Reading Your Echocardiogram Report Without a Cardiologist Handy

8 September 2026 · 3 min read

An echocardiogram (echo) report is dense with numbers, abbreviations, and jargon most patients receive without explanation. The cardiologist orders it, glances at the summary line, and moves on. The patient goes home with a report they cannot read but is afraid to throw away. Understanding the four or five values that matter turns the report into a document you can actually use.

The values that matter most

  • Field: Ejection fraction (EF) · What it means: % of blood pumped out per beat · Normal / concerning: 55-70% normal; < 40% is heart failure
  • Field: Left ventricular internal diameter (LVIDd) · What it means: Chamber size at rest · Normal / concerning: < 5.6 cm normal; larger suggests dilation
  • Field: Interventricular septum thickness (IVSd) · What it means: Wall thickness · Normal / concerning: < 1.1 cm normal; thicker = hypertrophy
  • Field: Left atrial size (LA) · What it means: Antechamber · Normal / concerning: < 4.0 cm normal; larger suggests chronic pressure
  • Field: Mitral / aortic valve gradient · What it means: Pressure across valves · Normal / concerning: Depends on which valve; specialist reads
  • Field: Regurgitation grade · What it means: Backflow through valves · Normal / concerning: Trivial to trace — usually normal; moderate+ matters

The summary line — where to look first

Every echo report ends with an impression paragraph. The specific phrases to notice:

  • 'Normal LV systolic function' — the heart pumps well.
  • 'Mild concentric hypertrophy' — often BP-related; not immediately concerning but a signal.
  • 'Dilated LV' — chamber is bigger than normal; needs specialist follow-up.
  • 'Reduced EF' or 'systolic dysfunction' — pumping is impaired; heart failure workup needed.
  • 'Regional wall motion abnormality' — a specific area moves poorly; suggests past or ongoing ischaemia.
  • 'Trace / mild regurgitation' — usually normal, especially in older adults.
  • 'Pericardial effusion' — fluid around heart; small ones common, large ones matter.

What NOT to worry about

  • 'Trace mitral regurgitation' — extremely common, usually meaningless.
  • 'Trivial pericardial effusion' — often incidental.
  • 'Aortic root at upper limit of normal' — worth watching, not treating.
  • 'PFO' or 'patent foramen ovale' — a normal fetal opening that persists in ~25% of adults; usually incidental.

Ejection fraction in detail

EF is the single most-quoted echo number. 55-70% is normal. 45-54% is borderline. 40-45% is mildly reduced. < 40% is heart failure with reduced EF. The measurement has an inter-reader variability of ±5%, so 52% one year and 48% next year is not a change — trend across multiple echoes matters.

What to keep in the record

  • The full report as PDF.
  • The key numbers extracted into a trend view.
  • The date and the reason the echo was done.
  • Any specific finding to watch (mild regurgitation trend, LV size trend).
  • The cardiologist's plan going forward.

A person with two echoes 5 years apart, both showing EF 55% and no other change, has objective evidence of stable cardiac status. That is worth more than a paragraph of general reassurance.
