Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

* Improving patient comfort and implementing the protocols required to minimize the risk of RAO must be part of quality control.
* Several procedural parameters are related to the risk of RAO but hemostasis is a critical period.
* Despite the fact that non-occlusive hemostasis of the radial artery is a recognized and effective technique for reducing the risk of RAO, it is rarely practiced because it is tedious, involves additional care and is not always effective with current hemostasis systems.
* Prophylactic compression of the cubital artery during radial artery hemostasis has been shown to be effective in maintaining non-occlusive hemostasis but requires 2 devices and does not simplify care procedures.
* The Terry2™ band is a new dual device that offers effortless non-occlusive radial hemostasis and does not require repeated intervention by nursing staff.

The primary objectives of this observational study are to demonstrate the benefits, safety and impact on care of using Terry2™ band in patients undergoing diagnostic or interventional catheterization by radial (or ulnar) approach.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Radial Artery Occlusion (RAO) is the most common peri-procedural complication after a trans-radial catheterization,

Although usually asymptomatic, RAO may prevent the use of radial artery access in future catheterization should the patient need one; the use And the artery cannot be used as an alternate graft in case the patient is referred for aorto-coronary bypass surgery.

Recent data has demonstrated a clinical benefit for the use of radial artery over a venous graft for patients requiring artery bypass grafts.

Current international recommendations suggest limiting the risk of RAO to less than 5% upon discharge from hospital. To do this a change of method, ie performing a non-occlusive hemostasis of the radial artery is the most effective method to limit the risk of RAO. Unfortunately, this method takes time and requires repeated interventions by nurses, which has limited its application worldwide. In addition, simple hemostasis systems (on radial artery alone) can only achieve non-occlusive hemostasis in 60-75% of cases.

On the other hand, it has been shown that by applying simultaneous pressure to the two arteries of the wrist (the radial artery and the cubital artery), one could obtain a non-occlusive hemostasis of the radial artery in more than 95% of cases and the level of RAO was reduced \< 2%. However, the handling of 2 separate hemostasis systems again requires repeated intervention by the nursing staff and therefore burdens the monitoring procedure.

The device Terry2™ band applies simultaneous differential compression to the radial artery and the cubital artery. Its mechanism of action aims to accelerate the time of hemostasis, reduce nursing work, improve patient comfort and minimize the risk of radial artery occlusion during and after hemostasis.

Hypotheses:

* The Terry2™ band provides fast and safe non-occlusive radial hemostasis that limits the risk of RAO.
* The Terry2™ band is associated with increased patient comfort, reduced staff work and a minimized risk of RAO after radial catheterization.

Procedures:

At the end of the radial approach procedure, patients will have a Terry2 band installed™ according to the instructions for use. Staff will be trained on the use of the device by means of an educational video. Once the device is installed, a check for the presence of non-occlusive hemostasis will be done before the patient has returned to their room.

Once the hemostasis is completed, the permeability of the radial artery is again checked by pulse oximetry. In case of doubt about the permeability of the instrumented artery, it is recommended to validate with an ultrasound-doppler.

Rates of RAO and other access site complications, total nursing time involved and patient comfort will be evaluated.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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
