Tricuspid valve surgery in patients with idiopathic hypereosinophilic syndrome

A 53-year-old female with idiopathic hypereosinophilic syndrome underwent recurrent tricuspid valve replacement for Löffler's endocarditis. We review the literature on tricuspid valve surgery in patients with this uncommon disorder.

Acute eosinophilic myocarditis: diagnosis and treatment

Hypereosinophilic syndrome (HES) is a rare disorder of unregulated eosinophilia, which if untreated, may lead to systemic tissue infiltration and inflammation. Cardiac involvement is a common and serious associated complication. We describe a case of HES associated myocarditis mimicking a non-ST elevation MI (NSTEMI). Unlike myocarditis in general, our patient responded well to high dose methylprednisone, the standard of care in HES. We review the clinical presentation, pathophysiology, pathology and treatment of eosinophilic myocarditis related to HES.
