The next test after an abnormal echocardiogram depends on what the scan showed and whether you have symptoms. Your clinician may review the images, repeat the ultrasound, or order an ECG, stress test, cardiac MRI, CT scan, blood tests, or a procedure that measures heart pressures. Some findings only need monitoring; others need prompt specialist review. Ask what the result means and when follow-up should happen.
An echocardiogram, often called an echo, uses sound waves to create pictures of the heart. It helps clinicians assess the heart's pumping action, chambers, valves, and blood flow. An unexpected finding does not automatically mean that you have a serious heart condition or need another test immediately. The next step depends on the specific finding, the quality of the images, your medical history, and any symptoms you have.
What happens first after an abnormal echocardiogram?
The first step is usually to review the complete echocardiogram report with the healthcare professional who requested the test. They may explain which part of the heart looked different, whether the finding was expected, and whether it needs further investigation. The clinician may also compare the result with an earlier echocardiogram to see whether anything has changed.
According to the American Heart Association, an echocardiogram can provide information about heart size, pumping strength, valve function, blood flow, and other structural features. The particular abnormality helps determine which additional test, if any, would be useful.
For example, a report describing a valve that does not open fully may lead to further assessment of the valve. A finding involving the heart's pumping function may prompt additional tests to understand how well the heart works. If the images did not show the structures clearly, the clinician may recommend obtaining better pictures rather than moving directly to an unrelated test.
Which test may be recommended next?
There is no single test that follows every abnormal echocardiogram. The following investigations serve different purposes, and a healthcare professional selects among them according to the information still needed.
1. A repeat echocardiogram
A repeat echo may be appropriate when the original images were unclear, the measurements need confirmation, or the clinician needs to check a known finding over time. It uses the same general ultrasound method and can help establish whether the finding remains similar or has changed.
Sometimes the clinician can obtain the necessary information by repeating the standard scan, adjusting the imaging approach, or using an ultrasound contrast agent to make certain heart structures easier to see. Whether another scan is necessary depends on how much useful information the first study provided.
2. A transesophageal echocardiogram (TEE)
A transesophageal echocardiogram creates detailed pictures by placing a thin ultrasound probe into the esophagus, the tube connecting the mouth to the stomach. Because the esophagus lies close to the heart, this approach can show some heart structures more clearly than a standard scan performed through the chest.
Mayo Clinic explains that a TEE may be recommended when a standard echocardiogram does not provide enough detail. It may help clinicians examine heart valves, the aorta, or other structures that require a closer view.
The procedure generally involves throat numbing and medication to help the patient relax. Preparation instructions vary, and patients are usually told whether they must avoid food and drink beforehand. The healthcare team explains the procedure, its potential risks, and any precautions relevant to the individual's health.
3. An electrocardiogram (ECG or EKG)
An ECG records the heart's electrical activity. Unlike an echocardiogram, which produces pictures of the heart, an ECG helps assess the timing and pattern of the heartbeat. A clinician may request one when the echo finding needs to be considered alongside the heart's rhythm or electrical activity.
An ECG is commonly combined with other investigations when someone has symptoms such as palpitations, dizziness, or unexplained breathlessness. If an intermittent rhythm problem is suspected, a longer period of heart-rhythm monitoring may sometimes provide information that a brief ECG cannot capture.
4. An exercise stress test or stress echocardiogram
A stress test examines how the heart responds when the body is working harder. Depending on the test, the patient may walk on a treadmill, pedal a stationary bicycle, or receive medicine that increases the heart's workload when exercise is not suitable.
A stress echocardiogram adds ultrasound images taken before and during or after the increased workload. This can help clinicians investigate concerns about blood supply to the heart muscle or understand certain heart-valve problems when symptoms during activity are difficult to assess.
The American Heart Association's guide to heart valve testing describes how exercise testing can be used with other investigations to evaluate symptoms, changes in blood pressure, and exercise capacity. A stress test is not automatically required after an abnormal resting echocardiogram; the decision depends on the clinical question.
5. A cardiac MRI
Cardiac magnetic resonance imaging, commonly called cardiac MRI, uses a magnetic field and radio waves to create detailed pictures of the heart. It may be useful when clinicians need more information about the heart muscle, the size and function of its chambers, or certain structural abnormalities that were not fully explained by ultrasound.
The American Heart Association notes that cardiac MRI can help evaluate complex heart conditions and is often requested after other tests have been performed. The need for MRI depends on what remains uncertain after the original scan.
Before the examination, patients should tell the imaging team about implanted devices, metal in the body, kidney problems, or other relevant medical circumstances. The team will determine whether MRI is appropriate and whether any special preparation is needed.
6. A cardiac CT scan or coronary angiography
A cardiac CT scan uses X-rays to create detailed images of the heart and nearby structures. It may be considered when an echocardiogram does not provide enough information about certain valves, anatomy, or related structures. A CT coronary angiogram is a more specific examination that uses contrast material to produce images of the arteries supplying the heart.
A standard echocardiogram does not directly show whether a coronary artery is blocked. When reduced blood flow to the heart is a concern, clinicians may consider a stress test, CT coronary angiography, or an invasive coronary angiogram, depending on the circumstances. These investigations answer different questions and are not interchangeable.
In an invasive coronary angiogram, a thin tube is guided through a blood vessel and contrast material is used to make the coronary arteries visible on X-ray images. It may be recommended when the clinical assessment suggests that direct examination of the coronary arteries is needed.
7. Blood tests, a chest X-ray, or cardiac catheterization
Additional tests may complement the echocardiogram when the clinician needs to assess symptoms or investigate other aspects of heart function. Blood tests may include measurements related to kidney function, electrolytes, or substances released in response to strain on the heart. A chest X-ray can provide information about the heart's overall size and the lungs, but it cannot replace an echocardiogram.
The American Heart Association's information on heart failure testing describes how blood tests, ECGs, chest X-rays, and echocardiography can contribute different information to a clinical assessment. Not everyone with an abnormal echo needs all these tests.
Cardiac catheterization may also be considered when clinicians need to measure pressures inside the heart or lungs, assess blood flow, or clarify findings that remain uncertain after noninvasive testing. It is an invasive procedure, so the decision depends on whether the additional information is likely to help guide care.
Does an abnormal echocardiogram always require another test?
No. Some findings need no additional investigation beyond a review of the report and routine follow-up. Others require a repeat scan at an appropriate interval or a more detailed examination. The word "abnormal" describes a result that differs from what is expected; it does not, by itself, explain its importance or determine what treatment is needed.
The clinician considers the exact finding, whether it was adequately measured, symptoms, existing medical conditions, previous test results, and relevant examination findings. A result that needs monitoring may have a different follow-up plan from one that suggests an important change in heart function or a structural problem requiring specialist assessment.
When should you seek medical attention?
Follow the instructions provided with your results, particularly if your clinician has requested prompt specialist review. Contact your healthcare professional if you have new or worsening breathlessness, reduced ability to carry out usual activities, persistent palpitations, or episodes of dizziness or fainting.
Seek emergency medical care for chest pain or pressure that may indicate a heart attack, severe difficulty breathing, collapse, or other sudden, serious symptoms. Do not wait for a scheduled echocardiogram review if you think you may be experiencing a medical emergency.
How can you prepare for the follow-up appointment?
Bring a copy of the echocardiogram report if it is available, along with previous heart-test results and an up-to-date list of medicines and supplements. Describe any symptoms, when they occur, and whether they have changed. This information helps the clinician place the imaging findings in context.
It is also useful to ask which part of the echocardiogram was abnormal, what the proposed next test is meant to clarify, how soon it should be completed, and whether any preparation is required. Ask when you should expect the results and who will explain them to you.
What determines the final follow-up plan?
The next step is chosen to answer a specific clinical question, not simply because the report contains an unexpected result. Some people need only a discussion and planned monitoring. Others may need clearer images, assessment during exercise, a different type of heart scan, or a specialist consultation.
Once the additional information is available, the healthcare professional can explain what it means for your care. Depending on the findings, the plan may involve continued observation, further investigation, medication, or referral to a cardiologist or another specialist.
