Understanding Your Echocardiogram Report

Not necessarily. An EF of 50% falls into the "mildly reduced" range by most guidelines, but heart failure is a clinical diagnosis that depends on symptoms, signs, and other investigations — not on ejection fraction alone. Many people have an EF in the 45–54% range without symptoms and without any functional impairment. What matters is the combination of the number and the rest of the clinical picture, including how you feel, what your history is, and what other measurements on the report look like. Only a clinician who knows your full situation can interpret an individual EF.

No. Trivial mitral regurgitation is a normal finding on almost every adult echo. Modern ultrasound equipment is sensitive enough to detect the tiny amount of backflow that occurs as healthy valves close, and reporting it does not mean anything is wrong. The same applies to trivial regurgitation of the tricuspid and pulmonary valves. Unless the report describes the regurgitation as mild, moderate, or severe, it is a physiological finding and does not need treatment or follow-up.

LVH stands for left ventricular hypertrophy — thickening of the left ventricular walls. "Concentric" means the thickening is even all the way around (as opposed to "eccentric" or focal thickening in one region). Mild concentric LVH is most commonly caused by long-standing high blood pressure — the left ventricle thickens in response to the extra workload of pumping against a higher pressure. It can also be seen in athletes, in some inherited conditions, and with age. Your clinician will interpret it in the context of your blood pressure history, any symptoms, and other findings on the report.

Systolic function is how well the heart contracts and pushes blood out — the classic "pumping strength" measurement, captured in ejection fraction. Diastolic function is how well the heart relaxes and fills between beats. Both are essential: a heart can pump strongly but fail to fill properly, or fill well but pump weakly. Heart failure can be caused by either problem. Heart failure with preserved ejection fraction (HFpEF) is increasingly recognised — the pumping function is normal but the filling function is impaired, so the heart still cannot meet the body’s needs.

A small pericardial effusion is a small collection of fluid in the sac that surrounds the heart. In many cases it is incidental — a common and often benign finding, particularly in women, after viral infections, or with inflammatory conditions. A small effusion without any haemodynamic effect usually needs monitoring rather than treatment. The clinical concern rises with larger effusions, with rapid accumulation, or with signs that the fluid is affecting the heart’s filling (tamponade). Your report’s conclusion should state whether the effusion is considered clinically significant in your case.

Echo imaging has limits, and a good reporter will be honest about them. Phrases like "cannot exclude", "limited views", "suboptimal windows", or "recommend confirmation with alternative imaging" mean the scan could not give a definitive answer to a particular question. This is not the sonographer being vague — it is them being accurate about what the images did and did not show. When you see this language, the recommendation usually points to a further test: contrast echo to improve image quality, TOE for more detailed valve assessment, or cardiac MRI for tissue characterisation.

Small variations between reports from different laboratories or different times are common and usually not clinically meaningful. Measurements can vary by a few percent between scans because of differences in the operator, the machine, the patient’s position, heart rate, and hydration. What matters is whether the trend is stable, improving, or worsening — not whether an individual number matches the previous one exactly. Your cardiologist will compare the reports and focus on meaningful changes rather than minor variations. If a finding has genuinely changed, the newer report will usually flag this in the conclusion.

Yes. Every Sonoworld echo report is written by a BSE-accredited consultant cardiac sonographer, and any unexpected or complex finding is reviewed with a consultant cardiologist before the report is issued — at no extra cost. If you would like a separate face-to-face cardiology consultation to discuss your report, that can be arranged as an additional service. Call the clinic on 020 3633 4902 to discuss the options.

Breathlessness has many possible causes, and not all of them are cardiac. Within cardiac causes, a normal ejection fraction does not rule out heart failure: heart failure with preserved ejection fraction (HFpEF) is a real condition where the pumping function is normal but the filling is impaired. In that case, measurements like E/e’ ratio and left atrial volume index on your report are what to look at. Non-cardiac causes include lung disease, anaemia, deconditioning, thyroid problems, and anxiety. If the echo is normal but you still feel unwell, discuss the symptoms with your GP — the next step is often a focused review rather than a repeat echo.

"Hyperdynamic" means the left ventricle is contracting more vigorously than normal — an EF above about 70%. In many situations it is a temporary response to something physiological — being anxious on the couch, mild dehydration, anaemia, thyroid overactivity, or simply being a young, fit person. In other situations it can reflect hypertrophic cardiomyopathy or systemic conditions like sepsis. An isolated hyperdynamic finding in an otherwise well person with no symptoms is usually not a cause for concern, but it is worth discussing with your clinician so that any underlying cause can be excluded.
