What does dilated cardiomyopathy look like on Echo?

On a four-chamber view the ventricle will show a “hula hoop” or rocking motion. Dilated cardiomyopathy in a patient with a very wide (180 ms) left bundle branch block (LBBB) and distinct dyssynchrony. The ventricle shows rocking motion.

Can you see dilated cardiomyopathy on Echo?

Echocardiography has crucial importance in the diagnosis of dilated cardiomyopathy (DCM). Echocardiographic features of DCM are left ventricular (LV) dilation and systolic dysfunction with impaired global contractility and normal LV wall thickness and LV diastolic dysfunction with elevation in LV filling pressure.

Can an echocardiogram detect hypertrophic cardiomyopathy?

Echocardiogram. An echocardiogram is commonly used to diagnose hypertrophic cardiomyopathy. This test uses sound waves (ultrasound) to see if your heart’s muscle is abnormally thick. It also shows how well your heart’s chambers and valves are pumping blood.

Is there hypertrophy in dilated cardiomyopathy?

Dilated cardiomyopathy is characterized by ventricular chamber enlargement and systolic dysfunction with greater left ventricular (LV) cavity size with little or no wall hypertrophy.

How is dilated cardiomyopathy diagnosed?

Tests to diagnose dilated cardiomyopathy include:

  1. Echocardiogram. This is the main test for diagnosing dilated cardiomyopathy.
  2. Blood tests.
  3. Chest X-ray.
  4. Electrocardiogram (ECG or EKG).
  5. Holter monitor.
  6. Exercise stress test.
  7. Heart (cardiac) CT or MRI scan.
  8. Cardiac catheterization.

How do you assess dilated cardiomyopathy?

2.2. Echocardiography is the first-line imaging test in the assessment of patients with DCM. It provides pivotal information not only for diagnosis, risk stratification and guiding treatment, but also plays a key role in screening family members.

How do you diagnose hypertrophy?


  1. Electrocardiogram (ECG or EKG). Electrical signals are recorded as they travel through your heart.
  2. Echocardiogram. Sound waves produce live-action images of your heart.
  3. MRI. Images of your heart can be used to diagnose left ventricular hypertrophy.

How can you tell the difference between dilated and hypertrophic cardiomyopathy?

The most common types of cardiomyopathy are:

  1. Dilated cardiomyopathy: Your heart’s blood-pumping chambers enlarge (dilate).
  2. Hypertrophic cardiomyopathy: Your heart muscle thickens.
  3. Arrhythmogenic right ventricular dysplasia (ARVD): Disease in your heart muscle causes irregular heart rhythms.

What is the difference between hypertrophic cardiomyopathy and dilated cardiomyopathy?

In most cases of dilated cardiomyopathy, the cause is unknown. HCM occurs because the heart’s walls become thickened, which makes it harder for the heart to pump blood. In obstructive hypertrophic cardiomyopathy the ventricle size remains normal, but thickening of the walls may block blood flow out of the ventricles.

What 2 things must be present to diagnose dilated cardiomyopathy?

Diagnosis and Tests DCM is diagnosed based on your medical history, physical exam, and other tests. Specific tests may include blood tests, electrocardiogram (ECG), chest X-ray, echocardiogram, exercise stress test, cardiac catheterization, CT scan, MRI scan, and radionuclide studies.

What assessment findings would suggest hypertrophic cardiomyopathy?

The most common presenting symptom of hypertrophic cardiomyopathy is dyspnea. Patients also can develop syncope, palpitations, angina, orthopnea, paroxysmal nocturnal dyspnea, dizziness, congestive heart failure, and sudden cardiac death. The latter represents the most devastating presenting symptom.

What is the difference between dilated cardiomyopathy and cardiomyopathy?

Cardiomyopathies are diseases of the myocardium associated with cardiac dysfunction, often resulting in the clinical syndrome of heart failure. Dilated cardiomyopathy is defined as an ejection fraction of lower than 40% in the presence of increased left ventricular dimensions.
