Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Post-Marketing Study for On Label Evaluation of the GE Vscan Ultrasound Imaging System

Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Percentage of Correct Diagnosis [ Time Frame: 2 years ]
    A comparison of the percentages of correct diagnosis by VSCAN and clinical exam using a McNemar test for matched pairs with ECHO used as the gold standard.

Enrollment: 1000
Study Start Date: February 2010
Study Completion Date: July 2012
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Detailed Description:

The study requires 2 visits to OHSU.

At the first visit a cardiac physical exam will be done by a cardiologist.

At a second visit, a different cardiologist will perform an ultrasound scan (as part of your standard of care) using a Vscan Ultrasound System. The first and the second visit may be done on the same day depending upon your schedule and if it's convenient for you to stay. The total exam time for both the visits, including standard exam and the study device exam will be about 45 minutes.
