Brief Summary

Establish transthoracic echocardiogram (TTE) exams performed with Bay Labs EchoGPS guidance technology can be used in a primary care setting to accurately identify cardiac disease. In Phase I TTE exams with EchoGPS will be compared to findings from a commercially available, FDA 510(k)-cleared reference device (Terason uSmart 3200t, point-of-care ultrasound) without EchoGPS assistance technology. Study is non-significant risk (NSR).

Recruitment & Eligibility

Status
COMPLETED
Sex
All
Target Recruitment
55
Inclusion Criteria
  1. Patients indicated for a standard physical examination
  2. Patients ≥65 years old

For patients in Phase I, one of the following additional inclusion criteria must be present:

  1. Patient presenting with a new murmur, or history of a murmur but no prior echo within 3 years of the exam
  2. Patient presenting with shortness of breath
  3. Unexplained pedal edema
Exclusion Criteria
  1. Unable to lie flat for study
  2. Significant anatomical abnormality, recent trauma, or recent thoracic/abdominal surgery that would limit the ability to obtain adequate images
  3. Subjects unwilling or unable to give written informed consent
  4. Patients experiencing a known or suspected acute cardiac event Eligibility criteria for Phases II and III of this study will be finalized once results from Phase I are available. The current plan is to have similar criteria for Phases II and III.

GroupInterventionDescription
Medicare Primary Care Provider (PCP) PatientsLimited EchocardiogramThis 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.
Primary Outcome Measures
NameTimeMethod
% of diagnostic quality clips acquired by a non-specialist using experimental guidance software, with quality assessed using the American College of Emergency Physician (ACEP) Suggested Quality Assurance Grading Scale1 year

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.

Secondary Outcome Measures
NameTimeMethod
Number of minutes for non-specialists to perform studies using EchoGPS experimental guidance software1 year

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.
