"Try Pulling My Aorta" is a very popular way to remember the correct order of the four heart valves as blood flows through the heart:
❤️ This mnemonic helps you remember the sequence of the valves in the direction of blood flow:

Try – Tricuspid Valve
Separates the Right Atrium from the Right Ventricle.

Pulling – Pulmonary Valve
Separates the Right Ventricle from the Pulmonary Artery (blood going to the lungs).

My – Mitral Valve (Bicuspid)
Separates the Left Atrium from the Left Ventricle.

Aorta – Aortic Valve
Separates the Left Ventricle from the Aorta (blood going to the body).

Clear understanding of valve order and blood flow pathways is essential for interpreting cardiac physiology, murmurs, and pathology. Mnemonics like this transform memorization into true comprehension.
🫀 Better knowledge leads to better care.

🫀The heart is located within a special two-layered membrane known as the pericardium (cardiac sac). Between the inner (visceral) and outer (parietal) layers, there is normally a small amount of fluid (about 15–50 ml). This fluid acts as a lubricant, allowing smooth gliding of the pericardial layers during heart contractions and protecting the heart from excessive friction.

📝Pericardial effusion is the pathological, excessive accumulation of fluid in the pericardial cavity.
The increased volume of fluid creates external pressure on the heart, restricting diastolic filling of the ventricles. As a result, end-diastolic volume decreases, leading to a reduction in cardiac output.
Clinical manifestations may include shortness of breath, cough, and chest discomfort or pain of a pressing or bursting nature. The pain can worsen with coughing, deep breathing, movement, or lying on the back, and often improves when sitting and leaning forward. Other common symptoms include ▪️weakness,
▪️fatigue,
▪️and a sensation of breathlessness.

Rapid or massive accumulation of fluid can lead to cardiac tamponade – a life-threatening condition in which the cardiac chambers are critically compressed, potentially resulting in cardiogenic shock. This requires urgent treatment through pericardiocentesis.

During auscultation, muffled or diminished heart sounds may be heard, as the accumulated fluid acts as an acoustic barrier and impairs sound transmission.

☝By analyzing heart sounds, a physician can detect concerning signs and establish a preliminary diagnosis even before performing instrumental studies, particularly echocardiography (cardiac ultrasound).

Any heart murmur we hear can become a key to detecting serious health problems.

The identification and analysis of heart murmurs can reveal valvular dysfunction, congenital or acquired heart defects, structural abnormalities, and more. These issues are often caught at early stages, when treatment is most effective and patient outcomes can be significantly improved.

👂Every murmur has its own signature: timbre, frequency, intensity, point of maximal intensity (PMI), and timing within the cardiac cycle (systolic or diastolic).�With AI-enhanced phonoscopy using Stethophone, clinicians can analyze these features quickly and accurately. One murmur may suggest valve stenosis, another may indicate valve regurgitation, each linked to a specific valve or structure.

📝 Tracking Changes Over Time�
For patients with known heart conditions, regular auscultation helps monitor progress. It shows whether a condition is stabilizing, improving, or worsening and helps assess the response to treatment.

🫀 A Tool in the Doctor’s Hands�
Even though modern medicine offers highly accurate tools such as MRI, CT, and echocardiography, phonoscopy remains one of the earliest and most accessible diagnostic methods. It serves as a fast-screening tool that guides whether more advanced testing is needed. The physician’s ability to interpret cardiac sounds correctly is a skill that can truly save lives.

When evaluating a heart murmur, clinicians systematically assess several characteristics to help determine its cause and significance. Heart sound analysis isn’t just about noticing a sound, it’s about characterizing every detail.

Know the 6 essential characteristics you MUST evaluate for every heart murmur.

📝 A frequent finding in children, but sometimes this kind of murmur can be present in adults.
☝Valvular aortic stenosis can be erroneously classified as a Still’s murmur.
🧐Aortic stenosis murmurs have a longer duration and contain higher frequency vibrations.

🎧 The Levine Scale is a classic system for grading the intensity of heart murmurs, ranging from 1/6 to 6/6.
Developed by cardiologist Samuel Levine in 1933, it remains the gold standard in international cardiology practice.

Knowing and using this scale:
- Simplifies communication with international colleagues
- Is essential for certification and standardized reporting
- Is referenced in all major global guidelines
It’s a simple yet powerful tool that helps standardize auscultation, support diagnostic reasoning, and improve communication among clinicians — a fundamental skill every practitioner should master.

📝How to Document Findings
✅ Correct: “Systolic murmur 4/6 at the aortic area, radiating to the carotids, with palpable thrill.”
❌ Incorrect: “Loud heart murmur.”

⚠️ Important Nuances
Intensity ≠ Severity
A soft diastolic murmur (2/6) may signal severe aortic regurgitation.
A loud systolic murmur (4/6) can be innocent in a child.

Always assess:
✅ Timing: systolic or diastolic
✅ Location & radiation
✅ Character: harsh, musical, blowing, decrescendo, etc.
✅ Associated symptoms: dyspnea, chest pain, syncope, edema

Takeaway:
The Levine Scale remains a timeless clinical language — a simple, universal code that bridges generations and borders in cardiology.

Had an inspiring experience at the Scientific Sessions 2025 in New Orleans.

It was a privilege to engage with innovators and thought leaders shaping the future of cardiovascular care at the Health Innovation Pavilion.

A huge thank-you to the American Heart Association for organizing such a meaningful event, and to the Health Innovation Pavilion team for creating a space where science, technology, and care truly come together.

Special thanks to Mark Attila Opauszky, CEO of Sparrow BioAcoustics, for sharing valuable insights on device-agnostic AI and demonstrating Stethophone.

Appreciative of every conversation, new connection, and shared heartbeat that made this event truly memorable.

The era when ANOCA (Angina with Non-Obstructive Coronary Arteries), INOCA (Ischemia with Non-Obstructive Coronary Arteries), and MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) were considered mere “diagnoses of exclusion” is over.

Contemporary cardiology now recognizes them as distinct clinical entities, each with specific pathophysiological mechanisms, microvascular dysfunction, vasospasm, or plaque disruption, requiring targeted evaluation and management.
The key is not a generic approach, but a mechanism-driven workup using functional coronary testing or advanced imaging to clarify the underlying cause and guide tailored therapy.
