Using a new device to prevent radial artery occlusion after catheterization

A Prospective Registry for the Evaluation of the Safety, Efficacy and Clinical Impact of the Double Hemostasis System Terry2 (TM) on Patients Undergoing a Trans-radial or Trans-cubital Catheterism.

Laval University · NCT04933136

This study is testing a new band to see if it can help prevent blockage in the wrist artery after heart procedures, making it safer and more comfortable for patients.

What this trial studies

This observational study aims to evaluate the effectiveness and safety of the Terry2™ band in achieving non-occlusive hemostasis of the radial artery after transradial catheterization. The study focuses on improving patient comfort and minimizing the risk of radial artery occlusion (RAO), a common complication that can limit future access to the artery. By applying simultaneous pressure to both the radial and cubital arteries, the Terry2™ band aims to reduce the incidence of RAO to less than 2%. The study will involve patients undergoing diagnostic or interventional catheterization through radial or cubital approaches.

Who should consider this trial

Good fit: Ideal candidates include patients referred for diagnostic or interventional catheterization via radial or cubital approaches.

Not a fit: Patients with local conditions like hematomas or pseudo-aneurysms that prevent radial or cubital access may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of radial artery occlusion, improving future access for catheterization and surgical procedures.

How similar studies have performed: While the concept of non-occlusive hemostasis has been explored, the use of the Terry2™ band represents a novel approach that has not been widely tested in clinical settings.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Any patient referred for diagnostic or interventional catheterization through radial or cubital approach

Exclusion Criteria:

* Unable to understand the study design and sign an informed consent
* Unable to receive antiplatelet therapy with aspirin and/or clopidogrel-prasugrel and/or ticagrelor and intravenous anticoagulant treatment with heparin or bivalirudin
* Presence of any local conditions like hematoma or pseudo-aneurysms precluding radial or cubital access.
* Presence of PPG while simultaneously compressing the radial and cubital arteries (due to collateral branches or interosseous artery), which prevents the establishment of non-occlusive hemostasis with the Terry2(TM) band.
