Brief Summary

The JVPHome is a novel medical device that utilizes machine vision in order to facilitate assessment of jugular venous pressure (JVP) height relative to the sternal angle with the ultimate goal of enabling remote JVP monitoring. The current study aims to evaluate the ability of the JVPHome to enable remote identification of JVP height relative to ultrasound among congestive heart failure (CHF) patients when the device is applied by the study team in the clinic.

Detailed Description

CHF is a common and devastating health problem estimated to affect upwards of 26 million individuals worldwide. Following an initial hospitalization for heart failure, approximately 25% of patients are readmitted within the first 30 days of discharge. Repeat heart failure hospitalizations are a major burden on both patients and healthcare systems. To date, there is an absence of non-invasive solutions proven to reduce the risk of re-hospitalization for CHF.

The key feature of the physical examination for assessing the volume status of CHF patients is the JVP, which manifests as a biphasic pulsation along the neck. The height of the JVP relative to the sternal angle is a reflection of right atrial pressure, which increases in response to higher pressures transmitted from the left side of the heart. Pathologic elevation of left sided heart pressures can result in fluid congestion in the lungs, which can cause patients to develop shortness of breath and reduced blood oxygen levels. Although a crucial marker of volume status, accurate identification of the JVP can be challenging for physicians due to its pulsations often being subtle.

The JVPHome is a novel medical device designed to facilitate visualization of JVP height relative to the sternal angle through the use of machine vision. The current study aims to evaluate the JVPHome in a clinic setting when the device is applied to CHF patients by clinicians. Following its application, the JVPHome will be allowed to record a video of the JVP and images will subsequently be transmitted to a secure cloud and undergo analysis with machine vision software. JVP height of study participants will be concurrently assessed through the use of ultrasound (gold standard). Clinicians that are blinded to ultrasound determined JVP height values will assess JVP height values remotely based on the machine enhanced images generated by the JVPHome. Analyses will then assess the accuracy of the JVPHome relative to ultrasound and expert clinical assessment.
