Doughnut appearance of left ventricle in isolated left ventricular endomyocardial fibrosis

摘要

A 55-year-old female presented with worsening dyspnea secondary to left ventricular endomyocardial fibrosis (EMF). Obliteration of left ventricular apex and hypertrophied papillary muscle gave the classical appearance of a “doughnut” on left ventricular angiography.We present here a novel doughnut appearance of left ventricle on angiogram.
