Overview
Echocardiography in patients with myocarditis allows for serial assessment of left ventricular dysfunction. Echocardiography is helpful in differentiating acute from fulminant myocarditis[1].
Echocardiography
Echocardiographic findings in myocardits include:
- Wall motion abnormalities[2].
- Systolic dysfunction[2][3].
- Diastolic dysfunction[4].
- Changes in image texture on echocardiogram, i.e. increase in brightness, heterogeneity, and contrast[5].
- Fulminant myocarditis appear as nondilated, thickened and hypocontractile left ventricle with increased septal thickness. While, those with acute myocarditis have a marked left ventricular dilation, normal septal thickness and decreased ventricular function[1].
- Pericardial effusion may be noted in few patients.
- Functional regurgitation through the AV valves may be noted in patients with dilated ventricles.
- Cardiac function may be monitored over a period. And it is found to improve in fulminant myocarditis over approximately 6 months[1].
