Unusual case of restrictive cardiomyopathy in young

Restrictive cardiomyopathy (RCM) is an uncommon form of cardiomyopathy and is characterized by impaired ventricular filling due to increased myocardial stiffness. In India, RCM is frequently observed in the young and endemic endomyocardial fibrosis is seen in a significant number of cases. We report a case of 15-year-old boy who presented with such a treatable cause of heart failure. On 2D Echocardiography we observed signs of restrictive cardiomyopathy (RCM) and severe mitral and tricuspid regurgitation. RCM is an uncommon form of cardiomyopathy and is usually associated with a poor prognosis. Genetic workup revealed myeloid neoplasm with eosinophilia. Eosinophilic cardiomyopathy is an infrequently reported entity.
