This is a non-randomized study of non-significant risk (NSR) that will be conducted at Northwestern's Central Dupage Hospital. Medicare patients > 65 years who are scheduled for a routine physical exam with their PCP that meet inclusion and exclusion criteria will be asked to participate in this study. Consenting patients will be scheduled for 2 back to back ultrasound scans including 5 standard 2D echocardiogram views each. The first scan will be performed by a non-ultrasound specialist using EchoGPS experimental guidance technology and the second control exam will be performed by a trained sonographer using a cleared conventional ultrasound platform.

STUDY SOFTWARE non-significant risk (NSR) Bay Labs EchoGPS software interfaced with the Terason uSmart 3200t FDA 510(k)-cleared, commercially available ultrasound EchoGPS software communicates with the ultrasound image formation engine of the 510(k)-cleared Terason uSmart 3200t through an application programming interface (API). EchoGPS will be used to provide visual guidance, feedback and interpretation assistance to users during image acquisition. For this study, CMAs will use EchoGPS to perform point-of-care echocardiogram examinations.

All of the echo views (or "clips") acquired by non-specialists during the study will be scored for image quality (IQ) by clinicians using the 1-5 ACEP quality grading scale. In this scale, a score of 1 represents the poorest IQ and 5 the highest. Images must have a score of 3 or higher to be considered diagnostic quality. Diagnostic quality images (3+) meet at least minimal criteria for diagnosis to be supported and are therefore clinically acceptable.

Number of minutes for non-specialists to perform studies using EchoGPS software as compared to that of the time for expert sonographer's control studies using FDA 510(k)-cleared, commercially available ultrasound platform. The time of Study Exam will be compared to that of Control Exam on a per subject basis (paired difference) for Phase I of the study.
