Insights of prognostication of Davies disease: what could we learn from serial magnetic resonance imaging studies?

Davies disease (Hypereosinophilic syndrome with endomyocardial fibrosis) has been increasingly recognized with the availability of cardiac magnetic resonance imaging (CMR). The reported features identified include the thickened left ventricular (LV) apex and the presence of endomyocardial fibrosis and thrombus. However, CMR allows serial noninvasive monitoring of the disease progression and the treatment response that in our case lines parallel with the clinical condition. The extension of myocardial fibrosis also has a potential role in prognostication of myocardial functional recovery.
