Abstract: Most cases of restrictive cardiomyopathy (RCM) are caused by cardiac amyloidosis, cardiac hemochromatosis and endocardial fibrosis as the sequela of tropical or nontropical hypereosinophilia or endocardial fibroelastosis. We present herein a case of idiopathic RCM diagnosed by echocardiogram, cardiac catheterization and myocardial biopsy. This patient was a 33-year-old woman. She had been suffering from dyspnea on effort, abdominal fullness and pretibial edema. Persistent atrial fibrillation was seen on electrocardiogram and increase of cardiotrachic ratio (58.6%) on chest X-ray was seen on admission. Echocardiogram revealed a decrease of left ventricular diastolic properties with no decrease of left ventricular ejction fraction. Cardiac catheterization revealed an early diastolic dip and plateau pattern and increased end-diastolic pressure of both ventricles. A myocardial biopsy from the right ventricular wall disclosed mild hypertrophy of myocytes, interstitial fibrosis and endocardial thickening without the deposition of amyloid and hemosiderin.
