Overview
Echocardiography in patients with myocarditis allows for serial assessment of left ventricular dysfunction, and can be used to distinguish fulminant (non-dilated hypocontractile left ventricle with thick interventricular septum) from acute myocarditis (dilated hypocontractile left ventricle with normal interventricular septum).[1]
Echocardiography
Cardiac function may be monitored via serial echocardiograms. In general, left ventricular function improves in fulminant myocarditis over a course of approximately 6 months. Echocardiographic findings in myocardits include:[1][2][3][4]
- Wall motion abnormalities
- Systolic dysfunction
- Diastolic dysfunction
- Changes in image texture on echocardiogram, i.e. increase in brightness, heterogeneity, and contrast
- Pericardial effusion may be noted in few patients
- Functional regurgitation through the AV valves may be noted due to ventricular dilation
Fulminant Versus Acute Myocarditis on Echocardiography
Fulminant myocarditis appears as a non-dilated, thickened and hypocontractile left ventricle with increased septal thickness while, acute myocarditis is associated with marked left ventricular dilation, normal septal thickness and decreased ventricular function.[1]
