Two HEmostasis Methods After TransradIal Catheterization: THEMATIC Randomized Clinical Trial

Area of Science:

• Cardiovascular Interventions
• Vascular Access
• Interventional Cardiology

Background:

• Radial artery occlusion (RAO) is a common complication following transradial cardiac catheterization.
• Predictive assessment for vessel patency remains challenging.
• Comparative efficacy of various hemostasis techniques requires further establishment.

Purpose of the Study:

• To compare the incidence of radial artery occlusion (RAO) between two hemostasis devices.
• Evaluate the TR Band device against conventional pressure dressings post-transradial cardiac catheterization.

Main Methods:

• A randomized clinical trial involving adult patients undergoing transradial cardiac catheterization.
• Patients were assigned to either the TR Band device group or a conventional pressure dressing group.
• The primary endpoint was the incidence of RAO, assessed at discharge and 30 days post-procedure.

Main Results:

• No significant difference in RAO incidence was observed between the TR Band group (8% immediate, 5% at 30 days) and the pressure dressing group (6% immediate, 6% at 30 days).
• Peripheral vascular disease was identified as the sole independent predictor for RAO at both discharge and 30-day follow-up.
• A total of 600 patients were included in the analysis.

Conclusions:

• Hemostasis with the TR Band device resulted in a similar incidence of RAO compared to conventional pressure dressings after transradial cardiac catheterization.
• The findings suggest that current hemostasis methods do not significantly alter RAO rates.
• Peripheral vascular disease is a critical factor influencing radial artery patency post-procedure.
