Loeffler endocarditis

Loeffler endocarditis, a form of endocarditis, is one of the two forms of hypereosinophilic syndrome. It is a restricive cardiomyopathy characterized eosinophilia and eosinophilic penetration leading to the fibrotic thickening of portions of the heart (similar to that of endomyocardial fibrosis) and commonly has large mural thrombi. Commonly found in temperate climates.

Common symptoms include edema and breathlessness.

It is named for Wilhelm Löffler.
