Brief summary
The primary objective of this study is to evaluate the feasibility of a novel app to facilitate heart failure patients to acquire lung ultrasound images and evaluate the quality of those images to expert scans, and to evaluate for relationships between the ultrasound data and pulmonary pressure data from the Abbott CardioMEMS system.
Detailed description
Feasibility study to compare an investigational Artificial Intelligence (AI) Auto B-line tool measurement on Lung Ultrasound (US) images acquired with an AI assisted guidance tool by novice ultrasound clinicians and heart failure (HF) patients, to standard of care heart failure monitoring of pulmonary artery pressure measured by the Abbott CardioMEMS system.
