A Prospective Randomized Study Comparing the Incidence of Radial Artery Occlusion (RAO) and the Time To Hemostasis (TTH) When Using a Hemostasis Band Alone and in Conjunction With a Disc Comprised of Potassium Ferrate (StatSeal Advanced) Following Transradial Percutaneous Coronary Intervention (PCI) (NCT03028025)

The primary objectives of this study are to evaluate the performance of StatSeal Advanced used in conjunction with the TR Band (SSA) as compared to the TR Band without SSA (TRB) relative to: the incidence of peri-procedural radial artery occlusion (RAO) at discharge or 24 hours, whichever occurs first, and the Time to Hemostasis (TTH).
  • Device: StatSeal
    Patients randomly assigned to the experimental group will have a Statseal Advance (SSA) disc applied after withdrawing the radial sheath 2-4 cm. A Tegaderm dressing will be applied to secure the disc position. The TR band will be applied over the SSA disc with the center of the balloon (the green dot) over the center of the SSA disc. The TR band will be inflated with 8cc of air (which is typically occlusive pressure), and the sheath removed. No deflation will occur immediately. After 20 minutes of pressure, 3 cc of air will be removed from the TR band. After an additional 20 minutes (40 minutes after procedure), the TR band will be completely deflated, and the TR band left in place. After an additional 20 minutes (60 minutes after procedure) the TR band will be removed.

  • Device: TR Band
    Patients randomly assigned to the control group will have a TR band applied over the arteriotomy site and inflated with 15-18ml of air. After aspirating and clearing the contents of the sheath, the radial sheath will be removed. The TR band will be deflated until bleeding occurs, and 2 ml of air will be reintroduced to provide hemostasis. Patent hemostasis will be documented with plethysmography and oximetry as described below within 5 minutes after band application and removal, and within 30 min of discharge or after 24 hours. The TR band will be left inflated and in place for 2 hours following the procedure for all patients (regardless of diagnostic or PCI procedure), after which deflation attempts will commence.

Accepts Healthy Volunteers
Inclusion Criteria:
  • Patient undergoing diagnostic angiography or PCI via the radial artery
  • Patients with a Barbeau test prior to the procedure showing pattern A,B,or
Exclusion Criteria:
  • Use of a radial sheath larger than 6 Fr (a 7Fr-in-6 Glidesheath Slender ® is allowed).
  • Use of an anticoagulant other than unfractionated heparin or bivalirudin.
  • Any anticipated need for continued anticoagulation post-catheterization. Glycoprotein inhibitors are acceptable.
  • Any active treatment with oral anticoagulants continued during course of procedure.
  • Presence of arteriovenous dialysis fistula in the ipsilateral arm.
  • Any physical deformity or trauma / injury of either wrist that would prevent proper placement or function of the hemostasis band.
  • Raynaud's syndrome or known peripheral vascular disease of the forearm.
  • Mental incompetence or inability to follow the instructions to complete the study.
  • History or presence of Radial Artery Occlusion.
  • Barbeau test showing Pattern D.
  • Patients undergoing catheterization from the femoral or ulnar artery approach.
  • Cardiogenic shock or any clinical instability as assessed by the physician performing the procedure.
This study is a physician initiated, prospective, observational, two arm, randomized study to be performed at up to four experienced 'Radial First' centers (UCSD, UCLA. Arkansas Heart Hospital and LBVA). A maximum of 180 patients having undergone successful radial catheterization will be enrolled in the study, 60 in each arm. 60 patients will be enrolled at the LBVA. Enrollment will continue at each site on discretion of the investigators until each center enrolls a minimum of 30 patients, or a maximum of 180 patients are enrolled. Clinicians will perform the catheterization in accordance with local standard practice, with a minimum of 5,000 units of unfractionated heparin for anticoagulation. At the start of the TRA procedure, prior to radial artery cannulation, a baseline Pleth-ox exam will be performed for all patients and recorded on the CRF. Ulnar compression will be applied to confirm that the radial artery is patent. Patients with a type D pattern exam will be excluded from the study. At the conclusion of a successful transradial procedure, the patient will be randomized to either SSA or TRB, each device applied per protocol & IFU. It is hypothesized that if radial artery compression time can be shortened to 40 minutes or less, the following could result: improved catheterization lab efficiency, greater patient satisfaction and lower complication rates, including RAO, may be improved.
