Radial artery access for cardiac catheterization can require multiple attempts. Multiple
attempts increase the time required, patient discomfort, and the risk of arterial spasm.
Ultrasound guidance has been shown in other studies to reduce the number of attempts and
complications in central venous and femoral artery access. This study will test if the
addition of ultrasound guidance reduces the number of attempts and time required to access
the radial artery.

Inclusion Criteria:

- Adult patients presenting for cardiac or peripheral catheterization with planned
radial approach.

- Barbeau's or Allen's test indicating at least some degree of collateral circulation
in palmar vessels

- Functional ultrasound equipment with ultrasound trained attending operator

Exclusion Criteria:

- Inability to provide informed consent

- Femoral access

- Emergency procedure (Shock, STEMI)

- End-stage renal disease on hemodialysis

- Previous ipsilateral puncture within 1 week
