How to hear Barlow's disease (BD)?

For a long time, Barlow's disease remains asymptomatic, but this pathology can be suspected with Stethophone much earlier. ☝️

Barlow's disease is a degenerative lesion of the heart valve apparatus. The mitral valve (MV) is most commonly affected (less frequently other valves). It is characterized by myxomatous thickening of the MV leaflets and their prolapse into the left atrium. ↩️

True Barlow's disease accounts for about 5–10% of all mitral valve prolapse cases, primarily affecting young people.

Why is timely detection so important? 👉 Because Barlow's disease can carry serious risks for the patient:

🔴 Sudden cardiac death (SCD): accounts for 2% of SCD cases among adults.

🔴 Progression of mitral regurgitation to a severe stage.

🔴 Infective endocarditis: the risk is 3–5 times higher than in the healthy population.

🔴 Risk of arrhythmia: ventricular tachycardia, atrial fibrillation.

Diagnostics: AI-phonoscopy with Stethophone 🎧☝️:

Systolic click/clicks in the mid or late systolic phase.

Late systolic murmur (see the sound recording video case above ⬆️).

ECG: changes are non-specific.

Echocardiography: (see the video above ⬆️).

As a regulated Software as a Medical Device platform, Stethophone Pro is designed to extend cardiovascular detection infrastructure directly into upstream patient encounters. By integrating AI phonoscopy and bioacoustic analysis into everyday clinical flows, such as primary care, urgent care, and hospital intake, cardiac findings are captured early in the care pathway. These findings then become visible, actionable triage signals for cardiology and structural heart programs

By identifying appropriate patients earlier and directing them efficiently into existing care pathways, health systems can achieve:
🔹️Increased Program Yield: Delivering validated referrals, high-yield imaging, and timely valve interventions
🔹️Structured Triage: Optimizing cardiovascular care routing and initial diagnostic cascades (like Echo and CT Angiography)
🔹️Improved Program Outcomes: Driving earlier interventions, lower mortality, better care coordination, and fewer emergency admissions

⚕️Stethophone Pro helps health systems unlock latent demand within their own networks and capture clinical value that would otherwise be missed.

🩺 National Nurses Week in the United States is observed each year from May 6–12, culminating on the birthday of Florence Nightingale, whose contributions helped shape nursing into a structured, patient-centered clinical profession grounded in observation and organization.

Today, nurses play a vital role across the full continuum of care—from assessment and monitoring to coordination, education, and long-term support. Their work strengthens not only patient outcomes but the overall effectiveness of healthcare systems.

🤍 This week, we recognize and sincerely appreciate the expertise, dedication, and clinical judgment nurses bring to every setting they serve.

From all of us at Sparrow BioAcoustics and the Stethophone Pro team, thank you for the care, resilience, and compassion you bring to patients every day. We deeply value the work you do and remain committed to supporting healthcare professionals with tools designed to enhance care delivery, improve patient monitoring, and enable earlier detection across the healthcare system.
Thank you for the essential work you do every day!

One of the biggest challenges in cardiology diagnostics is finding the right patients on time. 🫀 While most current solutions focus on downstream imaging or EMR recognition, they leave the initial referral cohort completely unchanged. The result? Late-stage, complex, and high-cost cases continue to dominate the system.

Stethophone Pro changes this by moving detection upstream. By integrating into routine, non-cardiac encounters, we help shift the patient mix before referral decisions are even made.

Swipe through to see how small upstream shifts lead to earlier identification, more precise referrals, and a dramatically more efficient healthcare system. ➡️✨

The mitral valve regulates blood flow from the left atrium to the left ventricle. When its function is impaired, characteristic acoustic patterns can be identified.

1. Mitral Regurgitation (Insufficiency)

Occurs when the valve leaflets (anterior or posterior) fail to achieve complete coaptation, allowing blood to flow backward into the left atrium during systole.

Clinical acoustic finding:
A systolic murmur, typically holosystolic (pansystolic), with a blowing quality.

Point of evaluation:
Best perceived at the cardiac apex (5th intercostal space along the left midclavicular line).

Radiation: The acoustic pattern often extends toward the left axilla.

2. Mitral Stenosis

Characterized by narrowing of the valve or***ce due to leaflet thickening, fusion, or annular fibrosis, leading to impaired left ventricular filling.

Clinical acoustic findings:
Mitral stenosis produces diastolic low-frequency acoustic patterns, typically including:

A mid-diastolic rumble

A late diastolic accentuation (presystolic) in the presence of coordinated atrial contraction

Additional signs:

An opening snap (OS) following S2

Increased intensity of the pulmonary component of S2, reflecting elevated pulmonary pressures

☝️Note: In the presence of atrial fibrillation, atrial contraction is absent; therefore, presystolic accentuation is not present.

3. Mitral Valve Prolapse (MVP)

Occurs when one or both mitral leaflets (more commonly the posterior leaflet) displace into the left atrium during ventricular contraction.

Clinical acoustic finding:
A characteristic mid-systolic click, often followed by a late systolic murmur, reflecting tension on the valve apparatus and variable regurgitant flow.

📑Why is this clinically relevant?

The subvalvular apparatus — particularly the chordae tendineae and papillary muscles — plays a critical role in valve competence.

For example, chordae tendineae rupture can result in acute mitral regurgitation, generating an intense and often complex systolic acoustic pattern due to abrupt hemodynamic changes and turbulent flow.

Bicuspid Aortic Valve (BAV): How Leaflet Fusion Types Define Patient Risks

A characteristic auscultatory pattern of BAV is present in 60-70% of cases. Most patients with BAV eventually develop a combination of aortic stenosis and regurgitation. Based on the type of aortic valve leaflet fusion, it is possible to partially predict which valvular defect will predominate—stenosis or regurgitation.

BAV Morphological Phenotypes according to Sievers:

1️⃣ RL-type (70-80% of cases) – fusion of the Right (R) and Left (L) coronary leaflets. Aortic stenosis develops more frequently due to constant trauma and accelerated calcification of the fusion site (raphe). Stenosis manifests at least 10-15 years earlier than in a tricuspid aortic valve. It is often associated with coarctation of the aorta (especially in children) and aortic root dilation at the level of the sinuses of Valsalva. It is more common among men.

2️⃣ RN-type (20-30% of cases) – fusion of the Right (R) and Non-coronary (N) leaflets. Aortic regurgitation develops more frequently: disruption of the annular geometry and an often longer free edge of the leaflet lead to prolapse and incomplete closure. There is a higher risk of progressive aortopathy, including dilation and aneurysm of the ascending aorta, and a higher risk of aortic dissection at a young age.

3️⃣ LN-type (3-6% of cases) – fusion of the Left (L) and Non-coronary (N) leaflets. The rarest phenotype, which often follows a clinical course similar to the RN-type and requires differential diagnosis with rheumatic heart disease. (See the normal aortic valve leaflet arrangement in the image above: parasternal short-axis view at the AV level, PSAX).

🦠 All patients with BAV are in a high-risk group for developing infective endocarditis.

📈 When BAV is detected, an Echocardiographic (EchoCG) assessment of not only the valve but also the aortic diameters at all levels is mandatory.

🔹 BAV can be hereditary; therefore, screening EchoCG is recommended for first-degree relatives.

Severe Mitral Regurgitation due to Chordae Tendineae Rupture📝

A flail segment of the anterior mitral valve leaflet can be seen prolapsing into the left atrium, associated with a significant regurgitant jet. In acute settings, this condition is frequently accompanied by pulmonary edema due to a rapid rise in left atrial pressure.

From a clinical perspective, this presentation generates a characteristic systolic acoustic pattern.

A clinician may perceive an acute mitral regurgitation murmur, typically a loud holosystolic (pansystolic) murmur. In acute cases, however, the murmur may demonstrate a decrescendo profile, with greater intensity in early to mid-systole and reduced intensity toward late systole, reflecting rapid pressure equalization between the left ventricle and left atrium.

A systolic thrill may be present in cases of significant turbulent flow.

Emergency departments rely on structured triage systems to rapidly assess patient acuity and allocate clinical resources. One of the most widely used frameworks is the Emergency Severity Index (ESI), a five-level triage algorithm that helps clinicians prioritize care based on patient stability and anticipated resource needs.

From Level 1 (Immediate) cases such as cardiac arrest or profound hypotension, to Level 5 (Non-Urgent) presentations requiring minimal intervention, ESI provides a standardized pathway for decision-making in high-pressure clinical environments.

Because certain cardiac abnormalities may produce acoustic signals before imaging confirmation, structured triage combined with early heart sound analysis tools can support clinicians in identifying patients who may require earlier escalation in the care pathway.

Understanding how triage systems function is essential for improving patient flow, resource allocation, and timely cardiac evaluation.
