Overview
Dilated cardiomyopathy may be diagnosed on echocardiography if case of the presence of left ventricular dilatation and left ventricular systolic dysfunction in the absence of abnormal loading conditions (hypertension and valve disease) or coronary artery disease sufficient to cause global systolic impairment.
Diagnostic Study of Choice
Study of choice
Echocardiography is the gold standard test for the diagnosis of dilated cardiomyopathy.
Diagnostic Results
The following finding(s) on performing echocardiography are confirmatory for dilated cardiomyopathy.[1]
- Dilation of the left ventricle; however, may include dilatation of all 4 cardiac chambers
- Left ventricular wall thickness usually is normal but given the dilation the LV mass is increased
- In addition, there is a global reduction in systolic function
- Occasionally, there may also be focal wall motion abnormalities even in patients without flow limiting coronary artery disease
British Society of Echocardiography Criteria
According to the British Society of Echocardiography, dilated cardiomyopathy may be diagnosed on echocardiography in case of:
- The presence of left ventricular dilatation and left ventricular systolic dysfunction
- In the absence of abnormal loading conditions (hypertension and valve disease) or coronary artery disease sufficient to cause global systolic impairment.[2]
