Rapid Clamp Release Post Trans-radial Cardiac Catheterization

This is a single-center, prospective, randomized study that will enroll patients that are referred for an angiogram and will compare 3 different durations of radial clamp applications. Patients will be randomly assigned to either 10, 20 or 30-minute clamp applications. The clamps will be gradually released at the end of the assigned durations and participants will be assessed for the radial artery occlusion, hematoma, and other bleeding events.
