iRADIAL-CABG Trial Design

2Treatment groups
Active Control
Group I: Smartphone assessmentActive Control1 Intervention
The smartphone app (Heart Rate, Azumio software) will be used to assess radial and ulnar artery patency. Briefly, the iPhone camera will be placed over the participant's index finger and patency assessed before and immediately following isolated contralateral artery compression for a maximum of two minutes.
Group II: Modified Allen's TestActive Control1 Intervention
The Modified Allen's Test (MAT) will be performed in a well-lit room on the participant's hand. This technique will involve compression of both the radial and ulnar arteries by the investigator to assess patency of the contralateral artery. The participant will then be asked to clench and open their hand several times. The participant will then be asked to maintain their hand in an open position. The investigator will then release the compression over the ulnar artery and observe for palmar blush. The length of time to achieve maximal palmar blush will be recorded. This technique will then be repeated by maintaining compression over the ulnar artery and releasing of the compression over the radial artery.
