Primary endocardial fibroelastosis with dilated cardiomyopathy: report of one case.

We report a case of dilated cardiomyopathy presented in a premature infant of 27 weeks' gestational age. A prenatal sonography revealed left ventricular enlargement. The infant presented with respiratory distress and heart failure soon after birth. Echocardiograms performed after birth showed dilated cardiomyopathy, and endocardial fibroelastosis was suspected. Heart failure progressed despite administration of inotropic agents. The infant died after fifteen days from circulatory failure. Postmortem examination confirmed the diagnosis of endocardial fibroelastosis.
