What Your ECHO Report
Actually Means
A plain-English, science-backed guide to understanding what the echocardiogram machine sees — valves, muscle, walls — and what your doctor decides next.
What it is
Painless ultrasound that bounces sound waves off your heart to build live moving pictures
How long
30–60 minutes. No needles, no radiation. You lie still while a wand glides on your chest
Who reads it
A cardiac sonographer scans; a cardiologist reviews images and writes the final report
The Four Things ECHO Examines
Anatomical Map — What the Machine Sees
Mitral Valve
Tricuspid Valve
Aortic Valve
Pulmonary Valve
Wall / Muscle
Part 1 — The 4 Heart Valves
Think of your heart valves as one-way doors. They must open fully and seal completely. ECHO watches each door open and close in real time using colour-coded blood flow (Doppler).
🚪
Mitral Valve
Left Atrium → Left Ventricle
Stenosis: Door too narrow — heart labours to push blood through
Regurgitation: Door leaks — blood flows backward into atrium
Prolapse: Leaflet bulges back — common, often mild
🚪
Aortic Valve
Left Ventricle → Aorta → Body
Stenosis: Most common; often from calcium build-up with age
Regurgitation: Blood leaks back; heart works overtime
Calcification: Stiff, echogenic valve — may need replacement
🚪
Tricuspid Valve
Right Atrium → Right Ventricle
Regurgitation: Most common finding; mild TR is near-normal
RVSP: Pressure estimated from TR jet — screens for pulmonary hypertension
🚪
Pulmonary Valve
Right Ventricle → Lungs
Stenosis: Often congenital; restricts blood to lungs
Mild PR: Trace regurgitation is common and harmless
Part 2 — Heart Muscle (Ejection Fraction)
Ejection Fraction (EF) — The Pump Power Score
How much blood does the left ventricle eject with every single beat?

🏋️ Muscle Too Thick
LVH — Left Ventricular Hypertrophy
Wall thickness >12mm. The muscle has bulked up — usually from years of untreated high blood pressure or aortic stenosis. Like a bodybuilder's muscle that becomes stiff rather than strong.
👨⚕️ Doctor acts: Tighten BP control · Add ACE inhibitor · Repeat echo in 6 months
💔 Muscle Too Weak
Dilated Cardiomyopathy (DCM)
Ventricle is enlarged and flabby, EF below 40%. The pump stretches but can't squeeze properly. Can be from viral infections, alcohol, genetic causes or chronic ischemia.
👨⚕️ Doctor acts: Beta-blockers · Diuretics · ICD if EF <35% · Consider transplant listing
🧱 Muscle Too Stiff
Diastolic Dysfunction
EF is normal but the ventricle can't relax and fill properly between beats. Very common after 60. Causes breathlessness especially on exertion. ECHO's tissue Doppler (E/e' ratio) detects this.
👨⚕️ Doctor acts: Control BP and diabetes · Low-sodium diet · Spironolactone
Part 3 — Wall Motion (Segment by Segment)
The LV wall is divided into 17 segments. Each must squeeze inward during every heartbeat. ECHO grades how well each segment moves — this maps blocked arteries without a single needle.
Normokinesis
Normal Movement
Wall squeezes inward normally with every beat. Healthy blood supply confirmed.
Hypokinesis
Sluggish Movement
Wall moves, but weakly. Partial blockage — artery is narrowed but not fully closed.
Akinesis
No Movement
Segment is completely still. That area had a heart attack. Scar tissue has replaced muscle.
Dyskinesis
Paradoxical Bulge
Segment bulges outward when it should squeeze in — a ventricular aneurysm. Clot risk is high.
Pericardial Effusion
Fluid Around Heart
Dark halo of fluid visible around heart. If large, it can compress the heart — a medical emergency.
Wall Thickness
Measured in mm
Normal septum: 6–11mm. >15mm = hypertrophic cardiomyopathy — a hereditary thickening disorder.
What the Doctor Decides Next
ECHO Finding → Clinical Action Map
What each key finding triggers in a cardiologist's mind
| ECHO Finding | What It Means | Action |
|---|---|---|
| EF < 35% | Severe pump failure | ICD / CRT device |
| Severe Aortic Stenosis | Valve area <1 cm² with symptoms | TAVR / Surgery |
| Severe Mitral Regurgitation | Massive backflow, EF falling | Valve repair / replace |
| Wall Motion Abnormality | Blocked coronary artery | Angiogram → Stent |
| LVH (wall >13mm) | Hypertensive heart, stiff | Optimise BP drugs |
| Pericardial effusion >2cm | Fluid compressing heart | Urgent pericardiocentesis |
| RVSP >50 mmHg | Pulmonary hypertension | Right heart catheter |
| Dilated LA (>4.5cm) | Atrial fibrillation substrate | Anticoagulation |
Patients Always Ask…
Mild mitral regurgitation is extremely common — found in up to 10% of healthy adults. Doctors simply monitor it annually. Panic is unwarranted. Only moderate-to-severe MR with symptoms or falling EF requires intervention.
55% is at the lower end of normal (normal: 55–70%). It means your heart pumps 55 ml of every 100 ml of blood it receives. Absolutely fine — your doctor will likely just repeat the echo in a year.
Grade 1 (mild) diastolic dysfunction is very common after 55 and often related to age, blood pressure, or diabetes. It means the heart stiffens slightly. Lifestyle changes — less salt, controlled BP, regular walking — are the primary treatment. Not an emergency.
Not directly — but ECHO detects the consequence of a blocked artery: wall motion abnormality in the territory supplied by that vessel. A stress echo (during exercise) makes this much more sensitive. For definitive artery imaging, a coronary angiogram is needed.
Depends on findings. Normal ECHO with no symptoms: every 3–5 years if you're over 60 or have hypertension. Known valve disease: every 1–2 years. Severe valve disease or low EF: every 6–12 months or as advised. Never self-order repeat echos — let your cardiologist guide frequency.
