Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Between April 2008 and February 2009, 1014 patients presenting for elective or urgent (but not emergent) cardiac or peripheral catheterization were enrolled.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
10 patients (6 control, 4 US) were excluded after randomization but before procedure for no longer meeting the inclusion criteria, including cancellation of the procedure, lack of a dual-trained operator, or change in access site. Baseline and procedural data were not recorded in this group, and these were not included in any analysis.

Reporting Groups
  Description
Control The combination of anatomic landmarks and fluoroscopic localization of the femoral head will be used to guide femoral arterial access.
Ultrasound Patients randomized to Ultrasound will have anatomic landmarks checked and real-time ultrasound guidance to aid femoral arterial access.

  Hide Outcome Measure 2

Measure Type Secondary
Measure Title Time to Successful Sheath Insertion.
Measure Description

Time was measured from first fluoroscopy of the femoral head (control group), or first application of the ultrasound probe (ultrasound group), until successful sheath insertion.

Time was not recorded for 1 control patient, and 1 ultrasound patient, these patients were excluded from this analysis but included for other analyses.

Time Frame Immediate  
Safety Issue No
