Cardiac Catheterization
Conditions
Brief summary
The purpose of the study is to compare different short durations of radial clamp application following an angiogram via a trans-radial approach.
Detailed description
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.
Interventions
OTHERCompression clamp release
Standard compression clamp is used and will be released at different times according to randomization
