Wearable HALD vest to record heart and lung sounds during clinic visits

An Observational Prospective Study to Assess the Feasibility of a Cardiorespiratory Medical Device, HALD (Heart and Lung Diagnostic) and Its Ability to Obtain Heart and Lung Sound Recordings

Observational SonoHL · NCT07464444

This project will try a wearable HALD vest that records heart and lung sounds during routine cardiology visits for adults with or without cardiopulmonary conditions.

What this trial studies

This is an observational effort to capture heart and lung sounds using the HALD investigational vest immediately after a standard clinic exam and ECG. Participants will wear a T-shirt and the HALD vest while recordings are made in several positions (lying and sitting) and with normal and deep breaths. Recordings will be automatically transferred to a computer, saved securely, and later compared to what the clinician heard during the physical exam. Participants must have had or be scheduled for an echocardiogram within 12 months so recordings can be interpreted in clinical context.

Who should consider this trial

Good fit: Adults (≥18 years) with a history of valvular heart disease, heart failure, pericarditis, coronary artery disease, other abnormal cardiopulmonary findings, or control participants with normal exams who can consent and have an echocardiogram within the prior or upcoming 12 months are ideal candidates.

Not a fit: People under 18, pregnant or lactating women, individuals with implantable electronic devices like pacemakers/ICDs, or those unable to give informed consent are excluded and would not benefit from participation.

Why it matters

Potential benefit: If successful, the HALD vest could provide reliable, standardized heart and lung sound recordings to support clinical exams and remote monitoring.

How similar studies have performed: Digital and wearable auscultation devices have shown promising results in prior work, but vest-style systems like HALD are relatively novel and still undergoing validation.
