In the study group, the TR-Band will be in left in place for 15 minutes before it is gradually deflated by 25% at 15 minute intervals. In the standard of care group, the TR-Band is left in place for 60 minutes before it is gradually deflated by 25% at 15 minute intervals. The aim of the study is to reduce the time the device is in place while minimizing potential complications.

Inclusion Criteria:

• Age 18 years and older
• Have an acceptable Barbeau test (i.e. type A through C)
• Have acceptable coagulation parameters (based on PT, INR, platelet count, and appropriate pre-procedural management of anticoagulants, See Table 1)
• The caliber of the left radial artery based on a pre-procedure sonographic evaluation will need to be greater than or equal to 1.6 mm.
• The appropriate pre-procedural management of anticoagulants is based on the consensus guidelines established by Patel et al16.
• INR less than 1.5
• Platelet count greater than 50,000 platelet/uL
• Prothrombin time less than 15 seconds

Exclusion Criteria:

• If there is an unacceptable risk of bleeding diathesis, or
• If he or she is not a suitable candidate for transradial access based on a Barbeau test type D or a diameter of the left radial artery less than 1.6 mm.

The baseline analysis population included 30 patients randomized into expedited (n=15) and standard (n=15) protocol groups. All participants met inclusion criteria: age >18 years, Barbeau test types A-C, radial artery diameter ≥1.6 mm, and acceptable coagulation parameters (platelet count >50,000/µL, INR <1.5, PT <15s). No significant differences in demographics or clinical characteristics were observed between groups

30 days

The outcomes focus on safety, efficacy, and complications specific to the radial artery access site, and no deaths were mentioned or attributed to the procedures or protocols
