Cardiology
• Medical Devices
• Interventional Procedures

Background:

• Transradial access (TRA) is a common approach for coronary angiography and percutaneous coronary intervention (PCI).
• Hemostasis after TRA procedures typically involves manual compression or conventional devices, which can be time-consuming and associated with complications.
• The development of novel devices for improved post-procedural hemostasis is crucial.

Purpose of the Study:

• To design and evaluate a novel radial compression device with automatic pressure control.
• To assess the feasibility and safety of this new device compared to conventional methods in TRA procedures.

Main Methods:

• A pilot interventional study enrolled 84 patients undergoing TRA coronary angiography/PCI.
• Patients were randomized 1:1 to receive compression with the novel automatic pressure-controlled device (experimental group) or a conventional device (control group).
• Primary endpoint was compression time; secondary endpoints included rebleeding, swelling, radial artery occlusion (RAO), and device-related pressure injury (DPI).

Main Results:

• The experimental group showed significantly reduced compression time (207.4 min vs. 378.1 min, p < 0.001).
• Rates of upper-limb swelling (2.4% vs. 85.7%, p < 0.001) and device-related pressure injury (19.05% vs. 100%, p = 0.005) were significantly lower in the novel device group.
• Pain scores were significantly lower in the experimental group (0.79 vs. 1.83, p < 0.001); no significant difference in rebleeding or RAO was observed.

Conclusions:

• The novel automatic pressure-controlled radial compression device effectively reduces hemostasis time.
• This device significantly decreases adverse complications such as swelling and pressure injury, while also lowering patient pain.
• The device represents a promising and effective tool for hemostasis in transradial coronary invasive procedures.
