“Silent” mitral stenosis in sinus rhythm with left atrial thrombus presenting as embolic stroke in an elderly male

Silent mitral stenosis (MS) is an occult clinical entity. It remains hidden because of absence of clinical signs. Left atrial thrombus in mitral stenosis is usually common with atrial fibrillation (AF). We present a case of a 63 year old man who presented with acute stroke and found to have silent mitral stenosis in sinus rhythm with LA thrombus.
