Echo Fact of the Day
B-lines on Lung Ultrasound
Multiple vertical B-lines suggest interstitial syndrome (e.g., pulmonary edema).
💡 Why?
Thickened interlobular septa and fluid-filled alveoli create reverberation artifacts seen as B-lines.
Common causes:
Heart failure
ARDS
Pulmonary fibrosis
📷 Pro Tip:
Diffuse bilateral B-lines → think cardiogenic edema
Focal B-lines → think pneumonia

🩺 Echo Fact of the Day
On parasternal short-axis view at the papillary muscle level, a D-shaped left ventricle suggests right ventricular pressure overload.

💡 Why?
Increased RV pressure pushes the interventricular septum toward the LV during systole, flattening it and creating the “D” configuration.
Common causes include:

Pulmonary hypertension

Pulmonary embolism

Severe pulmonary valve stenosis

📷 Pro Tip: Always check both systolic and diastolic frames—septal flattening in diastole may indicate RV volume overload instead.

🩺 Echo Insight: E/e′ Ratio

What is it?
Ratio of mitral E velocity to mitral annular e′ (TDI).

Why it matters:
👉 Estimates LV filling pressures

Cut-offs:
• E/e′ 14 → Elevated filling pressures
• 8–14 → Indeterminate (needs more parameters)

💡 Take-home:
E/e′ is one of the most practical bedside tools for diastolic assessment

what diagnosis

04/05/2026

💎Higher PHT
Reduced Slope
Lower Mitral Valve Area (more stenosed)

💎Lower PHT
