About this trial
This is a phase IV, prospective, open label, randomized-controlled study that will compare radial access with state-of-the-art femoral access in patients without ST-segment elevation acute myocardial infarction undergoing cardiac catheterization. Subjects will be randomized 1:1 into 2 treatment groups: radial access and state-of-the-art femoral access. Randomization will be performed in blocks of 50 per site. Similarly, a second sub-randomization will be performed in the femoral access group into use of 18 vs 21 gauge needles, also in a 1:1 fashion.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 18 years and older
Undergoing diagnostic angiography for ischemic symptoms with possible PCI, or undergoing planned urgent or elective PCI
Has provided informed consent and agrees to participate
Patients must be equally eligible to undergo cardiac catheterization via radial or femoral access
Disqualifiers
Primary PCI for STEMI
Planned right heart catheterization
Valvular heart disease requiring valve surgery within 30 days after the index procedure
Hemodialysis access (arteriovenous fistula or graft) in the arm to be used for PCI in case of assignment to radial approach (the opposite arm may be used for radial access if a dialysis graft is present in one)
Trial design

Treatments tested in this trial
Radial Access
Procedure/SurgeryRadial Access
State-of-the-art femoral access with 18 gauge needle
Procedure/SurgeryState-of-the-art femoral access with 18 gauge needle
State-of-the-art femoral access with 21 gauge needle
Procedure/SurgeryState-of-the-art femoral access with 21 gauge needle. For patients randomized to micropuncture (21G) the micropuncture wire must be advanced under fluoroscopy to avoid inadvertent wiring of side-branches.
Treatment groups
Trial outcomes
Primary outcomes
Incidence of the composite of vascular access complications and bleeding (BARC 2, 3, or 5)
Secondary outcomes
Total number of BARC type 2, 3, or 5 bleeding events
Number of Vascular access complications defined as the composite of arteriovenous fistula, arterial pseudoaneurysm, or arterial occlusion requiring intervention;
Number of participants with Radial artery occlusion
Number of participants with Access site crossover
The inability to complete the procedure from the assigned arterial access site, requiring conversion from radial to femoral access or vice versa for procedure completion
