Overview
Echocardiography is the most common imaging finding used to diagnose dilated cardiomyopathy. Findings may include ventricular and atrial dilatation, increased left ventricular mass, a global reduction in systolic function, and focal wall motion abnormalities.
Echocardiography/Ultrasound
Echocardiography
The diagnosis of dilated cardiomyopathy is based on clinical presentation and imaging findings. The most common imaging modality used to diagnose dilated cardiomyopathy is 2D-echocardiography. Echocardiographic findings of dilated cardiomyopathy include:
- Dilation of the left ventricle; however, may include dilatation of all 4 cardiac chambers
- LV (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[1]
The diagnosis requires a dilated left ventricle and low ejection fraction.
