Mitral Valve Destruction by Hodgkin’s Lymphoma-Associated Loefler Endocarditis

We present a case of nearly total posterior mitral leaflet destruction due to Loeffler endocarditis associated with Hodgkin's lymphoma in a 15-year-old adolescent. The patient was treated medically with subsequent surgical mitral valve replacement. Cardiac aspects of hypereosinophilic syndrome are also discussed.
