Impressive Echocardiographic Images of a Mitral Valve Aneurysm

Abstract

A 77-year-old woman with a fractured femur was referred to our hospital because preoperative echocardiography raised suspicion of a mitral valve tumor. She had no history of unknown fever or heart murmur. Transthoracic and transesophageal echocardiography showed severe mitral regurgitation and aortic regurgitation.
