Quick answer: An echocardiogram is an ultrasound of your heart. The headline number is the ejection fraction (EF) — the percentage of blood the main pumping chamber ejects each beat; roughly 50-70% is normal. The report also grades each valve (trace/mild/moderate/severe leaks or narrowing), chamber sizes, and wall motion. “Trivial” and “mild” findings are extremely common and often normal wear — the grading word matters more than the finding itself.
Echo reports terrify patients because normal hearts generate abnormal-sounding sentences: “trivial mitral regurgitation,” “mild diastolic dysfunction,” “borderline LA dilation.” Much of this is the cardiac equivalent of grey hair. This guide decodes the structure of the report so you can tell routine wording from findings that actually drive decisions.

The Headline: Ejection Fraction
| EF | Meaning |
|---|---|
| 50-70% | Normal pump function |
| 41-49% | Mildly reduced / borderline |
| Below 40% | Reduced — the heart-failure treatment threshold |
| Above ~75% | Hyperdynamic — occasionally its own clue |
EF is the number that steers heart failure care, but it is an estimate with a margin of a few percent — a “change” from 55 to 52 is usually measurement noise, not deterioration. Trends across studies on the same machine mean more than single values. A normal EF with symptoms can still be heart failure (the “preserved EF” type), which is why the BNP blood test and the rest of the report matter.

Decoding the Rest of the Report
- Valves: each is graded — trace/trivial and mild leaks (regurgitation) are common in healthy hearts and usually just watched; moderate gets surveillance echoes; severe drives intervention discussions
- Chamber sizes: “dilated” atria or ventricles reflect pressure or volume load over time — context for conditions like atrial fibrillation
- Wall motion: segments that move poorly can map to previous heart attacks or strain
- Diastolic function: how the heart relaxes and fills — “grade 1 diastolic dysfunction” is near-universal with age and usually not a disease label
- Pericardium and pressures: fluid around the heart and estimated lung-artery pressure round out the survey
Questions to Ask About Your Echo
- Is my EF normal — and has it changed from my last echo?
- Do any valve findings need follow-up, and on what schedule?
- Do the findings explain my symptoms — or do we need other tests?
- Does anything here change my medications or activity?
- When, if ever, should this be repeated?
Regional Notes
Singapore: Echoes are done at hospital cardiac labs and private cardiology clinics; subsidised rates need the referral pathway.
Australia: Medicare rebates apply with GP or specialist referral; reports go to the referrer — ask for your copy.
United States: Widely available; check pre-authorisation requirements, and request the report and images through your portal.
