Brief Summary:
Radial artery occlusion may occur after performance of coronary catheterization via the radial artery (transradial approach). In some cases it may be desirable to insert large (7F) catheters via the radial artery, however the impact of increased catheter size on subsequent radial artery patency is unclear. We hypothesize that radial artery occlusion following 7F catheterization is rare and occurs in < 5% of the cases.

Study Type : Observational
Estimated Enrollment : 200 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Observational Study of Radial Artery Patency Following Catheterization With a 7F Sheath
Study Start Date : January 2013
Estimated Primary Completion Date : July 2014
Estimated Study Completion Date : January 2015

Study cohort
Cohort of patients who have previously undergone transradial catheterization with the use of a 7F vascular sheath

Primary Outcome Measures :
  1. Normal reverse Allen test [ Time Frame: Within 2 years of the initial procedure ]
    Radial artery patency will be studied with the reverse Allen test. This test is performed by simultaneously occluding both the radial and ulnar arteries until no pulse signal is detected with a pulse oximeter placed on the index finger. The pressure on the radial artery is then released and reappearance of the pulse signal on the oximeter is documented-signifying antegrade flow in the radial artery. This test is not associated with any reported complications or morbidity.

Secondary Outcome Measures :
  1. Antegrade flow in the radial artery by ultrasound [ Time Frame: Within 2 years of the initial procedure ]
    Radial artery flow will be studied with Doppler ultrasound
