Key result
Normalization of the cyclic variation of integrated backscatter in the myocardium (from 1.8 dB to 3.2 dB) preceded the recovery of left ventricular wall contractility in a patient with acute myocarditis.

Does ultrasonic tissue characterization predict recovery of cardiac function in acute myocarditis?
Normalization of cyclic variation of integrated backscatter preceded the recovery of left ventricular wall contractility, suggesting tissue characterization may predict functional recovery in acute myocarditis.
May support tissue characterization to predict myocarditis recovery; hypothesis-generating from single case, needs prospective validation.
A 25-year-old woman was admitted because of acute myocarditis. Echocardiogram revealed hypokinesis of the left ventricle with increased wall thickness, but on day 7, the wall motion normalized. Cyclic variation of myocardial integrated backscatter on day I was reduced to 1.8 dB (normal range, 2.9-5.3 dB) and normalized to 3.2 dB on day 3. The normalization of the cyclic variation of integrated backscatter in the myocardium preceded the recovery of the left ventricular wall contractility, suggesting the ability of tissue characterization to predict recovery of cardiac function.

Omi et al. (2002) conducted a case report in Acute myocarditis (n=1). Echocardiographic integrated backscatter (IB) analysis was evaluated on Cyclic variation of myocardial integrated backscatter (CV-IB) and left ventricular wall contractility. Normalization of the cyclic variation of integrated backscatter in the myocardium (from 1.8 dB to 3.2 dB) preceded the recovery of left ventricular wall contractility in a patient with acute myocarditis.
