The purpose of this study is to establish the rate of radial artery occlusion post diagnostic/interventional cardiac catheterization through different modalities, and to compare current assessment methods (such as Allen's test, Modified Barbeau test and duplex ultrasonography) to specialized imaging techniques for sensitivity and specificity of radial artery occlusion detection post transradial catheterization.
The study hypothesis is that specialized imaging can provide a specific focused analysis of hand characteristics to identify physiologic abnormalities as a result of radial artery occlusion post transradial catheterization.
